Résumé :
Diabetic retinopathy (DR) is a socially significant disease with a steady tendency to increase, in which there is a high risk of disability due to persistent loss of vision. There are three main pathogenetically substantiated methods of DR treatment: laser coagulation of the retina; intravitreal injections of VEGF inhibitors, steroid drugs; vitreoretinal surgery. In the later stages of DR, vitrectomy is the main method of its complications treating, but there is no clear understanding of the timeliness of this operation. The analysis of the results of original research on this problem is carried out. It has been shown that with the advent of new instruments, modified vitrector, operating microscopes, viewing systems and vitreoretinal combines, vitrectomy led to a change in the paradigm of DR treatment. These advances have resulted in better surgical control and greater precision, while at the same time shorter surgical times and fewer surgical complications. There is a tendency to perform vitrectomy at earlier stages of DR, which has a pathogenetic rationale. This could be a leap forward in the treatment of DR as a preventive measure against the development of proliferative DR.

Résumé :
Aim.To evaluate the effectiveness of subconjunctivally injected viscoelastic material (VEM) for the self-sealing of leaking sclerotomy in transconjunctival sutureless vitrectomy (TSV).Methods. This was a prospective interventional series. Subconjunctival injection of VEM was performed in eyes showing leaking sclerotomy at the end of TSV in selected cases. This procedure was performed in 24 consecutive eyes from 24 patients scheduled for 23- or 25-gauge TSV with phacoemulsification for various vitreoretinal diseases combined with cataracts.Results.Among the 24 eyes, 13 cases were scheduled for 23-gauge TSV, while 11 cases were scheduled for 25-gauge TSV. The average number of injection sites per eye was1.7±0.9in the 23-gauge cases and1.5±0.7in the 25-gauge cases. Leakage was most commonly observed at the vitrector site of the sclerotomy, while little leakage was observed at the illuminator site. There were no cases of postoperative hypotony.Conclusion.Subconjunctival injection of VEM was simple and effective for the self-sealing of leaking sclerotomy after TSV in selected cases.

Résumé :
Purpose. To evaluate comparative aspiration flow performance and also vitrectomy operating time efficiency using a double-cutting open port vitreous cutting system incorporated in a two-dimensional cutting (TDC, DORC International) vitrectome design versus standard vitreous cutter.Methods. In vitro investigations compared aspiration flow rates in artificial vitreous humor at varying cutter speeds and vacuum levels using a TDC vitrectome and a standard vitrectome across different aspiration pump systems. A prospective single-centre clinical study evaluated duration of core vitrectomy in 80 patients with macular pucker undergoing 25-gauge or 27-gauge vitrectomy using either a TDC vitrectome at 16,000 cuts per minute (cpm) or standard single-cut vitrectome, combined with a Valve Timing intelligence (VTi) pump system (EVA, DORC International).Results. Aspiration flow rates remained constant independent of TDC vitrectome cut rate, while flow rates decreased linearly at higher cutter speeds using a classic single-blade vitrectome. Mean duration of core vitrectomy surgeries using a TDC vitreous cutter system was significantly (p<0.001) shorter than the mean duration of core vitrectomy procedures using a single-cut vitrectome of the same diameter (reduction range, 34%–50%).Conclusion. Vitrectomy surgery performed using a TDC vitrectome was faster than core vitrectomy utilizing a standard single-action vitrectome at similar cut speeds.

Résumé :
Abstract Background: In current vitrectomy, the surgeon guides the vitrectome and a rigid fiber light guide with one hand each. It would be desirable to have a free hand for other surgical instruments and maneuvers. Methods: In the feasibility study presented here, a 20 gauge vitrectome is equipped with a miniature white LED that could eliminate the need for the separate light guide and therefore free one hand. The functionality of the system is proved in a ping-pong ball filled with agar and an ex-vivo porcine eye. Results: The brightness of the approach appears to be sufficient without any realistic phototoxic retinal hazard while the functionality of the vitrectome, in combination with the LED, is still given. Conclusion: The combination of a 20 gauge vitrectome with a LED illumination unit was successfully tested. The approach can be transferred to small vitrectomes in the future

