RESUMEN
PURPOSE: To investigate and compare the anatomic and functional outcomes of chandelier-assisted scleral buckling (CASB) surgery using contact versus non-contact lens-based wide-angle viewing systems (WAVSs) in rhegmatogenous retinal detachment (RRD) patients. METHODS: This was a retrospective, multicenter study evaluating the anatomic (reattachment rate) and visual acuity (VA) outcomes at 6 months post-CASB for primary RRD. RESULTS: Forty-seven RRD patients underwent CASB with a non-contact WAVS (Group C1) and 90 with a contact lens WAVS (Group C2). Preoperative parameters including myopia, macula-off RRD, posterior vitreous detachment, number of retinal breaks, and retinal dialysis as the etiology of RRD did not differ significantly between the two groups. The outcomes of retinal attachment (85.11% of C1 patients and 76.67% of C2 patients, P = 0.34) and final visual outcome (VA ≥6/12: C1 = 61.7%; C2 = 46.67%, P = 0.13) were also comparable. Furthermore, no significant difference in postoperative complications such as cataracts, glaucoma, infection, buckle exposure, and buckle failure was observed. Finally, both groups were comparable in terms of re-detachment rates (10.64% in C1 and 23.33% in C2, P = 0.11). CONCLUSION: The two WAVS approaches used in CASB surgery have comparable surgical and functional outcomes and postoperative complications. The operating surgeon can freely choose between these viewing platforms during the contemporary scleral bucking (SB) surgery without impacting the outcome.

INTRODUCTION: The incidence of post vitrectomy endophthalmitis (PVE) is reported to be between 0.02 and 0.84%. Resterilization of single use instruments is a common practice amidst developing countries to make it more affordable to the patients by reducing the cost of the surgery and also reduce the environmental hazard. The aim of our study is to evaluate the incidence of PVE amidst existing sterilization practices of reused instruments in multiple vitreoretinal centres in India. METHODOLOGY: Centres with an endophthalmitis tracking system were invited to participate in a survey. Twenty-five centres were sent a questionnaire via email. The questionnaire included details about the institution, number of vitrectomies performed in a year, sterilization practices followed pre-operatively, intraoperatively and postoperatively, incidence of endophthalmitis and instrument reuse policies. RESULTS: A total of 29 cases of endophthalmitis were reported out of the 47,612 vitrectomies performed across various centres. The mean incidence of endophthalmitis was 0.06%. There was no difference in the rates of endophthalmitis based on various pre-operative, intraoperative or postoperative prophylactic measures. Nearly 80% of the centres change most of the instruments after every case, while the rest reused. The mean number of times a cutter was being reused until discarded was 4.7. Nearly 76% followed a performance-based protocol, and the remaining 24% had a fixed protocol for the number of times an instrument can be reused before discarding it. CONCLUSION: PVE rates are not significantly different in India despite the multiuse of single use instruments. The purpose of this paper is not to suggest an alternate protocol but to creating one in the future with these results in mind, to rationalise the use of single use instruments, make VR surgery more affordable and also have a positive impact on the carbon footprint of consumables in surgery.

