Objectives: There have been reports of unexplained visual loss following intra-ocular silicone oil (SiO) tamponade in retinal detachment patients, yet the underlying mechanism is unknown. The aim of this study was to investigate the mechanisms behind retinal toxicity following intra-ocular SiO tamponade in retinal detachment patients.Methods and Results: Vitreous fluid samples were acquired from 27 patients (27 eyes). Twelve eyes for data-independent acquisition (DIA) were divided into four groups: pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RD group), SiO removal after successful retinal reattachment (SO group), cataract surgery after successful retinal reattachment with sterilized air tamponade (FA group), and PPV for epiretinal membrane (ERM group). The remaining 15 eyes were used for enzyme-linked immunosorbent assay analysis. DIA was combined with two-dimensional liquid chromatography–tandem mass spectrometry to find expression changes in the proteome of vitreous. Mean number mass spectra, statistically differentially expressed proteins, gene ontology (GO), pathway representations, and protein interactions were analyzed. GO analysis showed that the protein categories of synapse organization, cell adhesion, and regulation of cell migration in the SO group were differentially expressed compared to the control or FA groups (p < 0.05). Through Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, lysosome and cell adhesion were found to be significantly enriched in the SO group compared to the FA and control groups (p < 0.05). Cadherin 2, transferrin, and lysosome function may partially contribute to silicone oil-related vision loss.Conclusion: Vision loss-inducing novel molecular signatures and pathways that may be associated with SiO toxicity were identified. Transferrin may be a potential visual outcome biomarker for SiO tamponade.

The purpose of this case report is to describe a modified technique involving the use of an autologous neurosensory retinal free flap for closure of a macular hole (MH) during retinal detachment (RD) surgery. A 50-year-old female presented with sudden vision loss (light perception only) and a recurrent myopic RD associated with an MH. An autologous neurosensory retinal free flap was obtained and moved toward the MH. Silicone oil was used as an endotamponade and removed after 6 months. Two months after oil removal visual acuity improved to 20/400 and remained stable thereafter; however, the patient developed central retinal atrophy. One year after surgery the MH was closed and the retina attached. This modified technique with the use of an autologous neurosensory retinal flap provides an alternative approach for recurrent MH in RD procedures.

Purpose The goal of this study was to identify risk factors for redetachment and/or a worse visual outcome after silicone oil removal (SOR) for complicated retinal detachment. Methods The authors retrospectively analyzed 287 consecutive eyes with SOR between January 1999 and December 2003. Results Anatomic success after SOR was achieved in 81% of the eyes. The overall anatomic success at the end of follow-up was 94%. Postoperative ocular hypertension was found in 8% of the eyes, hypotony in 6% of the eyes, and keratopathy in 29% of the eyes. After SOR 43% of the eyes had an improvement in visual acuity of at least two Snellen lines. After multivariate analysis, male sex, the presence of preoperative rubeosis, and proliferative diabetic retinopathy (PDR) were found to be risk factors for recurrent retinal detachment. Male sex, preoperative visual acuity of <0.1 Snellen lines, PDR, the performance of three more operations, any size of retinectomy, and hypotony were found to be associated with a poor visual outcome of Snellen visual acuity <0.1. Conclusions Retinal detachment after SOR in the current unselected series of eyes occurred in approximately 20%, which is comparable to the Silicone Oil Study reports, published approximately 20 years ago. However, preoperative selection was then made, and less than 50% of the silicone oil-filled eyes had SOR. The higher overall anatomic success in the current study may be due to improved vitreoretinal surgical techniques.

