Article Synopsis
  • Choroidal detachment (CD) during retinal detachment surgery can negatively affect surgical results and vision, necessitating specific management techniques.
  • Cannula-guided choroidal drainage is essential for mitigating pre-existing CDs, especially in complex cases with hemorrhagic detachment.
  • Intraoperative sudden CD can be caused by issues like hypotony or air entry from cannula slippage, which may lead to serious complications like Venous Air Embolism (VAE); prompt action to stop air infusion is critical to prevent life-threatening outcomes.

Article Synopsis
  • The study aimed to assess the visual and anatomical outcomes in diabetic macular edema (DME) patients who switched from intravitreal Aflibercept (IVI AFL) to biosimilar Ranibizumab (B-RBZ) due to financial reasons rather than efficacy issues.
  • A total of 57 DME patients were observed, showing substantial improvement in visual acuity during treatment with Aflibercept and a slight decline after switching to Ranibizumab, but overall vision remained better than the initial baseline.
  • The transition maintained anatomical stability in terms of central macular thickness and reduced subretinal and intra retinal fluid levels, indicating that biosimilar Ranibizumab is an effective and cost-efficient therapeutic option

Article Synopsis
  • - This study evaluated the safety and effectiveness of using vancomycin injection as a standard preventive measure during vitreoretinal surgeries, focusing on large-scale application over 70 months.
  • - A total of 31,720 procedures were analyzed, including major, minor, and silicone oil removal surgeries, with no cases of hemorrhagic occlusive retinal vasculitis or bacterial endophthalmitis reported postoperatively.
  • - The findings suggest that using vancomycin in infusion fluid during these procedures is safe and beneficial in reducing the risk of post-surgery bacterial infections.

Purpose: This study investigates the efficacy of transitioning patients with neovascular age-related macular degeneration (nAMD) from aflibercept (T1) to biosimilar ranibizumab (T2), an approach not previously documented in literature.

Methods: In this multicenter observational study, patients over 50 years of age with nAMD were shifted from intravitreal aflibercept (IVI AFL) to biosimilar ranibizumab (B-RBZ) due to financial constraints. This study employed standardized ophthalmological methods to assess visual acuity (VA), central macular thickness (CMT), and subretinal and intraretinal fluid.

Purpose: To assess the safety and efficacy of intravitreal Aflibercept (IVA) versus dexamethasone (DEX) implant for treating recalcitrant diabetic macular edema (DME) in pseudophakic eyes at 1-year follow-up.

Design: Retrospective comparative case series.

Participants: Data of all patients diagnosed with DME between January 2019 and December 2021, who underwent 4-monthly doses of intravitreal ranibizumab but had persistent DME [central macular thickness (CMT) within 10% of baseline value] were extracted from a computerized database.

Closure rate of full-thickness macular holes (FTMHs) with basal diameter >1000 μ is known to be poor. Patients presenting with FTMH having a minimum basal diameter of >1000 μ without any coexistent retinal morbidity were offered vitrectomy, internal limiting membrane peeling, retinal massage, and aspiration of subretinal fluid from the MH. Visual acuity (VA) and spectral-domain optical coherence tomography (SD OCT) assessments were performed at baseline, week 1 after surgery and at postoperative months 1, 3, 6, and 12.

This was a single center, prospective uncontrolled nonrandomized case series. Two eyes with recalcitrant ME secondary to CRVO, who have received a minimum of ten intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections, underwent IVI brolucizumab (BRZ). Patients underwent best corrected visual acuity (BCVA) testing, ophthalmic examination, and optical coherence tomography at baseline and follow-up visits (weeks 4, 8, 12, and 16).

Rhegmatogenous retinal detachment (RRD) following femtosecond laser-assisted cataract surgery (FLACS) has not been reported till date. We described the first case of RRD after FLACS. A 29-year-old male presented with complaints of sudden, painless dimness of vision in the left eye (LE) for the past 2 days.

Purpose: To describe a novel surgical technique to unfold congenital falciform folds.

Method: A retrospective, interventional case series was performed where a novel technique was applied to treat five cases of congenital falciform folds. Twenty-five-gauge vitrectomy was performed along with the removal of all vitreous adhesions.

Background: Falciform folds are congenital tractional retinal folds due to strong contractile forces and hyperextensibility of retina resulting in temporal dragging of the macula and often associated with familial exudative vitreoretinopathy and retinal detachment (RD). Retinologists are reluctant to treat these entities in view of their poor visual recovery.

Purpose: To describe a novel surgical technique to unfold the falciform folds.

Article Synopsis
  • The study compares the effects of innovator ranibizumab (iRBZ) and its biosimilar (bRBZ) on patients with diabetic macular edema (DME) in India, focusing on visual acuity and retinal thickness over 6 months.
  • Data from patients receiving at least three injections of either treatment were analyzed, showing significant improvements in visual acuity and central macular thickness for both groups without significant differences between them.
  • The results indicate that the biosimilar ranibizumab is as effective as the innovator version in treating DME, suggesting it can be a viable alternative in clinical practice.