Résumé :
A vitrectome is a commonly used instrument in eye surgery, which is used to cut and aspirate the vitreous body out of the eye. The mechanism of the vitrectome consists of miniature components that need to be assembled by hand due to their size. Non-assembly 3D printing, in which fully functional mechanisms can be produced in a single production step, can help create a more streamlined production process. We propose a vitrectome design based on a dual-diaphragm mechanism, which can be produced with minimal assembly steps using PolyJet printing. Two different diaphragm designs were tested to fulfill the requirements of the mechanism: a homogenous design based on ‘digital’ materials and a design using an ortho-planar spring. Both designs were able to fulfill the required displacement for the mechanism of 0.8 mm, as well as cutting forces of at least 8 N. The requirements for the cutting speed of the mechanism of 8000 RPM were not fulfilled by both designs, since the viscoelastic nature of the PolyJet materials resulted in a slow response time. The proposed mechanism does show promise to be used in vitrectomy; however, we suggest that more research into different design directions is required.

Résumé :
Abstract Context.—Determining the most significant prognostic variables in uveal melanoma is important for stratifying patients for metastasis surveillance and possible initiation of chemotherapy or immunotherapy. Monosomy 3, one such variable, can be determined using fluorescence in situ hybridization, either on enucleated samples, fine-needle aspiration biopsy, or tumor sample obtained by vitrector. Objective.—To evaluate possible regional discordance in chromosome 3 by sites likely to be sampled by different biopsy methods. Design.—Eighteen consecutive patients with uveal melanoma who underwent primary enucleation were studied. Representative paraffin blocks were selected based on review of hematoxylin-eosin stained sections, and the apex and base of each tumor was demarcated. Unstained paraffin sections, 4 μm in thickness, were prepared, and fluorescence in situ hybridization, looking for monosomy 3, was performed. The chromosomal analysis was also correlated with histologic evaluation for melanoma cell type (spindle vs epithelioid cell), ciliary body involvement, presence of positive periodic acid–Schiff vascular mimicry patterns, scleral or extrascleral spread and size. One case was excluded because of necrosis. Results.—Ten of the 17 remaining cases (59%) demonstrated monosomy 3 (in either the base or both base and apex of the tumor) with 7 cases (41%) showing disomy. Seven cases (70%) with monosomy 3 demonstrated this in both the apex and the base locations, whereas 3 cases (30%) showed monosomy in one location only (always at the base). Fourteen of the 17 cases (82%) revealed concordance in chromosome 3–monosomy 3 (7 of 14, 50%) or chromosome 3–disomy 3 (7 of 14, 50%). All 3 discordant cases demonstrated the monosomy 3 at the base with disomy at the apex. Lack of concordance between the base and apex did not correlate with melanoma cell type. Conclusions.—Prognostic variables are important in management of neoplasms, and this study points out that the site of tissue biopsy for prognostication in uveal melanoma could affect the results obtained, at least for the presence of monosomy 3.

Résumé :
Purpose. To evaluate whether limited vitrectomy is as effective as complete vitrectomy in eyes with epiretinal membrane (ERM) and to compare the surgical times and rates of complications. Methods. In this multicentre European study, data of eyes with ERM that underwent vitrectomy from January 2017 to July 2018 were analyzed retrospectively. In the limited vitrectomy group, a posterior vitreous detachment (PVD) was induced up till the equator as opposed to complete PVD induction till the vitreous base in the comparison group. Incidence of iatrogenic retinal breaks, retinal detachment, surgical time, and visual outcomes were compared between groups. Results. We included 139 eyes in the analysis with a mean age being 72.2 ± 6.9 years. In this, sixty-five eyes (47%) underwent limited vitrectomy and 74 eyes (53%) underwent complete vitrectomy. Iatrogenic retinal tears were seen in both groups (5% in limited vitrectomy versus 7% in complete vitrectomy, p = 0.49 ). Retinal detachment occurred in 2 eyes in the limited vitrectomy group (3%) compared to none in the complete vitrectomy group ( p = 0.22 ). Best-corrected visual acuity (BCVA) and central macular thickness improved significantly with no intergroup differences ( p = 0.18 ). Surgical time was significantly shorter in the limited vitrectomy group with 91% surgeries taking less than 1 hour compared to 71% in the complete vitrectomy group ( p < 0.001 ). Conclusion. A limited vitrectomy is a time-efficient and effective surgical procedure for removal of epiretinal membrane with no additional complications.

