Objectives: To compare the effectiveness of topical and retobulbar anesthesiain term of pain relief in patients subjected to cataract surgery. Material and methods: Thiscomparative study was conducted at Department of Ophthalmology, Bahawal Victoria HospitalBahawalpur from 18th July, 2012 to 18th January, 2013. Total 100 patients with cataract wereincluded in this study. Results: Mean age of the patient was 64.14 ± 8.7 years. No. of patientsin RA group who reported the pain scores (0- 4) during cataract surgery, was 46 (effectivenesswas positive in 92% patients), while it was 33 (effectiveness was positive in 66% patients) in TAgroup. A significant difference between effectiveness of both anesthetic group was observed. (P= 0.001). Conclusion: It is observed that topical anesthesia in cataract surgery is a simple, safeand noninvasive technique but it cannot be proposed as a very good alternative to retrobulbaranesthesia in cataract surgery of all patients regarding its effectiveness interms of pain relief.

Background/aimTo report the outcome of penetrating keratoplasty (PKP) in Irish patients with congenital hereditary endothelial dystrophy (CHED).MethodsA retrospective case series review of patients with CHED who underwent PKP was conducted. The outcomes of PKP in 14 patients with CHED at the Royal Victoria Eye and Ear Hospital in Dublin from 1978 to 2013 were described following case note review. The main outcome measures were best-corrected visual acuity (BCVA) and graft survival.ResultsThirty-three corneal transplants were performed, which included 32 PKPs and one Descemet’s stripping endothelial keratoplasty. Twenty-four eyes underwent primary corneal grafts and nine eyes had regrafts. The graft survival rates at final follow-up were 37.5% and 33% in the primary graft and regraft groups, respectively. Preoperative BCVA was 20/200 or worse in all patients. At the final postoperative visit, the BCVA was 20/80 or better in four eyes following primary PKP, 20/160 in one eye following regrafting and was 20/200 or worse in all other eyes. The mean time to graft failure was 16 months (range 0–37 months). The mean follow-up time was 101 months (range 12–252 months). Fifty per cent of the patients continue to attend for follow-up.ConclusionsThis study has demonstrated a poor outcome from PKP for CHED in this Irish cohort. This arises from a combination of dense amblyopia and a high risk of graft failure in the long term.

Objectives: To find out the frequency of retinopathy in low birth weight infant presenting at tertiary care hospital, Bahawalpur. Study Design: Cross sectional study. Setting: Department of Ophthalmology, Bahawal Victoria Hospital, Bahawalpur. Period: From July 2018 to December 2018. Material & Methods: Neonatal eye examination was performed for ROP. Results: Total 78 neonates were recruited for present study and ROP was assessed. Mean gestational age of neonates was 32.54 ± 3.79 weeks. Mean weight was 1445.51 ± 517.373 grams. Out of 78 neonates, ROP was observed in 28 (36%) neonates. ROP was found in 27 (42.19%) neonates of premature group and in 1 (7.14%) neonates of at term group. ROP was found in 1 (3.23%), 5 (29.41%) and 22 (73.33%) neonates respectively in weight group 1500-2500 g, 1000-1500 g and <1000 g group. Male neonates were 35 (44.87%) and female neonates were 43 (55.13%). Development of ROP was not significantly (P = 0.248) associated with gender of the neonates. Statistically significant association between ROP and oxygen supplementation was observed with p value 0.021. Conclusion: Results showed higher number of patients with ROP. Association of development of ROP with gestation was highly significant. Oxygen supplementation and oxygen concentration was also associated with ROP. Findings also showed no effect of gender and duration of hospital stay on ROP.

Background/aimsTo report refractive outcomes from an National Health Service (NHS) cataract surgery service and assess if results meet suggested benchmark standard.MethodsDetails of all patients undergoing cataract surgery in the Southern General and New Victoria hospitals in Glasgow, UK, between November 2006 and December 2016 were prospectively entered into an electronic database. Patients were reviewed 4 weeks postoperatively in the eye clinic and underwent refraction at their local optometrist prior to this appointment. Surgically uncomplicated cases with in the bag’ non-toric intraocular lens implantation were included. Patients with previous laser refractive procedures or failing to achieve 6/12 acuity or better postoperatively were excluded. Proximity to targeted postoperative refraction was documented.ResultsOver this 10-year period, 11 083 eyes underwent cataract surgery. Of these, 8943 eyes of 6936 patients (80.69%) met the inclusion criteria and had both target and postoperative outcome refraction recorded. The mean difference between the targeted and outcome refraction was −0.07 D (SD 0.67). The mean absolute error was 0.50 D. Postoperative refraction was within 1 D of target refraction for 7938 eyes (88.76%) and within 0.50 D for 5577 eyes (62.36%).ConclusionRefractive outcomes following routine cataract surgery reported here are well within the targets recommended by the Royal College of Ophthalmologists and European guidelines, but suggest that higher cataract refractive outcome benchmark standards may not yet be a realistic expectation for all NHS units with current biometry practice.