ABSTRACT The objective of this article was to review the disorganization of inner retinal layers as a biomarker in diabetic macular edema. A systematic search was conducted in PubMed®/MEDLINE®, Cochrane and Embase until August 2021. The keywords used were: "disorganization of inner retinal layers (DRIL)", "diabetic macular edema (DME)" and "biomarkers". No restrictions were imposed on the types of study to be included. The studies selected for eligibility were those that included the diagnosis of diabetic macular edema (center involved, resolved), that were well documented with spectral domain optical coherence tomography, that included disorganization of inner retinal layers as one of the reported alterations, with a follow-up of at least 3 months, and those in which the best corrected visual acuity was evaluated pre and post. There were no limitations regarding the type of treatment established. References of identified studies were searched for additional relevant articles. Articles not published in peer review journals were excluded. All studies were evaluated by two investigators independently. When one of them was in doubt, it was assessed by a third evaluator. A total of seven studies were included. Four were retrospective, longitudinal cohort study and three cross-sectional observational. Regarding the population studied, 61.5% were men and 38.4% were women, most of them had diabetes mellitus type 2 (85.8%). Regarding the stage of diabetes, the percentage of patients with mild nonproliferative diabetic retinopathy was 28.2%, with moderate nonproliferative diabetic retinopathy was 28.5%, with severe nonproliferative diabetic retinopathy was 15.9% and with nonproliferative diabetic retinopathy was 27.4%. In 100% of the studies, the diagnosis of diabetic macular edema in the center involved was included by spectral domain optical coherence tomography (Heidelberg). In all the studies, the presence of disorganization of inner retinal layers was recorded and its association with best corrected visual acuity was evaluated. The measurement was carried out using the LogMAR scale. In all the studies, the presence or absence of disorganization of inner retinal layers was associated with the best corrected worse/better final visual acuity using p <0.05 as a statical significance. The disorganization of inner retinal layers as a biomarker and their presence have shown to be important predictors of visual acuity in the future in patients with diabetic macular edema. Histopathological studies are required to understand its mechanism of action.
RESUMO O objetivo deste artigo foi revisar sobre a desorganização das camadas internas da retina como biomarcador no edema macular diabético. Uma busca sistemática foi realizada no PubMed®/MEDLINE®, Cochrane e Embase até agosto de 2021. As palavras-chave utilizadas foram "disorganization of inner retinal layers (DRIL)", "diabetic macular edema (DME)" e "biomarkers". Não foram impostas restrições quanto aos tipos de estudo a serem incluídos. Os estudos selecionados para elegibilidade foram aqueles que incluíram o diagnóstico de edema macular diabético (centro envolvido, resolvido), que foram bem documentados com tomografia de coerência óptica de domínio espectral, que incluíram a desorganização das camadas internas da retina como uma das alterações relatadas, com acompanhamento de pelo menos 3 meses, e aqueles em que a melhor acuidade visual corrigida foi avaliada pré e pós. Não houve limitações quanto ao tipo de tratamento estabelecido. Referências de estudos identificados foram pesquisadas para artigos relevantes adicionais. Foram excluídos os artigos não publicados em revistas de revisão por pares. Todos os estudos foram avaliados por dois investigadores de forma independente. Quando havia dúvida com algum deles, a mesma era avaliada por um terceiro avaliador. Um total de sete estudos foram incluídos. Quatro eram estudos de coorte retrospectivos longitudinais e três eram observacionais transversais. Em relação à população estudada, a proporção de homens foi de 61,5% e de mulheres, 38,4%, a maioria com diabetes mellitus tipo 2 (85,8%). Em relação ao estágio do diabetes, o percentual de pacientes com retinopatia diabética não proliferativa leve foi de 28,2%, retinopatia diabética não proliferativa moderada foi de 28,5%, de retinopatia diabética não proliferativa grave foi de 15,9% e de retinopatia diabética não proliferativa foi de 27,4%. Em 100% dos estudos, o diagnóstico de edema macular diabético no centro envolvido foi incluído pela tomografia de coerência óptica de domínio espectral (Heidelberg). Em todos os estudos, foi registrada a presença de desorganização das camadas internas da retina e avaliada sua associação com a melhor acuidade visual corrigida. A medição foi realizada usando a escala LogMAR. Em todos os estudos, a presença ou ausência de desorganização das camadas internas da retina foi associada a pior/melhor acuidade visual final melhor corrigida usando p<0,05 como significância estática. A desorganização das camadas internas da retina como biomarcador e sua presença têm se mostrado importantes como preditor da acuidade visual no futuro em pacientes com edema macular diabético. Estudos histopatológicos são necessários para entender seu mecanismo de ação.