Background. The method of the use of autologous conditioned platelet rich plasma is a promising method in the surgery of retinal pathology, particularly in the surgery of rhegmatogenous retinal detachment without the use of additional endolaser photocoagulation, but requires the foundation of its efficiency.Aim: to evaluate the effectiveness of the surgery of rhegmatogenous retinal detachment with central (macular) and peripheral retinal tears, including retinal abruption from the dentate line, with the use of 25, 27-gauge subtotal vitrectomy, pneumoretinopexy and silicone oil tamponade with blocking of retinal defect with the use of autologous conditioned plasma without the use of endolaser photocoagulation around retinal defects.Materials and methods. The surgery included 25, 27-gauge vitrectomy, posterior hyaloid membrane removal, internal limiting membrane removal in case of macular hole, pneumoretinopexy, instiilation in 2–3 layers of autologous conditioned platelet rich plasma, devoid of leukocytes and containing 1.5–3 times more thrombocytes than in whole blood into the area of retinal detachment or along the edge of retinotomy till the retinal defect and nearby intact retina are totally covered. A total of 29 patients with visual acuity from 0.03 to 1.0 underwent the surgery.Results. In the early postoperative period (up to 1 month) 96.6 % of patients showed total retinal reattachment, retinal detachment was blocked, in one patient with multiple retinal tears recurrent retinal detachment was detected; in the early delayed postoperative period (1–3 months) 82.8 % of patients showed total retinal reattachment, in 5 patient retinal reattachment was partial.In the late postoperative period (4–12 months) 86.2 % of patients showed total retinal reattachment, there were 4 recurrent retinal detachments. Patients with recurrent retinal detachment were successfully reoperated. Autologous conditioned plasma was not used during reoperations. Visual acuity of the patients, which underwent surgery in the late postoperative period, was 0.1–1.0.Conclusions. 25, 27-gauge vitreoretinal surgery of rhegmatogenous retinal detachment with central and peripheral retinal tears, including tears with abruption from the dentate line and retinal defects blocking with the use of autologous conditioned plasma rich with thrombocytes without the use of endolaser photocoagulation around retinal defects – is a method which allows to achieve in most cases total retinal reattachment, better functioning of the operated eye.

Background/aimsTo compare risk factors for poor visual outcomes in patients undergoing primary rhegmatogenous retinal detachment (RRD) repair and to develop a scoring system.MethodsAnalysis of the Primary Retinal detachment Outcomes (PRO) study, a multicentre interventional cohort of consecutive primary RRD surgeries performed in 2015. The main outcome measure was a poor visual outcome (Snellen VA ≤20/200).ResultsA total of 1178 cases were included. The mean preoperative and postoperative logMARs were 1.1±1.1 (20/250) and 0.5±0.7 (20/63), respectively. Multivariable logistic regression identified preoperative risk factors predictive of poor visual outcomes (≤20/200), including proliferative vitreoretinopathy (PVR) (OR 1.26; 95% CI 1.13 to 1.40), history of antivascular endothelial growth factor (VEGF) injections (1.38; 1.11 to 1.71), >1-week vision loss (1.17; 1.08 to 1.27), ocular comorbidities (1.18; 1.00 to 1.38), poor presenting VA (1.06 per initial logMAR unit; 1.02 to 1.10) and age >70 (1.13; 1.04 to 1.23). The data were split into training (75%) and validation (25%) and a scoring system was developed and validated. The risk for poor visual outcomes was 8% with a total score of 0, 17% with 1, 29% with 2, 47% with 3, and 71% with 4 or higher.ConclusionsIndependent risk factors were compared for poor visual outcomes after RRD surgery, which included PVR, anti-VEGF injections, vision loss >1 week, ocular comorbidities, presenting VA and older age. The PRO score was developed to provide a scoring system that may be useful in clinical practice.