Purpose: To report the visual, refractive and tomographic outcomes following the implantation of intrastromal corneal ring segments (ICRS) (Ferrara rings, AJL Ophthalmics, Miñano, Spain) in eyes with a history of keratoconus and corneal cross-linking using the Ferrara ring nomogram. Methods: Retrospective, interventional case series performed at the Corneoplastics Unit, Queen Victoria Hospital, East Grinstead, United Kingdom. Results: 21 eyes of 19 patients with a history of keratoconus and prior corneal collagen cross-linking had Ferrara Intrastromal Corneal Ring Segments implanted between December 2015 and October 2017. The number, thickness and length of ring segments was chosen based on the Ferrara ring company nomogram. Mean uncorrected visual acuity (UDVA) improved from 0.88 to 0.52 logMAR (p < 0.001). Mean corrected visual acuity (CDVA) improved from 0.47 to 0.36 logMAR (p = 0.046). The percentage of eyes achieving 20/40 UDVA and CDVA increased from 5% to 38% and from 38% to 67%, respectively. Of the eyes, 52.3% gained at least two lines of CDVA. The spherical equivalent improved from −7.51D to −3.76D (p < 0.001) and the refractive astigmatism magnitude improved from 5.14D to 2.76D (p = 0.004). There were significant improvements in the corneal tomography with mean keratometry (KM) improving from 50.40D (3.53) to 48.24D (3.00) (p = 0.01) and keratometric astigmatism magnitude improving from 5.14D (2.91) to 2.76D (1.67) (p = 0.004). Conclusion: Insertion of Ferrara rings in keratoconic eyes with a history of prior cross-linking using the company nomogram results in significant improvements in visual, refractive and tomographic outcomes.

AbstractBackgroundDiagnostic error is a major preventable cause of harm to patients. There is currently limited data in the literature on the rates of misdiagnosis of doctors working in an ophthalmic emergency department (ED). Misdiagnosis was defined as a presumed diagnosis being proven incorrect upon further investigation or review.MethodsIn this retrospective audit, data was collected and analysed from 1 week of presentations at the Royal Victorian Eye and Ear Hospital (RVEEH) ED.ResultsThere were 534 ophthalmic presentations during the study period. The misdiagnosis rates of referrers were: general practitioners (30%), optometrists (25.5%), external hospital EDs (18.8%), external hospital ophthalmology departments (25%) and private ophthalmologists (0%). Misdiagnosis rates of RVEEH doctors were: emergency registrars (7.1%), RVEEH residents (16.7%), first-year registrars (5.1%), second-year registrars (7.1%), third-year registrars (7.7%), fourth-year registrars (0%), senior registrars (6.9%), fellows (0%) and consultants (8.3%).ConclusionsThe misdiagnosis rates in our study were comparable to general medical diagnostic error rates of 10–15%. This study acts as a novel pilot; in the future, a larger-scale multi-centre audit of ophthalmic presentations to general emergency departments should be undertaken to further investigate diagnostic error.

PurposeTo assess incidence, risk factors, presentation and final visual outcome of patients with Acanthamoebakeratitis (AK) treated at the Royal Victorian Eye and Ear Hospital (RVEEH), Melbourne, Australia, over an 18-year period.MethodsA retrospective review of all cases of AK managed at RVEEH between January 1998 and May 2016 was performed. Data collected included age, gender, affected eye, signs and symptoms, time between symptoms and diagnosis, risk factors, presenting and final visual acuity (VA), investigations, medical treatment, surgical interventions and length of follow-up.ResultsA total of 36 eyes affected by AK in 34 patients were identified. There were 26 cases diagnosed early (<30 days) and 10 were diagnosed late (≥30 days). There were 31 (86.1%) cases associated with contact lens (CL). Signs associated with early AK included epithelial infiltrates, while signs of late AK included uveitis, ring infiltrate, endothelial plaque and corneal thinning (p<0.05). Surgical treatment was required in seven cases (19.4%). There were 29 (80.6%) cases that reported improved VA. Median best corrected final VA was worse in patients with late diagnosis (logarithm of minimal angle of resolution (logMAR) 0.5, IQR: 0.2–0.8), compared with patients with early diagnosis (logMAR 0.0, IQR: 0.0–0.3; p=0.01). Late diagnosis was associated with a prolonged disease period.ConclusionAK was an uncommon cause of severe keratitis and was associated commonly with CL. Patients with late diagnosis had worse presenting and final VAs as well as a prolonged disease period, indicating need for early recognition and management.

