Abstract

<b><i>Purpose:</i></b> The current body of evidence on the efficacy and safety of anti-VEGFs for macular oedema secondary to branch retinal vein occlusion (BRVO) is steadily growing as large clinical trials and observational studies are continually completed. The aim of this meta-analysis is to analyse anatomical and functional outcomes in response to anti-VEGF therapy using evidence generated from a pooled analysis of current clinical trials and observational studies. <b><i>Methods:</i></b> The current meta-analysis includes treatment of BRVO with aflibercept, bevacizumab and ranibizumab from randomised controlled trials and observational studies. Inclusion criteria included peer-reviewed publications with at least a 12-month follow-up period. On literature review using multiple electronic databases (PubMed, Embase and Cochrane), 22 studies met the inclusion criteria. Baseline patient characteristics, study design, sample size and 12- and 24-month change in best corrected visual acuity (BCVA) and central foveal thickness (CFT) as measured on optical coherence tomography imaging were pooled in a meta-analysis. Data were then stratified by study design and anti-VEGF therapy in subgroup analyses. <b><i>Results:</i></b> A total of 1,236 eyes from 22 studies were included in this meta-analysis. Mean baseline BCVA ranged from 66 ETDRS letters (20/50 Snellen equivalent) to 35 letters (20/200 Snellen). Mean baseline CFT ranged from 406.0 to 681.0 µm. Anti-VEGF treatment demonstrated an overall mean improvement in BCVA at 12 months of 14 letters (95% CI 12.0 to 16.2, <i>p</i> &#x3c; 0.001) and CFT reduction of 228 µm (95% CI –278.9 to –176.1, <i>p</i> &#x3c; 0.001). The BCVA gains at 12 months were maintained to month 24 with a mean gain of 12.5 letters (95% CI 6.3 to 18.8, <i>p</i> &#x3c; 0.001), as well as reduction of CFT of 238 µm (95% CI –336.0 to –140.2, <i>p</i> &#x3c; 0.001). No cases of endophthalmitis or glaucoma were reported in any study. <b><i>Conclusion:</i></b> This meta-analysis confirms the comparable safety and efficacy of anti-VEGF therapies for patients with cystoid macular oedema secondary to BRVO. There is a need for randomised prospective comparative trials of anti-VEGF agents for BRVO.