Résumé :
Purpose. To demonstrate the long-term effectiveness of vitrectomy for intermediate uveitis (IU) and to determine whether complete control of inflammation before vitrectomy is necessary.Methods. This retrospective study included 66 eyes of 66 patients with IU who underwent vitrectomy for vitreoretinal complications. Eyes were followed for at least 12 months after vitrectomy. The degree of inflammation control and visual acuity were compared before and after vitrectomy. These parameters were compared according to the presence of complete inflammation control before surgery.Results. The indications of vitrectomy included epiretinal membrane (26 eyes), vitreous opacity (21 eyes), and tractional retinal detachment (12 eyes), among others. Uveitic attacks did not occur in 44 of the 66 patients after vitrectomy. The numbers of uveitis attacks, local steroid injections, and systemic medications significantly decreased, and vision meaningfully improved after vitrectomy. These parameters did not differ significantly, regardless of the presence of preoperative inflammation.Conclusions. This study showed that vitrectomy is a good modality to manage vitreoretinal complications associated with IU, even if complete control of intraocular inflammation is not achieved before vitrectomy.

Résumé :
Abstract Purpose To compare the efficacy and safety of core vitrectomy and pars plana vitrectomy for lens exchange in patients with intraocular lens dislocation. Methods This is a retrospective study conducted at one eye center in Zurich, Switzerland. We reviewed 124 eyes with dislocated intraocular lens undergoing lens exchange carried out by two surgeons between 03/2016 and 12/2019 (45 months). Intraocular pressure (IOP) and best-corrected visual acuity (BCVA) were analyzed preoperatively and at 5 time points up to 12 months after lens exchange. Data on postoperative complications were collected. Results There were 124 eyes with intraocular lens dislocation that were referred for lens exchange. Of these eyes, 59 (48%) received core vitrectomy and 65 (52%) received pars plana vitrectomy with lens exchange. Glaucoma was more frequent in the core vitrectomy group (78%) than in the pars plana vitrectomy group (32%; p < 0.001). In the core vitrectomy group, 19 (32%) eyes presented with visual impairment, 17 (29%) eyes presented with high IOP alone, and 23 (39%) eyes presented with both at the same time prior to surgery. Mean preoperative IOP in the core vitrectomy group decreased from 22.4 ± 9.2 mmHg to 14.7 ± 3.1 mmHg 12 months after surgery (p < 0.001). Mean BCVA changed from 0.40 ± 0.41 logMAR preoperatively to 0.32 ± 0.37 logMAR at 12 months postoperatively (p = 0.598) in the core vitrectomy group. In the pars plana vitrectomy group, 44 (68%) eyes presented with a change in vision, 7 (11%) eyes presented with high IOP alone, and 14 (22%) eyes presented with pressure elevation and visual impairment at the visit prior to surgery. Mean preoperative IOP in the pars plana vitrectomy group decreased from 20.9 ± 8.3 mmHg to 15.1 ± 3.5 mmHg at 12 months after lens exchange (p < 0.001). Mean BCVA in the pars plana vitrectomy group was 0.57 ± 0.62 logMAR preoperatively and 0.22 ± 0.35 logMAR 12 months postoperatively (p < 0.001). Postoperative pressure decompensation occurred more frequently in the core vitrectomy group (20%) than in the pars plana vitrectomy group (6%; p = 0.018). There was no statistically significant difference for postoperative cystoid macular edema (p = 0.055), anisometropia (p = 0.986), and high astigmatism (p = 0.362).

