A 3-year-old non-lactating pet goat was referred to our clinic due to advanced ocular lesions and blindness of the left eye (Figure 1). According to the case history, two weeks ago, a grass awn penetrated and injured the eye. The awn was removed by the owner immediately. The following day, the goat had serous ocular discharge and photophobia and was referred to a private veterinarian. The veterinarian did not find any remaining piece of the awn and prescribed tetracaine eye drops to be administered twice a day for the next 4 days. The treatment was not successful and the eye’s condition deteriorated the following days.

A case of a two-year-old male Pinscher with a history of discomfort in the right eye was reported. The left eye had been enucleated by the referring veterinarian due to the same symptom with unsuccessful clinical treatment. The Schirmer tear test value was elevated and a decreased intraocular pressure was observed by applanation tonometry. Biomicroscopy revealed profuse corneal edema and keratoconus and fluorescein staining was negative. Gonioscopy and ophthalmoscopy did not provide any relevant data due to the corneal alterations. Bullous keratopathy was diagnosed. Surgery was performed in two steps: 1) superficial keratectomy and 360º conjunctival flap, and 2) superficial keratectomy to restore corneal transparency. Thirty days after the second superficial keratectomy, the third eyelid flap was removed. Conjunctivalization of the upper nasal quadrant of the cornea was observed. The axial portion of the cornea was transparent and vision was restored.

Se reporta un caso de un caballo de silla argentino, macho castrado, de 8 años de edad aproximadamente, el cual fue atendido por el servicio clínico ambulatorio del área de Clínica Médico-Quirúrgica de Grandes Animales de la Facultad de Medicina Veterinaria y Zootecnia de la Universidad de Córdoba. La anamnesis indica que el caballo se encontraba en labores de trabajo de campo en un terreno boscoso, que presento al siguiente día de trabajo aumento en la producción de lágrimas y edema en los párpados del ojo derecho, por lo que le fue aplicado tratamiento con colirio antibiótico por 3 días. Quince días después de aplicado el tratamiento, los encargados del caballo no notaron mejoría, por lo que solicitaron ayuda Médico Veterinaria. En la evaluación Clínica del animal, se encontró en el ojo derecho epifora con secreción purulenta, quemosis, conjuntivitis y edema con marcada lesión del epitelio corneal. Se realizaron pruebas especiales como el test de Schrimer, encontrándose aumento marcado en la secreción lagrimal; posteriormente se realizó la prueba de la Fluoresceína Sódica, evidenciando la marcada ulceración de la córnea. En diagnóstico definitivo, basado en el examen oftalmológico especial y las pruebas realizadas fue de úlcera corneal.

Case series summary A retrospective study was undertaken to review outcomes of keratectomy and corneoconjunctival transposition in cats with superficial and deep corneal sequestra. Information including pertinent history, signalment, ophthalmological findings and postoperative outcome was collected from medical records. Follow-up was obtained by clinical examination, contact with the referring veterinarians and review of medical records or telephone contact with owners. Ninety-seven cats (109 eyes) were included from 2005–2015. The most commonly affected breeds included Persian, Burmese and Himalayan. The mean age at the time of surgery was 6.8 years (median 6.5 years; range 8.0 months–18.0 years). A corneal sequestrum in the contralateral eye was diagnosed in 28 cats (28.9%). Recurrent corneal sequestration was diagnosed in eight cats (nine eyes), with recurrence occurring a mean of 703 days after surgery (range 29–1750 days). Age, sex, breed, depth of sequestration and concurrent ocular disease in the contralateral eye were compared between cats with and without recurrence, with no risk factors for recurrence identified. Relevance and novel information Excellent surgical outcomes have previously been described in a series of 17 cats with superficial and mid-stromal corneal sequestra. This paper adds further information to the literature by describing a larger series of cats, with corneal sequestra affecting the full range of corneal thickness, and good long-term postoperative outcomes.

Evaluation of the role of corneal neovascularization is very important due to a large number of diseases and various effects of exogenous and endogenous factors inducing angiogenesis. Despite the large number of keratopathies accompanied by angiogenesis, ulcerative processes remain the most common cause of vascular growth in stroma. The variety of symptoms accompanying corneal ulcer, as well as the difference in both volume and depth of the corneal lesion dictates the need to assess the value of vascularization in ulcerative lesions of the cornea in small domestic animals. The objects of the study were 317 animals, including 157 cats and 160 dogs. The animals were admitted to the Department of Diseases of small pets of the Department of Veterinary Surgery of Moscow State Academy of Veterinarian medicine and Biotechnology – MVA named after K.I. Skryabin. All animals underwent ophthalmological examination with magnifying glass, a slit lamp, and corneal staining with sodium fluorescein to detect the diameter and depth of the defect. Ulcerative keratitis or corneal ulcer was diagnosed. The severity of the disease and its courses were established to realize the purpose of the study. The symptoms of corneal ulcers were different, including: blepharospasm, mucous, mucopurulent or purulent discharge from the conjunctival cavity, edema and hyperemia of the conjunctiva, infiltration by leukocytes at the site of the ulcer, the diameter of the lesion was from ¼ of the area of the cornea to total, the depth from damage to the multilayer squamous epithelium to a perforated ulcer, myosis, hypopion were observed from the uveal tract or a hyphae. In most cases, vascularization accompanied ulcerative processes in the cornea. It was superficial or mixed. Assessing the role of vascularization in the development of ulcerative processes in the cornea, we attach the great importance to barrier the pathological focus, preserve the integrity of the eye, as well as predict the outcome of the ulcerative process.