Proliferative vitreoretinopathy (PVR) is the leading cause of failed rhegmatogenous retinal detachment (RRD) surgery. Based upon the presence of clinical features and due to associated underlying risk factors, it is classified into various grades based upon its severity and extent of involvement. Despite excellent skills, flawless techniques, and high-end technology applied in the management of RRD, PVR still occurs in 5-10% of cases. Due to the advancements in wide angle viewing systems, advance vitrectomy machines and fluidics, early identification, use of long-term heavy silicon oil tamponades, high-speed cutters, small-gauge vitrectomies, use of perfluorocarbon liquid (PFCL), and small-gauge forceps and scissors, the success rate in the management of PVR has increased leading to improved anatomical outcomes. However, functional outcomes do not correlate well with improved anatomical outcomes. Various complications occur after RRD repair that are responsible for re-retinal detachment and recurrence of PVR. This article highlights causes, risk factors, classification, grading, diagnosis, and approach to management of PVR and post-PVR surgery complications.
RESUMEN
PURPOSE: To derive consensus statements for surgical management of proliferative diabetic retinopathy (PDR) for vitreoretinal (VR) surgeons. METHODS: Thirteen prolific VR surgeons representing all regions of India were invited to participate in a 42-point questionnaire based on the Delphi methodology describing various surgical scenarios commonly encountered in PDR. Consensus was derived using predefined robust analytics. Scenarios that returned a moderate consensus in round 1 were taken to round 2 as per the Delphi methodology. After considering all inputs, the final consensus criteria were developed. RESULTS: A strong consensus was derived about waiting for 4 weeks before considering vitrectomy. In treatment-naïve eyes with fresh vitreous hemorrhage (VH), the wait time was slightly shorter for extramacular tractional retinal detachment (2-4 weeks) and longer (4-6 weeks) for eyes treated previously with laser or anti-VEGF agents. The expert panel recommended using preoperative anti-VEGF only in eyes with large membranes requiring extensive dissection. For post vitrectomy VH, while a conservative approach was recommended for the first episode of VH, experts recommended immediate vitreous lavage for recurrent episodes of VH. In eyes with iris neovascularization, the panel recommended immediate anti-VEGF injection followed by early vitreous lavage in nonresponsive eyes. A strong consensus was derived for stopping antiplatelet agents before surgery, while there was only a moderate consensus for performing vitrectomy for recalcitrant macular edema unresponsive to anti-VEGF injections in the absence of traction. CONCLUSION: This study provides valuable consensus on managing the different scenarios encountered during surgical management of PDR and should help guide the VR surgeons in clinical decision-making.

We report a case of bilateral progressive outer retinal necrosis (PORN) in a patient with acquired immune deficiency syndrome with CD4 count 50 cells/µL. He was treated with standard intravenous and intravitreal antivirals but ultimately developed complications such as retinal detachment and epiretinal membrane. His vision was preserved with early pars plana vitrectomy. This case demonstrates that prompt clinical diagnosis of PORN with its successful medical and surgical management can help prevent progression of this frightening disease.
RESUMEN
PURPOSE: The purpose of this study was to evaluate etiologies, management, and outcomes of patients with giant retinal tears (GRTs) undergoing primary surgery at a tertiary referral center. METHODS: This was a retrospective, consecutive case series of 94 patients with at least 3 months follow-up after silicone oil removal (SOR). Fifty-seven eyes (60.6%) underwent vitrectomy, 36 eyes (38.3%) underwent combined vitrectomy with buckling, and 1 eye (1.1%) underwent scleral buckling. Perfluorocarbon liquid (PFCL) heavy liquid to flatten GRT flap intraoperative has been used then PFCL air exchange then air-silicon exchange in all eyes undergoing vitrectomy. Fellow eye was observed for retinal detachment (RD). RESULTS: Idiopathic cause constitutes 47 eyes (50%), in which 25 eyes (26.6%) are myopic and 22 eyes (23.4%) have a history of trauma. Eighty-five eyes (90.4%) achieved anatomic success. Visual acuity at the last follow-up was at least 20/400 in 71 eyes (75.5%) of patients. Recurrent RD after SOR was found in 21 eyes (22.3%), of which 50% had proliferative vitreoretinopathy grade C (PVR-C) or more (P = 0.03) and 20% had GRT size more than 180° (P = 0.04). Pars plana vitrectomy (PPV) alone (P = 0.89) or combined PPV with buckling (P = 0.98) has no significant correlation with recurrent RD. Twenty-one percent of the fellow eye had RD. CONCLUSION: Idiopathic cause constitutes the majority (50%). Patients with GRT who underwent surgery achieved a high anatomic success rate. PVR-C or more and GRT size more than 180° remain the most significant risk factor for recurrent RD after SOR, whereas PPV alone or combined PPV with buckling has no significant correlation with recurrent RD.
RESUMEN
PURPOSE: To evaluate the functional changes on the macula, before and after silicone oil removal (SOR) using microperimetry (MP3) in patients originally operated for macula-off rhegmatogenous retinal detachments. METHODS: Prospective interventional study, N = 20. All cases underwent complete ophthalmic examination, including determination of Snellen best-corrected visual acuity, indirect ophthalmoscopy, and MP3 for measuring retinal sensitivity. Primary outcome measure was to describe the alterations in the retinal sensitivity on the macula after SOR. RESULTS: Mean retinal sensitivity increased in 100% patients (20/20) after SOR with a mean value of 97.44 dB. Best-corrected visual acuity after SOR remained unchanged in 90% (18/20) and improved by 2 lines in only 10% patients (2/20). Median retinal sensitivity of central 6° of the macula was 766.95 ± 173.29 dB before SOR and 863.8 ± 181.08 dB after SOR, P < 0.0001. Mean best-corrected visual acuity was 20/40 before SOR (range, 20/30-20/60) (logarithm of the minimum angle of resolution 0.314 ± 0.169) and 20/40 after SOR (range 20/30-20/80) (logarithm of the minimum angle of resolution 0.315 ± 0.159), P = 0.1628. CONCLUSION: MP3 was found to be a highly sensitive tool in detecting increased retinal sensitivity after SOR, particularly in central 6° of the macula without significant change in best-corrected visual acuity. Hence, MP3 is an important qualitative indicator of visual function.