Abstract Purpose To compare the efficacy and safety of core vitrectomy and pars plana vitrectomy for lens exchange in patients with intraocular lens dislocation. Methods This is a retrospective study conducted at one eye center in Zurich, Switzerland. We reviewed 124 eyes with dislocated intraocular lens undergoing lens exchange carried out by two surgeons between 03/2016 and 12/2019 (45 months). Intraocular pressure (IOP) and best-corrected visual acuity (BCVA) were analyzed preoperatively and at 5 time points up to 12 months after lens exchange. Data on postoperative complications were collected. Results There were 124 eyes with intraocular lens dislocation that were referred for lens exchange. Of these eyes, 59 (48%) received core vitrectomy and 65 (52%) received pars plana vitrectomy with lens exchange. Glaucoma was more frequent in the core vitrectomy group (78%) than in the pars plana vitrectomy group (32%; p < 0.001). In the core vitrectomy group, 19 (32%) eyes presented with visual impairment, 17 (29%) eyes presented with high IOP alone, and 23 (39%) eyes presented with both at the same time prior to surgery.

Résumé :
Objective. To investigate the pre- and postsurgical clinical characteristics and clinical efficacy of patients with uveitis. Methods. The clinical data of patients with uveitis who underwent vitrectomy in our hospital from March 2019 to February 2021 were retrospectively analyzed. There were 52 cases of 64 eyes in total. The data on patient’s gender, age, etiology, course of disease, anatomical classification, number of recurrences, changes in vision before and after surgery, changes in eye signs before and after surgery, and occurrence of postoperative complications were collected. The clinical features before and after vitrectomy were compared, and the influencing factors of clinical efficacy were analyzed. Results. The ocular signs of patients with uveitis after vitrectomy were significantly improved compared with before operation, and the difference was statistically significant ( P < 0.05 ). The visual acuity after vitrectomy in patients with uveitis was significantly improved compared with that before operation, and the difference was statistically significant ( P < 0.05 ). There was no significant difference in the surgical treatment of uveitis patients of different gender, age, and etiology ( P > 0.05 ). There are significant differences in the clinical efficacy of vitrectomy in patients with different anatomical classifications. Among them, patients with panuveitis have the best clinical efficacy with vitrectomy and patients with posterior uveitis have the worst clinical efficacy with vitrectomy ( P < 0.05 ). There is a significant difference in the clinical efficacy of vitrectomy in patients with recurrence times. The lower the number of recurrences, the better the clinical efficacy of vitrectomy in patients ( P < 0.05 ). Conclusion. There are significant differences in the clinical signs of patients with uveitis before and after vitrectomy. Vitrectomy is effective in the treatment of uveitis. The type of anatomy and the number of recurrences are influencing factors for the clinical efficacy of vitrectomy. For patients with posterior uveitis, the surgical method should be carefully considered or a more reasonable treatment method should be selected, and for patients with uveitis with less recurrence, vitrectomy should be considered for active treatment.

For the study, 15 patients with 15 eyes were selected with a diagnosis of penetration injury (scleral or corneoscleral) within the boundaries of the flat part of the ciliary body, hemophthalmos without retinal detachment and lens damage. All patients underwent vitrectomy for hemophthalmos. The patients were divided into 3 groups: 1 group of 5 people – vitrectomy was performed on the 2 nd day after admission to the ophthalmology department (primary surgical treatment of pan + vitrectomy); 2 group of 5 people – vitrectomy was performed 12-14 days after primary surgical treatment; 3 group of 5 people – vitrectomy was performed after 1 month or more after a penetrating wound. Results. The optimal timing of vitrectomy in penetrating wounds of the eyeball complicated by hemophthalmos, without the presence of retinal detachment and damage to the lens, has been determined. Conclusion. The analysis of the results of surgical treatment indicates the need for a comprehensive examination of patients with penetrating eye wounds. It is necessary to refrain from early vitrectomy, it is also dangerous to have a blood clot in the vitreal cavity for a long time due to the traction effect on the retina.