Background: Indolent corneal ulcers have been described as superficial ulcers with an associated rim of loose peripheral epithelium Treatment for indolent ulcers include debridement, grid keratotomy, multiple punctate keratotomy, third eyelid flaps, application of cyanoacrylate tissue adhesives, superficial keratectomy, and a debridement with a diamond burr.Case: A 2-month-old female American Quarter Horse was referred to the Ophthalmology Veterinary Section of the Federal University of Rio Grande do Sul (UFRGS), Porto Alegre, Brazil, presenting epiphora and blepharospasm. A local veterinarian doctor had prescribed broad spectrum topical antibiotic and anti-inflammatory drops, although there was no positive response to the treatment for the past two weeks. Ophthalmic examination reveals and moderate discomfort in the left eye, epiphora, and mild corneal edema in the area of the defect. Slit lamp biomicroscopy revealed a superficial corneal ulcer with about 6 mm. Corneal epithelium did not adhere to underlying corneal stroma. The remainder of the ophthalmic examination of the left eye was unremarkable. The diagnosis of a corneal ulcer was made based on these clinical signs and fluorescein staining of the cornea where the stain dissects under the unattached epithelial lip. A handheld battery-operated motorized diamond burr, with a 3.5 mm medium grit tip, was utilized to remove the epithelium. The medical treatment included tobramycin eye drops, and flurbiprofen sodium ophthalmic solution, being applied six times daily, after the procedure, during two weeks, and atropine sulphate 1% was applied once a day, during three days. The foal was hospitalized until healing the corneal ulcer. For two weeks, the foal was assessed daily, and, after that, follow-up visits were scheduled weekly for four months. Healing was defined as the point at which the cornea no longer retained fluorescein.Discussion: Ulcers localized to the corneal epithelium, do not heal within the expected time frame, and have been characterized by epithelial border poorly adherent corneal and being commonly referred as indolent corneal ulcers. In this case, corneal ulcers are chronic and have not responded to an appropriate therapy for 14 days. The corneal ulcer was diagnosed based on history, clinical signs and fluorescein staining of the cornea. Usually, medical treatments provide disappointing results. Surgical treatment aims to remove the loosened epithelium in order to facilitate the growth of new epithelial cells, with stronger adhesion complexes. The utilization of a diamond burr, for the treatment of an indolent corneal ulcer, has been previously reported in humans, and dogs. In the present case, the debridement with a diamond burr was chosen on account of excellent results obtained in previous studies in humans and dogs, when treating indolent corneal ulcers. In the current case, the corneal ulcer healed in ten days, while in a study comparing the outcome in 23 horses treated by debridement, grid keratotomy, or superficial keratectomy, the mean times until complete healing were 15, 16 and 23 days, respectively. In the present case, debridement with diamond burr was effective in the treatment of a recurrent corneal ulcer in a foal.

When presented with an animal exhibiting signs of keratitis (inflammation of the cornea), such as impaired vision, mucoid discharges, redness, swelling, and corneal oedema, most veterinarians would think of bacteria, viruses, or fungi as the potential causative agent(s). However, evidence has arisen in recent years of a possible connection between the protozoan Acanthamoeba and keratitis in animals. Acanthamoeba infection is underdiagnosed, but potentially common, in animals. In view of the paucity of evidence regarding Acanthamoeba keratitis (AK) in animals, this review has been written to increase awareness of veterinary professionals of the potential threat associated with AK and to stimulate more studies into the extent of occurrence and clinical impact of AK in animals.

Sulfur mustard gas (HD), a synthetic vesicating agent used effectively as a major chemical warfare agent during World War 1, continues to be a modern day threat agent. Unfortunately there is no specific pretreatment or antidotal therapy for those who may become exposed. Whole body exposure results in cutaneous, respiratory and ocular effects. of these, eye impairment leads to the most immediate incapacitation. However HD-induced eye lesions remain to be fully characterized. In the present study we explore histological, ultrastructural and immunopathological effects of a vesicating dose of HD in rabbit cornea occurring during the first 24 hours following exposure.A 0.4μl drop of liquid HD was placed on the left cornea of anesthetized rabbits. The right cornea served as an unexposed control. Following exposure animals were returned to their cages and given appropriate care by an attending veterinarian. Eye injury was evaluated by clinical observations and given scores of severity from simple conjunctival redness to apparent corneal damage.