Introduction: Pars plana vitrectomy in combination with intraocular tamponade with silicone oil is a standard technique in the treatment of complex retinal detachment. Although the use of silicone oil has improved the results of retinal detachment surgery, its removal is recommended due to the ocular complications related to its long term use. However, retinal redetachment can occur after silicone oil removal. Objective: To evaluate the anatomical and visual outcome after silicone oil removal (SOR) in eyes with complicated retinal detachment. Material and Methods: We retrospectively analyzed 64 eyes of 64 consecutive patients of silicone oil removal over a period of 12 months. All eyes had undergone standard 3 ports pars plana vitrectomy with silicone oil placement for complicated retinal detachment. Cases that completed at least 1 month follow up duration after SOR were included in the study. Anatomical success after SOR was achieved in 56 of 64 eyes (87.5%). Seven of 8 redetachments (87.5%) were seen in eyes with silicone oil tamponade duration of less than 6 months. Visual acuity improved or was stabilized in 49 of 64 eyes (76.6%). Using paired T-test, it was found that there was no significant difference in pre and post SOR visual acuity. Postoperative ocular hypertension, corneal decompensation, band shaped keratopathy and hypotony was observed in 9.4%, 4.7%, 6.4% and 21.9% respectively. Conclusion: Although there was no significant improvement in visual acuity, redetachment and complication rates were comparable to other studies. The duration of endotamponade was not significantly associated with the redetachment rate. Key words: Silicone oil removal, Redetachment, Visual outcome, Keratopathy, ocular hypertension.

Purpose. To assess the anatomical and functional outcomes of intravitreal infusion of methotrexate (MTX) during pars plana vitrectomy (PPV) for proliferative vitreoretinopathy (PVR) associated with rhegmatogenous retinal detachment (RRD). Methods. Comparative interventional nonrandomized study including consecutive patients who had vitrectomy for RRD. The study included six groups. Groups I (established PVR), II (high risk of PVR), and III (no risk of PVR) comprised prospectively recruited study eyes, which received PPV and adjuvant intravitreal MTX infusion equivalent to 400 μg/0.1 mL. Groups IA, IIA, and IIIA comprised retrospectively recruited control groups. Main outcome measures were retinal reattachment at the end of 6 months, visual outcome, and complications. Chi-square test or Fisher’s exact test analyzed categorical variables. ANOVA test and Kruskal–Wallis test analyzed quantitative variables. Mann–Whitney U-test and independent t-test evaluated the difference between each group and its control. Comparison between two paired groups was done by Wilcoxon Rank test. The Kaplan–Meier method was used for survival analysis and the log-rank test estimated differences in event-free survival across the groups. P was significant at <0.05. Results. The study included 190 eyes of 188 patients. Study Groups I, II, and III included 42, 35, and 24 eyes, respectively. Mean age was 45 years. Male gender constituted 70% of patients. Mean follow-up period was 6 months. Control Groups IA, IIA, and IIIA included 30, 30, and 29 eyes, respectively. Mean age was 50 years. Male gender constituted 50%. Mean follow-up period was 7 months. Median rate of retinal reattachment was 82% in the study eyes versus 86% in the control eyes. The difference in the retinal reattachment rates between each study group and its respective control was not statistically significant, Group I-IA p =   0. 2 , Group II-IIA p = 0.07 , and Group III-IIIA p = 0.07 . BCVA improved by a mean of 4 lines in the study eyes versus 3 lines in the control eyes. The difference in visual outcome between each study group and its respective control was statistically significant between Groups II-IIA and III-IIIA, p = 0.03 , but not between Groups I-IA, p = 0.07 . We did not detect complications attributed to MTX use in the study eyes. Conclusion. Intravitreal infusion of MTX during PPV is a safe adjuvant therapy in RRD patients with and without PVR. MTX yields superior functional outcomes in patients at high risk of PVR and in patients with no risk of PVR compared to PPV without MTX, but not in cases with established PVR. MTX did not confer an additional advantage in terms of retinal reattachment rate. Summary. Proliferative vitreoretinopathy is a major cause of failure in surgery for rhegmatogenous retinal detachment. Methotrexate as an adjuvant therapy blocks essential drivers in the pathogenetic cascade leading to PVR. Intravitreal infusion has the advantage of blocking the pathology in its nascence and obviates the need for repeated intravitreal injections of the drug.