Full textAbstract:
Abstract Background To investigate the expression of elastin in the conjoint facial sheath (CFS) in patients with severe unilateral congenital blepharoptosis in different age groups. Methods Twenty-seven cases of severe unilateral congenital blepharoptosis (27 eyes) were treated with CFS + LM complex suspension from January 2020 to July 2020. Within that sample, 9 patients were over 18 years old, 9 patients were 13 to 17 years old and 9 patients were 5 to 12 years old. CFS and LM specimens were collected during CFS + LM complex suspension surgery. In the CFS specimens, the elastic fibers were observed by Victoria Blue staining. The elastin expression levels of the three groups of specimens were determined and analyzed by immunofluorescent staining and Western blotting. Results Victoria Blue staining showed that elastic fibers were abundant in CFS tissue. Moreover, immunofluorescent staining showed strong positive expression of elastin in the CFS and LM. Furthermore, in the child group, the Western blot results demonstrated that the expression of elastin was higher in the CFS than in the LM (P < 0.05). Additionally, the expression of elastin was significantly higher in the CFS of children than in that of adults or adolescents (P < 0.001). Conclusions The CFS and LM are rich in elastic fibers and elastin, although elastin expression in the CFS decreases with age. Thus, it is feasible to apply CFS + LM complex suspension to cure severe unilateral congenital blepharoptosis.

AimsTo report 15 cases of intraocular lens (IOL) calcification following intraocular surgery and to identify common risk factors.MethodsA retrospective case review of patients with IOL calcification reported from the Royal Victorian Eye and Ear Hospital, Melbourne, Australia, and six surgeons in private practice in the Australian states of Victoria, New South Wales and Queensland.Results15 cases of IOL calcification were identified. Eight cases were in hydrophilic acrylic IOLs and seven in hydrophilic acrylic IOLs with hydrophobic surface properties. Five cases occurred following intraocular injection of gas during endothelial keratoplasties. Two cases occurred following pars plana vitrectomy where gas was used. The remaining eight cases did not involve the injection of any intraocular gas; six cases were following trabeculectomy surgery, and two cases were after insertion of a ‘piggyback’ sulcus IOL. In each case, the calcification had a characteristic pattern, being centrally placed in the pupillary zone, mainly affecting the anterior lens surface.ConclusionThe aetiology of IOL calcification is not fully understood, although there are known risk factors such as using hydrophilic acrylic materials and the use of intraocular gas. Surgical consideration of a patient’s ocular comorbidities before IOL implantation is an important tool to mitigate some of this risk.

Purpose: To report the visual and refractive outcomes of sequential intracorneal ring segment (ICRS) and toric phakic intraocular lens (IOL) insertion for visual rehabilitation in keratoconus. Methods: A retrospective interventional cohort study was performed through the Corneoplastics unit and Eye Bank, Queen Victoria Hospital, East Grinstead, United Kingdom. Results: 14 eyes of 12 patients had sequential ICRS and phakic IOL implantation for visual rehabilitation of keratoconus between June 2014 and February 2018. After at least 6 months follow-up, the number of eyes with an uncorrected distance visual acuity (UDVA) of 20/40 UDVA or better increased from zero (0%) to 10 (71%). 12 (85.7%) eyes achieved a post-operative UDVA equal to or better than the pre-operative corrected distance visual acuity (CDVA). The number percentage of eyes with a CDVA of 20/40 or better increased from 3 (31%) to 14 (100%). The mean final spherical equivalent improved from −4.07 to −0.17 ( p ⩽ 0.001). The mean refractive astigmatism magnitude improved from 4.76D to 1.23D ( p = 0.002). Seven (50%) eyes had 1.0D or less of refractive astigmatism post-operatively. Conclusion: In this cohort of eyes with keratoconus, sequential ICRS and phakic IOL implantation resulted in excellent visual and refractive outcomes after at least 6 months.