Résumé :
Introduction: Surgical approach in vitreous hemorrhage (VH) secondary to diabetic retinopathy remains the procedure of choice for non-clearing VH. However, the most appropriate timing of vitrectomy is yet to be defined. With improvements in surgical techniques, it is reasonable to operate on such patients that have no spontaneous improvement. Objective: To compare the characteristics between groups of patients who underwent immediate and delayed vitrectomy for the management of vitreous hemorrhage due to proliferative diabetic retinopathy (PDR). Methods: Retrospective review of 35 patients who underwent vitrectomy for VH secondary to PDR. Patients were excluded if they had prior vitrectomy, follow up < 1 month post-operatively, other retinal pathology, VH secondary to other causes, uveitis, or advanced glaucoma. Primary outcome was visual acuity in patients receiving immediate (< 30 days) versus delayed (> 30 days) vitrectomy. Secondary analyses included post-surgical complications. Results: 35 eyes were included, 13 eyes had immediate vitrectomy while 22 eyes had delayed vitrectomy. There was no difference between the groups in terms of age, gender, diabetes control, or diabetes duration. Pre-operative and final visual acuities were evaluated, including 7 days, 30-days and 3-months in both Groups. Complications within 3 months were dominantly seen in the delayed vitrectomy Group. Conclusion: Immediate vitrectomy for VH due to PDR decreases time spent with vision loss, and decreases post-surgical complications. Modern vitrectomy surgery is safe and may be considered earlier in VH management.

Résumé :
Purpose:а comparison of the results of epimacular fibrosis surgical treatment with vitrectomy and without it.Patients and methods. Two groups of patients with epimacular fibrosis have been compared. The first group — 20 patients (20 eyes), epiretinal membrane was removed without vitrectomy. The second group (30 patients — 30 eyes), epiretinal membrane was removed after subtotal vitrectomy. Control of visual acuity was monitored, as well as intraocular pressure, the retinal thickness in the Central zone, and the thickness of the nerve fiber layer of the retina in different sectors. Sensitivity of the retina macular zone was determined by using microperimetry Maia, and peripheral zones were determined with the help of computer perimeter, Humpfrey. The patients were examined before surgery and at 1, 3, 6 and 12 months after it.Results. The average duration of surgery was 8 minutes in a group without vitrectomy and 32 minutes in a group of subtotal vitrectomy. 6 patients from 20 in the group of ERM removal without vitrectomy had a relapse of fibrosis found in terms of 3 to 6 months. The groups showed a comparable improvement in visual acuity and photosensitivity of the central retina, as well as a decrease of retina thickness. There was a significant increase in IOP by 1.6 mmHg in the group of subtotal vitrectomy. Statistically significant changes in the retinal nerve fiber layer thickness were recorded only in temporal sector, and they were significantly more pronounced in subtotal vitrectomy group (–15.95 and –22.47 microns respectively). In absolute terms, the decrease in the sensitivity of the peripheral zone of retina was more pronounced in the group of subtotal vitrectomy, intergroup differences were reliable.Conclusion.Direct comparison of the two methods demonstrated their comparable effectiveness in terms of influencing the visual acuity and light sensitivity of the macula. Remove the ERM without vitrectomy does not affect the peripheral visual field and intraocular pressure, in contrast to the removal of the ERM after Subtotal vitrectomy. ERM removal without vitrectomy entails a high risk of recurrence, which indicates significant limitations of intervention and the impossibility of widespread use of this method.

Résumé :
Purpose: To assess the alterations in conjunctival impression cytology following 23-gauge transconjunctival sutureless versus conventional pars plana vitrectomy. Patients and Methods: Sixty consecutive patients were enrolled in the study. Conjunctival impression cytology was performed on 30 eyes (of 30 subjects) with 23-gauge transconjunctival sutureless vitrectomy and on 30 eyes (of 30 subjects) with conventional vitrectomy. Conjunctival impression cytology was performed preoperatively on the 1st day and in the 3rd month after the surgery. Impression cytology specimens of each group were graded and scored using a range of 0-3 according to Nelson's method. Results: In the conventional pars plana vitrectomy group, statistically significant alterations in the conjunctival impression cytology were detected on the 1st postoperative day (p = 0.001) and in the 3rd postoperative month (p = 0.001), whereas in the 23-gauge transconjunctival sutureless pars plana vitrectomy group, statistically significant changes were observed on the 1st postoperative day. However, no significant changes were observed in the following 3 postoperative months (p = 0.08). Conclusion: The properties of impression cytology were altered in the early postoperative period after sutureless and conventional vitrectomy. These changes were improved in the sutureless vitrectomy group only. Sutureless vitrectomy also had an advantageous effect on the conjunctival cytological changes and conjunctival structure.

