Background And Objective: To compare efficacy of monthly treatment with bevacizumab or ranibizumab for macular edema due to retinal vein occlusion.
Patients And Methods: Randomized, multicenter, comparative trial (ClinicalTrials.gov identifier: NCT01428388). Participants were randomized 1:1 to receive monthly treatment with bevacizumab or ranibizumab. The primary outcome was change in central foveal thickness at 6 months compared to baseline.
Results: The trial randomized 98 patients to treatment with bevacizumab or ranibizumab. At 6 months, there were no differences in change in central foveal thickness between groups (bevacizumab: mean reduction of 212.6 µm, 95% confidence interval [CI], -288.3 to -137.0; ranibizumab: mean reduction of 243.8 µm, 95% CI, -309.6 to -178.0; P=.72, analysis of variance [ANOVA]). Both groups showed similar functional outcomes (bevacizumab: 0.33 logMAR gain, 95% CI, -0.47 to -0.18; ranibizumab: 0.34 logMAR gain, 95% CI, -0.45 to -0.23; P=.38, ANOVA).
Conclusion: In the treatment of retinal vein occlusion, bevacizumab and ranibizumab have similar effects on reducing macular thickness and improving visual acuity.

Background/objectives: The visual acuity (VA) outcomes after the first and second years of anti-vascular endothelial growth factor (anti-VEGF) treatment in patients with diabetic macular oedema (DMO) were evaluated, and the factors associated with treatment success were investigated.
Methods: Using Medisoft electronic medical records (UK), this retrospective cohort study analysed VA outcomes, changes, and determinants in DMO patients at year 1 and year 2 after initial anti-VEGF injection. Descriptive analysis examined baseline demographics and clinical characteristics, while regression models were used to assess associations between these factors and changes in VA.

Age-related macular degeneration (AMD) is one of the leading causes of central vision loss in the elderly population. Bevacizumab, a full-length humanized monoclonal anti-VEGF antibody, is commonly used off-label drug to treat AMD. However, the dosing regimen of bevacizumab and other anti-VEGF antibodies requires monthly intravitreal injections followed by regular intravitreal injections at 4-16-week intervals.

Background: The principal objective of our study is to evaluate the characteristics of babies with type 1 ROP, screening practices and treatment trends in a tertiary care centre in Pakistan.
Methods: This prospective study at Mayo Hospital, Lahore (July 2022-July 2024), included 89 preterm infants with type 1 ROP, selected using non-probability sampling. Infants were categorized based on international (GA < 32weeks or BW < 1500 g) and local screening criteria (GA < 35 weeks or BW < 2000 g), and treatment outcomes were evaluated across three groups: Anti-VEGF, combination therapy (Anti-VEGF followed by laser), and laser therapy.

Background: Choroidal neovascular membranes (CNVM) associated with optic nerve head drusen (ONHD) are rare but vision threatening. A variety of treatments, including laser photocoagulation, subretinal surgery, and anti-VEGF injections, are effective but pose risks, particularly in pediatric patients, underscoring the need for a comprehensive review.
Methods: A systematic review was conducted using PubMed, Embase, and Web of Science.

Purpose: Laser photocoagulation (LPC) has been a traditional treatment for retinopathy of prematurity (ROP). However, intravitreal anti-VEGF agents such as bevacizumab and ranibizumab (IVR) have also been increasingly used. This meta-analysis aims to rigorously compare IVR to LPC in the treatment of ROP.