BACKGROUND: To evaluate the functional long-term outcome in patients with macular oedema (MO) secondary to central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO) treated with dexamethasone implant (DEX implant) and to identify its clinical predictors. METHODS: A 24-month, retrospective, multinational, real-world study. Chart review of patients with either naïve or recurrent MO secondary to CRVO/BRVO treated with DEX implant, including best-corrected visual acuity (BCVA), central subfield thickness (CST), demographic baseline characteristics and details of any additional treatment during follow-up. RESULTS: A total of 155 eyes (65 CRVO, 90 BRVO) from 155 patients were included. At 24 months, mean BCVA did not change significantly in CRVO (-2.1±24.5 letters, p=0.96) and BRVO patients (1.3±27.0 letters, p=0.07). A worse baseline BCVA (p<0.001), visual acuity (VA) gain ≥5 letters at 2 months (p=0.006) and no need for adjunctive intravitreal therapy after first DEX implant (p=0.001) were associated with a better final BCVA gain. Treatment-naïve patients (p=0.006, OR: 0.25, 95% CI 0.11 to 0.57) and those with a baseline CST≤400 µm (p=0.02, OR: 0.25, 95% CI 0.10 to 0.63) were identified as being less likely to need additional intravitreal therapy. CONCLUSION: Clinical baseline characteristics and the early treatment response were identified as possible predictors for long-term outcome and the need of adjunctive intravitreal therapy in MO secondary to BRVO/CRVO treated by DEX implant.

BACKGROUND AND OBJECTIVES: To analyze the panorama optical coherence tomography angiography (P-OCTA) characteristics of serpiginous-like choroiditis (SLC) and to correlate these findings with indocyanine green angiography (ICGA). PATIENTS AND METHODS: Prospective, observational study of 32 eyes of 24 patients. Twenty-seven eyes of 16 patients who met inclusion criteria were included in the final study. Multimodal imaging was performed using P-OCTA, OCT, fundus autofluorescence, fluorescein angiography, and ICGA. Morphologic features at the site of lesions were analyzed using P-OCTA and correlated with ICGA. RESULTS: P-OCTA in active phase revealed areas of large flow void, which correlated with hypofluorescent areas on ICGA. Healing phase revealed appearance of vascular network due unmasking of choriocapillaris that corresponded to reduced hypofluorescence on ICGA. CONCLUSION: P-OCTA as a noninvasive tool provides widefield and high-resolution images that can be used as an complementary tool to ICGA for diagnosis of SLC cases.