This report describes the clinical presentation, diagnosis, and histopathologic features of oculodermal melanocytosis in a young dog. A 3-year-old male neutered Labrador Retriever presented with conjunctival and scleral hyperpigmentation of the right eye, with concurrent ipsilateral cutaneous hyperpigmentation involving the right side of the face. Initial skin and conjunctival biopsies revealed an accumulation of histologically benign melanocytes within the dermis and conjunctival stroma, respectively. Enucleation was elected 19 months later by the referring veterinarian due to the progression of ocular pigmentation with concurrent marked corneal lipidosis and the suspicion of a scleral mass. On gross and histopathologic examination of the globe, there was marked panuveal melanocytosis with extension into the sclera, bulbar conjunctiva, and connective tissue surrounding the optic nerve, as well as sharply demarcated ipsilateral hyperpigmentation of the facial skin. The findings are characteristic of oculodermal melanocytosis (nevus of Ota), a dermal melanocytic hamartoma presenting as cutaneous facial hyperpigmentation that corresponds to the distribution of the ophthalmic and maxillary branches of the trigeminal nerve, often with ipsilateral ocular involvement.

The short bibliography referring to the anatomy and pathology of the eyeball of turtles poses a challenge for veterinarians and conservationists given the increasing presence of this type of turtle in veterinary and wildlife centres. Although they nest on land, these animals spend a large part of their lives in the ocean, which entails a series of eye adaptations such as well-developed nictitating membranes, palpebral scales, highly sensitive corneas, or sclerotic rings to protect the eye. In our study, we performed a morphometric analysis of the loggerhead turtle (Caretta caretta) eyeball and its internal structures using advanced imaging techniques such as computed tomography (CT). To the best of the authors’ knowledge, there have been no studies published that describe the CT intraocular measurements of presumed normal loggerhead turtle eyes.

Las úlceras corneales son patologías que afectan la integridad de la córnea. Dependiendo del tipo de lesión, puede necesitar un tratamiento quirúrgico, como en el caso de las úlceras corneales profundas ya que estas atraviesan el epitelio corneal. Generalmente es una patología que se presenta con frecuencia en las clínicas veterinarias de pequeños animales, por esta razón en este trabajo se analiza los diferentes injertos biológicos utilizados en la corrección de úlceras corneales en caninos, sus componentes, sus beneficios, así como los diferentes métodos de conservación utilizados para estos. Se hace énfasis en la membrana amniótica puesto que este biomaterial presenta diferentes componentes que lo resaltan de los demás, viéndose reflejado en los resultados del tratamiento. Además, tiene más aportes investigativos hablando sobre estos beneficios, lo que justifica la recomendación de su uso frente a otras membranas utilizadas. En cuanto a los hemoderivados se mencionan los beneficios que cada uno de estos contienen además de su acción como adyuvante en el tratamiento de las úlceras corneales profundas. Finalmente se evaluó la teoría en el reporte de un caso clínico de descemetocele por úlcera profunda en córnea izquierda, no perforado.

Las ulceras corneales son alteraciones frecuentes en oftalmología veterinaria, como resultado de diferentes etiologías que desencadenan graves secuelas derivadas al epitelio corneal pudiendo producir una pérdida importante de la visión debido a la opacificación cicatricial y astigmatismo sequerales. El objetivo de la presente investigación evaluar el efecto terapéutico del suero autólogo mediante la preparación y manejo de la terapia en la práctica oftalmológica en conejos. La metodología consistió en utilizar 10 conejos los cuales fueron valorados el grado de ulceración bilateral (superficiales o profundos), posterior se realizó la extracción de sangre y la preparación del suero aplicando dos gotas de suero en el ojo derecho con intervalos de 8 horas por 7 días consecutivos, en el ojo izquierdo se aplicó el grupo control con aplicación de suero fisiológico, posterior los animales fueron sacrificados y los ojos fueron evaluados por los efectos observados clínicamente en la superficie ocular y córnea y por análisis histopatológico. Los resultados indicaron que fue menor el porcentaje de ojos tratados con suero autólogo con signos de inflamación, fibrosis, fibroblastos, neovascularización y epitelización, fueron menores que los ojos que no recibieron ese tratamiento. Sugiriendo que podría ser efectivo emplear el suero autólogo en para tratar las ulceras corneales, sin embargo, las diferencias no fueron significativas estadísticamente. Se concluye que es necesario evaluar la efectividad del suero autólogo bajo otros protocolos de aplicación con menor tiempo entre aplicaciones o tratamientos con más días, dado que la investigación sugiere que podría ser útil para tratar esta patología.