Résumé :
The study’s purpose was to determine the incidence, risk factors, and outcomes of tractional macular detachment after anti-vascular endothelial growth factor (VEGF) pretreatment before vitrectomy for complicated proliferative diabetic retinopathy. Patients who underwent primary vitrectomy for complicated proliferative diabetic retinopathy, from January 2012 to 31 December 2018, were enrolled. Ophthalmic and pre-operative data were extracted from electronic record systems. All eyes with a valuable Optical Coherence Tomography (OCT)performed within 5 days before injection of anti-VEGF and on the day of vitrectomy were included. Multivariable logistic regression showed that significant risk factors for developing tractional macular detachment included days between anti-VEGF and vitrectomy (OR, 0.71 [95% CI 0.65–0.76]; p < 0.001), vitreous hemorrhage (OR, 0.23 [95% CI 0.11–0.49]; p < 0.001), and age (OR, 1.05 [95% CI 1.02–1.08]; p < 0.001). Decision-tree analysis showed that the stronger predictors of tractional macular detachment were the time between anti-VEGF injection and vitrectomy (p < 0.001). Secondary predictors were the presence of vitreous hemorrhage (p = 0.012) in eyes that underwent vitrectomy between 6 and 10 days after anti-VEGF injection and younger age (p = 0.031) in eyes that underwent vitrectomy 10 days after anti-VEGF injection. Tractional macular detachment occurs in 10% of eyes after anti-VEGF injection, the main risk factors being days between anti-VEGF injection and vitrectomy, vitreous hemorrhage, and age.

To explore the perioperative nursing methods and clinical effects of vitrectomy under ophthalmoscope in the treatment of severe ocular rupture, this study reviews the clinical effects of vitrectomy in the treatment of severe ocular trauma in China, analyzes the perioperative nursing of vitrectomy for ocular trauma under the guidance of an ophthalmoscope, and analyzes the importance of stage I debridement and suture, the choice of operation time, and the advantages of vitrectomy and perioperative nursing care. The retrospective analysis of these data shows that the clinical effect of peri-vitrectomy for ocular trauma under the guidance of an ophthalmoscope is accurate, and surgical treatment should be carried out as soon as possible according to the patient’s condition, which can reduce the complications of suppurative ophthalmitis, eyeball atrophy, and vitreous rebleeding. Perioperative nursing intervention is beneficial to the recovery of visual acuity in patients with severe ocular rupture treated by vitrectomy under the ophthalmoscope, which is worthy of clinical promotion.

Résumé :
Aim:To review the literature relating to diabetic vitrectomy, providing an update on topics where new information is available.Method:Reference to articles in peer-reviewed journals, the minutes of international academic meetings and authoritative textbooks.Results:We discuss aspects of management that will assist the vitreoretinal surgeon in evidence-based decision-making, including indications and timing of surgery, the use of pharmacological adjuvants, the influence of lens status, choice of vitrectomy gauge and the use of tamponades.Conclusions:Improvements in safety and outcome from diabetic vitrectomy have led a trend towards earlier surgery. A growing body of evidence supports the role of vitrectomy in diabetic macular oedema in the presence of traction. Anti-vascular endothelial growth factor (anti-VEGF) may aid surgery, but the risk of progression of tractional retinal detachment should be considered. The evidence for the efficacy of other adjuvants is discussed. We examine the role of cataract surgery in diabetic vitrectomy, discuss the use of tamponades and recommend a pragmatic approach when selecting a vitrectomy gauge.