PURPOSE: To evaluate and correlate the functional treatment response using microperimetry (MP3) with the morphological findings on optical coherence tomography angiography (OCTA) in wet AMD pre- and post-treatment with anti-vascular endothelial growth factor (VEGF). This was a single-centre prospective, interventional study. METHODS: Patients with wet AMD were treated with 3 injections of intravitreal anti-VEGF at monthly intervals for 3 months and followed at 1, 2, 3, and 6 months postinjection. Using "overlay" features, morphologic characteristics of OCTA at the site of choroidal neovascular membrane (CNVM) lesion were analyzed and correlated functionally with MP3. Data were collected including visual acuity at presentation and follow-up with multimodal imaging features, treatment details, complications (if any), and treatment given for that complication. Descriptive observational analysis and paired t-test was used to compare the appearance of the neovascular network on OCTA imaging with retinal sensitivity on MP3. RESULTS: OCTA in the pretreatment phase revealed CNVM as an abnormal vascular network arising from the choroid and invading the subretinal space. On MP3, decreased retinal sensitivity was observed corresponding to the area of CNVM. Post-treatment, OCTA revealed reduction in abnormal vascular network in 51 (91.07%) eyes that correlated with increased retinal sensitivity at the corresponding area on MP3. Statistical analysis showed baseline mean retinal sensitivity at the site of CNVM as 320.07 dB, which improved to 521.53 and 730.20 dB at 1 and 3 months postinjection follow-up, respectively. CONCLUSION: Combining the findings of OCTA and MP3 using "overlay" features gives us precise information of structure-function correlation at presentation and also in response to treatment. It also helps to improve patient's compliance, confidence to treatment, and their understanding of the disease process as well.

Rhegmatogenous retinal detachment (RRD) repair is one of the most common vitreoretinal surgeries a surgeon performs. In an ideal scenario, RRD can be repaired with a single surgical intervention; however, despite excellent skill, flawless technique, and the introduction of high-end technology, up to 10% of cases require additional interventions to ultimately repair recurrent detachments. It is thus important to study the outcomes of multiple interventions to understand whether performing repeat vitrectomy on patients with a history of failed surgeries is worthwhile. Thus, recurrent retinal detachment (re-RD) remains a significant challenge for vitreoretinal surgeons as well as the patients considering the economic and the emotional burden of undergoing multiple interventions. The advent of microincision vitrectomy system, perfluorocarbon liquids, and effective intraocular tamponades has opened new doors for managing re-RDs. In this article, we have reviewed and summarized the various causes and approaches for management for optimal anatomical and functional outcomes.

CONTEXT: Role of Ozurdex in macular edema due to various posterior segment pathologies. AIM: The aim of this study is to report outcome of Ozurdex implant in macular edema (ME) secondary to various posterior segment pathologies. SETTINGS AND DESIGN: This was a single-center, retrospective, interventional study. SUBJECTS AND METHODS: Patients of ME were treated with one or more Ozurdex implants (0.7 mg). Data collection included demographic details, best-corrected visual acuity (BCVA), central foveal thickness (CFT), duration of efficacy, and record of adverse events (if any) within 24 weeks. STATISTICAL ANALYSIS USED: Paired sample t-test, Stata data analysis, and statistical software, version 12.1, StataCorp, College Station, TX, USA, were used in the study. RESULTS: One hundred and sixteen eyes of 104 patients were studied which had a diagnosis of diabetic ME (n = 46), retinal vein occlusion (n = 40), and uveitis (n = 30). The average age of patients (mean ± standard deviation) was 50.2 ± 21.9 years. Baseline mean ± SD (standard deviation) logMAR BCVA, CFT, and intraocular pressure (IOP) were 0.636 ± 0.4, 527.8 ± 210.1 µm, and 15.3 ± 3.8 mmHg, respectively. The reinjection interval was around 12-18 weeks. Ozurdex proved its efficacy in improving mean logMAR visual acuity and reduction of CFT from baseline till 12 weeks' follow-up period (0.414 ± 0.5 and 301.5 ± 278.5, respectively; P < 0.05), and after 12 weeks' follow-up, it started worsening (0.530 ± 0.9 and 444.8 ± 375.2, respectively; P > 0.05). The most common reported adverse event was significant rise of IOP (>5 mmHg), with a total of 12 cases followed by cataract 9 cases. CONCLUSION: Ozurdex implant leads to a significant improvement in BCVA and CFT values till 12 weeks, followed by a gradual decline for all the pathologies studied together. No new safety concerns were observed with the Ozurdex implant. The duration of efficacy was found to be <24 weeks.