ABSTRACT Owners of dogs with ocular issues often suspect their pet’s eye problems are linked to recent grooming visits. A medical records search was performed to identify dogs presenting with ocular complaints initially noted within 24 hr of a commercial grooming appointment. Data collected included signalment, type of injury, treatment, and notations regarding behavioral issues potentially contributing to injury. One hundred sixty-one episodes involving 159 dogs were identified. Male dogs accounted for 57% of episodes. Median age at presentation was 59 mo. Shih tzu were involved in 34% of incidents, and 71% involved small-breed dogs. Aggressive or reactive behaviors were reported in 33% of dogs. Corneal ulceration was the most common injury (71% of incidents), followed by conjunctivitis (11%), eyelid lacerations (7%), and subconjunctival hemorrhage (6%). Surgical management was required in 14% of cases, including four dogs that underwent enucleation. Ocular injury during grooming appointments can occur via several mechanisms including trauma, exposure to grooming products, or inadvertent strangulation. Small-breed dogs, particularly shih tzu, appear to be at increased risk. Reactive or aggressive behavior likely increases risk of ocular injury. Veterinarians can help limit grooming-associated ocular injuries by recommending behavioral or pharmacological interventions before grooming visits.

Este estudio aborda la eficacia del suero autólogo como ayuda en la cicatrización de las úlceras corneales, indistintamente del origen de dicha patología. Se estableció una muestra de 10 pacientes, en una investigación cuantitativa de tipo experimental, que se llevó a cabo en la Clínica Veterinaria Garras y Patas. Los criterios de inclusión se centraron en pacientes positivos a la prueba de fluoresceína, para diagnosticar y clasificar el tipo de úlcera, mientras que los de exclusión incluyeron pacientes con hematocritos menores a 37% y razas miniaturas. Los materiales que se utilizaron fueron un hemoglobinómetro, centrifuga, tirillas reactivas de fluoresceína, historias clínicas e instrumentos de medición como jeringuillas y goteros. Se extrajo 10 ml de sangre tomada de la vena yugular del paciente, que luego se colocó en tubos estériles vacutainer sin anticoagulante, para someterse al proceso de centrifugación a 3000 rpm durante 15 minutos, para obtener el suero autólogo, se instauro el respectivo tratamiento y frecuencia del suero autólogo que serán anotadas en las fichas de control. Los resultados mostraron que el 60% de las úlceras fueron superficiales, con remisión del 100% de los casos; el 20% fueron profundas, con cicatrización completa en el 100% de los pacientes; y el 20% eran estromales, con cicatrización corneal con el 50% de los casos, mejorando notablemente el tiempo de cicatrización en ulceras de tipo superficiales y profundas con el uso del suero autólogo como coadyuvante en el tratamiento.

Lyme Disease continues to be a complex phenomenon, medically, culturally, epistemologically. Based on a theoretical framework steeped in feminist science studies and post-human onto-epistemologies, I suggest that conventional biomedicine has failed not only practically as far as helping patients suffering from Lyme and other "emergent diseases," but also conceptually as it applies the determinist monocausal infectious disease model to Lyme. Several recent essays on autoimmunity have developed tools based on both science studies and deconstruction that pinpoint the conceptual shortcoming of dominant immunology, which presumes a stable and antagonistic ontology of immune self and pathogenic other. The authors suggest to replace this ontology with an ecology of entangled becomings. My argument is developed by weaving together the human-centered Lyme conundrum with that of horses because Lyme seems better understood by veterinarians than human physicians. While I critically examine an important official study on equine borreliosis, conducted by Cornell University's Veterinary College, which is characterized by the typical reductionist and mechanistic approach, I nevertheless concede that it has yielded a better testing system than what is available in the human context. But ultimately, I end up making the case for an energy-medicine approach to healing rather than a biomedical "cure" through the case study of my horse Caspio, who suffers from the chronic stage of the illness, and whom I have rehabilitated over the course of nearly a decade. His etiology simultaneously blends into my own, as I move from self- to cross-species case history in this hybrid piece. Leaning on the notion of entangled ecologies developed in recent literature, which proposes to think of immune-system related illnesses as dynamic relations of becoming together, I conclude with the notion of balance —mental, immunological, and biomechanical— which I have striven to achieve with Caspio through acupuncture and the art of classical training: learning to live well with the embodiment of (at times debilitating) symptoms, rather than engaging in pharmacological warfare.

