Purpose: The purpose of this meta-analysis was to compare the efficacy and safety of corticosteroid implant and intravitreal ranibizumab for the treatment of macular edema (ME).
Materials And Methods: PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials were comprehensively searched for studies comparing dexamethasone implant with ranibizumab in patients with ME. Best-corrected visual acuity (BCVA), central subfield thickness (CST), and adverse events were extracted from the final eligible studies. RevMan 5.3 software was used to analyze the data, and the modified Jadad assessment tool was used to access the quality of outcomes.
Results: Three randomized controlled trials (RCTs) were included in our analysis. The types of causes of ME include central retinal vein occlusion (CRVO), branch retinal vein occlusion (BRVO), and diabetic retinopathy (DR). The ranibizumab treatment group had significantly better BCVA compared with the corticosteroid treatment group (standard mean difference [SMD] -0.80; 95% CI -1.08, -0.53; <0.00001). The ranibizumab treatment group also had higher CST reduction compared with the corticosteroid treatment group, and there was a significant difference (weighted mean difference [WMD] 167.58; 95% CI 125.21-209.95; <0.00001). There was no significant difference in serious adverse effects between the two groups (SMD 1.67; 95% CI 0.69, 4.05; =0.26). However, the use of corticosteroid implant had a higher risk of intraocular pressure (IOP) (OR 6.88; 95% CI 4.53-10.44; <0.00001) elevation and cataract (OR 3.98; 95% CI 1.89-8.37; =0.0003) than ranibizumab treatment and fewer injections.
Conclusions: Compared with ranibizumab, corticosteroid implant did not have greater improved BCVA, but corticosteroid implant had less CST reduction. The advantages of corticosteroids are fewer injections, while the advantages of ranibizumab include fewer side effects.

Purpose: Intravitreal injections of anti-VEGF agents are considered as safe, with a very low rate of intraocular inflammations (IOI). Faricimab is a novel intravitreal bispecific antibody targeting both VEGF-A and angiopoietin-Tie2 independently. Despite a safe profile in randomized clinical trials, several real-life studies have reported cases of IOI.

Objective This study aims to evaluate the real-world efficacy of ranibizumab biosimilar (Ongavia), compared to aflibercept (Eylea), in the treatment of treatment-naïve neovascular age-related macular degeneration (nAMD) at a busy tertiary eye care centre. Methods A retrospective analysis of medical records from August 2022 to August 2024 was conducted, comparing treatment outcomes in treatment-naive nAMD patients who received either Ongavia or Eylea intravitreal anti-VEGF (vascular endothelial growth factor) injections under a treat-and-extend protocol. Initial and 12-month outcome measures post-treatment initiation were collected, including best-corrected visual acuity (BCVA), central retinal thickness (CRT), prescribed treatment intervals, actual injection frequency, and the average total number of injections per eye over 12 months.

Purpose: To evaluate changes in the retinal microvasculature using widefield swept-source optical coherence tomography angiography (SS-OCTA) following three anti-vascular endothelial growth factor (anti-VEGF) loading injections for diabetic macular edema (DME).
Methods: Thirty-four treatment-naïve patients with DME received an initial three loading injections, followed by injections on an as-needed basis. Macular ischemia was evaluated based on the foveal avascular zone (FAZ) area, perfusion density, and vessel density on a 3 × 3-mm SS-OCTA image.