Introduction Guinea pigs are popular as domestic pets but there is limited information on the health of the wider pet population. This study aimed to report demography, commonly diagnosed disorders and mortality of guinea pigs under UK primary veterinary care. Methods Diagnosis and mortality information on guinea pigs was extracted from anonymised UK primary-care clinical records in VetCompass. Results From 51,622 guinea pigs under primary veterinary care during 2019, a specific breed was not recorded in 50,098 (97.05%). Of guinea pigs with information recorded, 23,206 (47.33%) were female and 25,828 (52.67%) were male. There were 1,020 (2.08%) neutered and 48,014 (97.92%) entire. Median adult bodyweight overall was 1.05kg (interquartile range [IQR] 0.90–1.19, range 0.40–2.66). From a random sample of 3,785/51,622 (7.33%) guinea pigs, the most prevalent disorders were overgrown nail(s) (n = 1,005, 26.55%, 95% confidence interval [CI] 25.15–27.99), dermatophytosis (228, 6.02%, 95% CI 5.29–6.83) and corneal ulceration (189, 4.99%, 95% CI 4.32–5.74). Among the 30 most common disorders, females showed predisposition for 3 disorders and males showed predisposition for 5 disorders. The disorder with the youngest age of affected animals was dermatophytosis (1.11 years) while weight loss had the oldest age of affected animals (4.64 years). From 757 recorded deaths, the median age at death overall was 4.03 years (IQR 2.56–5.44, range 0.17–10.00). Among deaths with a recorded cause, the most common causes of death were anorexia (n = 82, 13.87%, 95% CI 11.19–16.93), collapsed (58, 9.81%, 95% CI 7.54–12.50) and peri-anaesthetic death (20, 3.38%, 95% CI 2.08–5.18). Conclusions These results can assist veterinarians and owners by providing demographic, disorder and mortality benchmarks that support improved clinical care and welfare outcomes in guinea pigs. Many common disorders in guinea pigs were husbandry related.

La thelaziosis bovina está causada por Thelazia rhodesi, T. skrjabini y T. gulosa, aunque la especie más prevalente en Europa es la primera de ellas. Thelazia rhodesi es un nematodo (orden Spirurida, familia The- laziidae) que parasita el globo ocular del ganado vacuno, búfalos, cebúes, bisontes y, con menor frecuencia, caballos y pequeños rumiantes. Se localiza en la superficie corneal, sobre la membrana nictitante y en el saco conjuntival. Tiene un ciclo biológico indirecto, actuando como hospedadores intermediarios dípteros de la familia Muscidae. En este estudio se describe un caso de thelaziosis ocular en un toro de lidia (Bos taurus), muerto en la plaza de toros de Murcia en septiembre de 2014, procedente de una ganadería localizada en el su- roeste de la Península Ibérica. Durante el primer y segundo reconocimiento veterinario del animal en la plaza de toros, se observó la existencia de lagrimeo abundante, pero a pesar de ello el animal reaccionaba positivamente a estímulos visuales realizados en el campo visual de ambos ojos, conjunta e independientemente. A pesar del lagrimeo constante, el animal fue considerado apto para la lidia. Durante esta no se observó anormalidad alguna en el comportamiento del toro en relación con el sentido de la vista. La inspección ocular post mortem realizada en el desolladero de la plaza permitió detectar la presencia de nematodos de 8-20 mm de longitud tanto en el saco conjuntival como en la superficie de la córnea, que fueron extraídos con ayuda de pinzas y conservados en etanol al 70%. La identificación microscópica específica de los ejemplares encontrados se realizó en base a los criterios morfométricos descritos por Gupta y Kalia (1978) y Naem (2007a,b), siendo identificados como Thelazia rhodesi. Se trata de un nematodo con tropismo ocular que puede aparecer en el toro de lidia, gana- derías explotadas en régimen extensivo en zonas templadas o cálidas, cuyos condicionantes ambientales van a favorecer la proliferación de los hospedadores intermediarios y el desarrollo de la parasitosis. Por ello, la thelaziosis ha de considerarse en el diagnóstico diferencial de patologías oculares del toro de lidia cuyo cuadro sintomático incluya intranquilidad, agudeza visual disminuida, epífora y prurito en la zona periocular. En el conocimiento de los autores, esta es la primera vez que se publica un caso de parasitación por Thelazia rhodesi en el bovino de lidia. Bovine thelaziosis is caused by Thelazia rhodesi, T. skrjabini and T. gulosa, although the most prevalent species in Europe is the first of them. Thelazia rhodesi is a nematode (order Spirurida, family Thelaziidae) para- sitizing the eye of cattle, buffalo, zebu, and bison and, less frequently, horses and small ruminants. It is located on the corneal surface, under the lids and nictitating membrane and in the conjunctival sac. Thelazia spp. has an indirect life cycle, acting diptera of the family Muscidae as intermediate hosts. This study presents a case of thelaziosis in a fighting bull (Bos taurus), dealt in the bullring of Murcia in September 2014, coming from a farmer located in the Southwest of the Iberian Peninsula. During the first and second veterinary examinations of the animal, abundant tearing was observed, but despite this, the animal reacted positively to visual stimuli made in the visual field of both eyes, jointly and independently. The fighting bull was considered useful during the mentioned veterinary examinations, although it presented constant epiphora. During the fight, no abnormality was observed in the behavior of the bull in relation to the sense of sight. The post mortem ocular inspection in the pit of the square revealed the presence of nematodes 8-20 mm length in both the conjunctival sac and the surface of the cornea, which were extracted using tweezers and preserved in 70% ethanol. The specimens were identified as T. rhodesi according to the morphometric criteria described by Gupta and Kalia (1978) and Naem (2007a, b). This is a nematode species with ocular tropism that can appear in the fighting bull, farms exploited in extensive regime in temperate or warm areas, whose environmental conditions will favor the proliferation of intermediate hosts and the development of parasitosis. Therefore, thelaziosis must be considered in the differential diagnosis of ocular pathologies of fighting bull whose signs include restlessness, decreased visual acuity, epiphora and pruritus in the periocular area. To the knowledge of the authors, no case of Thelazia rho- desi infection has been reported in fighting bull.

Food supply veterinarians who intend to enter dairy cattle practice or other related career activities are in need of upgraded skills to better serve the dairy industry as it continues to evolve. As knowledge in all phases of veterinary medicine increases, the time available for students to increase their specific abilities within the conventional professional curriculum becomes more difficult, especially for those with food supply interests, as they are a minority of students competing for time and resources. The dairy industry has need of skilled veterinarians well-versed not only in their traditional capabilities, but also with an understanding of the complete picture of that industry as a "farm-to-fork" experience. Society at large also stands to benefit from a presence of skilled dairy veterinarians contributing to the production of safe, affordable dairy foodstuffs in a manner deemed sustainable and humane. Veterinarians in practice can and do acquire the necessary skills to make themselves relevant to their clients and consumers; however, better preparation of entry-level veterinarians can increase their value to their employers, their clients, themselves, and society in a more timely manner. Cornell University's College of Veterinary Medicine developed the Summer Dairy Institute (SDI) to provide an avenue for advancing skills of new veterinarians as a means to address the current and future needs of the dairy industry. The SDI has accumulated, from its nine years of existence with 183 participants from 38 veterinary colleges, valuable insights to aid in constant improvement of its offerings. This article describes the need, concept, and experience with the program.

Corneal injuries in pets cause severe suffering and vision impairment, creating significant challenges in the field of veterinary medicine. It is important to understand that the cornea lacks the inherent capability to regenerate itself through the administration of substances such as hyaluronic acid or antibiotics, which are commonly utilized by veterinarians for managing edema and infections in animals. It has been shown that platelet rich fibrin extract (PRFE) is effective in healing both deep corneal ulcers and superficial keratitis. In this case report, the use of PRFE in dogs and cats which showed promising results.

Background: Bullous Keratopathy (BK) is characterized by decompensation of the corneal stroma resulting in visual impairment by corneal opacity, discomfort, excessive tearing, blepharospasm and pain. The aim of this study was to report a case of BK in a dog and the complete recovery of the ocular structure and visual function, with a third eyelid flap associated with the use of autologous blood serum topically.Case: A 2-year-old Shih Tzu male dog, weighing 4.3 kg, with recurrent bilateral eye discomfort was brought to Ophthalmologist Veterinarian Assistance. The patient had already been seen by other veterinarians, but the signs returned in a short period of time after the prescription was suspended. During physical examination it was observed moderate blepharospasm in the right eye, epiphora in the left eye, and in both eyes was noted exophthalmos, medial corneal entropion, caruncle trichiasis and ectopic cilia in the upper and lower eyelids. Fluorescein test was positive in both eyes, and a large bullous, opaque and gelatinous lesion with irregular appearance was observed occupying a large part of the cornea of the right eye. Superficial corneal ulcer was diagnosed in left eye and BK in right eye, both probably in consequence of ectopic cilia presence. Surgical intervention was made, with the cauterization and excision of the ectopic cilia and third eyelid flap in the right eye. The cauterization of caruncle trichiasis was not authorized by the owner. Moxifloxacin eye drops in the dose of one drop four times a day in both eyes, lubricant based on hyaluronic acid in the dose of one drop four times a day in both eyes, and autogenous blood serum, obtained from the centrifugation of a blood sample of the dog itself, in the dose of one drop every hour in the right eye for 24 hours, and meloxicam in the dose of 0.1 mg/kg every 24 h for 3 days were prescribed. Elizabethan collar was recommended until removal of the third eye flap. During the surgery, a sample of eye secretion was collected and sent for culture and antibiogram and did not show growth of microorganisms. After seven days of the procedure, the animal did not show eye discomfort and corneal ulcer in the left eye was healed. The third eye flap remained stable until the return of 28 days and after removal of the capton, adhesions were identified, which were removed with Castroviejo scissors after application of topical anesthetic proxymetacaine hydrochloride eye drops. A fluorescein test was performed and the absence of corneal keratitis was confirmed. Discrete corneal scars (macula) were identified.Discussion: The patient in this report had several changes in ocular morphology that favored the formation of recurrent injuries which contributed to the formation of BK. The use of topical medications as unique treatment was not performed due to the severity of the lesion and the presence of alterations such as medial entropion, caruncle trichiasis and ectopic cilia that needed surgical corrections to resolve the causes of the lesions. In order to protect the cornea and provide compression of its epithelium, a third eyelid flap was performed, a low-invasive procedure that is quick and easy to perform. Ectopic cilia were cauterized to eliminate one of the causes of the corneal injuries, however, the other changes could not be corrected because they were not authorized by the owner. The adjuvant uses of ocular lubricant based on hyaluronic acid, a broad-spectrum topical antibiotic and mainly autogenous blood serum favored the epithelial reconstruction of the cornea by providing protection, vitamins, growth factors, immunoglobulins, anti-collagenolytic and bacteriostatic substances. The protocol used it enabled a rapid reduction in patient discomfort, reversal of injuries and recovery of visual function.

Marijuana toxicosis is typically seen by companion animal veterinarians. However, with increased marijuana availability, there is a greater potential for toxicosis in other species. Herein we describe a case of suspected marijuana toxicosis in a female and a male American Mammoth donkey, aged 8 y and 20 y, respectively, fed cannabis buds. Both cases were presented because of depression and lethargy. However, the jenny had ataxia, mild colic, tachycardia, tachypnea, and decreased tongue tone. Plasma samples from the jenny on presentation and 3 d following hospitalization were submitted to the Kansas State Veterinary Diagnostic Laboratory to be screened for cannabinoids using high-pressure liquid chromatography coupled with tandem mass spectroscopy (HPLC-MS/MS). A single serum sample from the jack was taken on presentation and submitted to the Animal Health Diagnostic Center at Cornell University for Δ9-tetrahydrocannabinol (THC) and cannabidiol analysis using HPLC-MS/MS. THC was detected in all samples. Clinical signs were noted 24–36 h after ingestion, which included mild-to-moderate neurologic deficits, mild colic, tachycardia, tachypnea, and decreased tongue tone. Both donkeys recovered uneventfully within 24 h of peak effects. Utilizing a cannabinoid screening assay in collaboration with a veterinary diagnostic laboratory may be useful when an equine practitioner suspects marijuana toxicosis in a patient.

ABSTRACT A 1 yr old castrated male shih tzu was evaluated for an acute right rear limb lameness and hyphema in the anterior chamber of the right eye. On initial examination, the dog was non-weight bearing on his right rear limb. Ophthalmic examination revealed a centrally located, superficial corneal ulcer in the right eye and blood in the anterior chamber. Radiographic findings of the pelvis and right rear were suggestive of avascular necrosis of the right femoral neck with resultant fracture and possible avascular necrosis of the left femoral neck. The dog presented 20 days later for evaluation of an acute left rear limb lameness. A left distal femur Salter-Harris type II fracture; a nondisplaced, healing right pubic fracture; and a healing right zygomatic arch transverse fracture were seen on radiographs. The dog’s initial injuries were attributed to a routine fall at home, and radiographic interpretation suggested that this was plausible. Subsequent patient visits, evaluation of additional injuries, and interviews with the owner indicated that both animal and domestic abuse had occurred. Veterinarians must be alert to recognize signs of animal abuse and must be aware of the connection between animal and domestic abuse.

In this study, the incidence of eye diseases in cats and dogs brought to Burdur Mehmet Akif Ersoy University Animal Hospital Surgery Clinic between 2021-2022 was investigated. The material of the study consisted of 200 patients (103 dogs and 97 cats). Eye pathology was diagnosed in 35.05% of the examined cats and 35.92% of the examined dogs. The most common cat breed with eye pathologies was mixed breeds with a rate of 29.8%, and the most common dog breed was Golden Retrievers with a rate of 82.3%. When the anatomical localization of the pathologies encountered in the cats and dogs included in the study was evaluated, it was seen that the most common anatomical region with pathologies in cats was the cornea, and the most common anatomical region with pathologies in dogs was the lens. According to the data recorded during the study, the most common eye pathologies were corneal damage 14.7% for cats and senile nuclear sclerosis 36.75% for dogs. In conclusion, with this study, it was aimed to help veterinarians to approach eye diseases by identifying the most common eye diseases in cats and dogs brought to Burdur Mehmet Akif Ersoy University Animal Hospital Surgery Clinic.

Given the global threat of antimicrobial resistance, it is imperative that veterinary graduates are effective antimicrobial stewards. Veterinary students learn the principles of antimicrobial stewardship explicitly, through pre-clinical coursework, and implicitly, through the cases they each encounter on clinical rotations. We aimed to understand the influence of pre-clinical versus clinical learning on veterinary students’ knowledge and awareness of antimicrobial concepts to guide efforts to improve instruction in these areas. To assess knowledge acquisition and to explore student perceptions of antimicrobial stewardship, a standardized online survey was administered to Cornell University veterinary students at two timepoints: in August 2020 before clinical rotations ( N = 26 complete responses and N = 24 partial responses) and again in May 2021 after their clinical rotations ( N = 17 complete responses and N = 6 partial responses). Overall and section-specific confidence and knowledge scores were calculated, using pairwise deletion for incomplete responses. Students generally had low confidence in antimicrobial topics and correctly answered only half of knowledge questions correctly; they performed the best on antimicrobial resistance knowledge questions. There were no significant differences in knowledge or confidence after clinical rotations. On average, students had only read one antimicrobial stewardship guideline. Students reported that human health care providers contributed more to antimicrobial resistance than veterinarians. In conclusion, graduating veterinary students at our institution have significant knowledge gaps in critical principles that are essential to become antimicrobial stewards. Explicit instruction in antimicrobial stewardship is necessary in the pre-clinical and clinical coursework, and the practical use of antimicrobial stewardship guidelines should be emphasized.

AbstractObjectiveTo establish normative data for selected ocular diagnostic tests and commensal conjunctival microflora and describe the incidence of ocular pathology in Chilean flamingos.Animals StudiedA total of 41 Chilean flamingos were examined at the Blank Park Zoo in Des Moines, Iowa.ProceduresIn 20 flamingos, blink rate was assessed undisturbed in their exhibit, then gentle manual restraint was used to assess palpebral fissure length (PFL), aqueous tear production (phenol red thread test [PRTT] in one eye, endodontic absorbent paper point tear test [EAPPTT] in the other), intraocular pressure (IOP; rebound tonometry), and fluorescein staining. Twenty‐one other flamingos were brought to a darkened area for neuro‐ophthalmic examination, slit lamp biomicroscopy, and indirect ophthalmoscopy. Swabs from seven flamingos were used for ocular microbiome evaluation.ResultsResults are presented as mean ± standard deviation (range). Flamingos comprised 23 females/18 males, aged 11 ± 9.1 (0.7–40) years. Test results: blink rate, 3.7 ± 2 (1–9) blinks/min; PFL, 11.2 ± 1.2 (9–14) mm; IOP, 14 ± 3.2 (10–22) mmHg; EAPPT, 10.2 ± 2.8 (9–14) mm/min; PRTT, 6.8 ± 2.5 (3–13) mm/15 s. Dazzle reflex was positive in four birds examined. Pathologies included cataracts (n = 7 birds), corneal fibrosis (n = 3), endothelial pigment (n = 2), uveal cysts (n = 1), lens luxation (n = 1), and uveitis (n = 1). Ocular microbiome showed high diversity of taxa.ConclusionsBaseline ocular parameters and incidence of ophthalmic pathology assist veterinarians with disease screening for Chilean flamingos, while the ocular microbiome showed high diversity.

Progressive retinal atrophy (PRA) is a term used in veterinary medicine to describe inherited and progressive retinal diseases characterized by progressive retinal degeneration and loss of vision. In the Golden Retriever (GR) breed, the mutations associated with PRA have an autosomal recessive inheritance pattern. This study aimed to verify the allele frequencies of PRA1, PRA2, and PRA-prcd in the GR breed in Brazil. A total of 121 GR DNA samples (n = 66 females and n = 55 males) were analyzed. All animals assessed in this study were identified as wild-type (121/121 animals; 100%) for PRA1 and PRA2 mutations; therefore, no carrier or homozygous animals were identified in this population. For the PRA-prcd mutation, 118 animals (118/121 animals; 97.52%) were wild-type. Three animals were genotyped as heterozygous for PRA-prcd (3/121 animals; 2.47%), demonstrating that this mutation is still present in some bloodlines and animals in Brazil, even with a rare prevalence. Five animals (5/121 animals, 4.2%) had a previous eye disease, which was diagnosed by a veterinarian as entropion (2 animals), keratoconjunctivitis sicca (1 animal), corneal ulcer (1 animal), and bilateral blindness (1 animal). This dog with bilateral blindness was identified as wild type homozygous for three mutations assessed in this study; therefore, blindness was not associated with the investigated mutations. In addition, the vast majority (98.3%) of Brazilian breeders assessed in this study were unaware of these mutations as a cause of blindness in the Golden Retriever. Therefore, the present study will serve to disseminate knowledge about PRA and its genetic etiologies, as well as to support future studies with other Brazilian GR populations.
