Intravitreal anti-vascular endothelial growth factor for the treatment of chronic central serous retinopathy: a meta-analysis of the literature

Abstract

ObjectiveThe purpose of this study was to evaluate the role of anti-vascular endothelial growth factor (anti-VEGF) treatment on the functional and structural parameters of chronic central serous retinopathy (CSR).MethodsPubMed was used to systematically review literature published from 1 January 2009 to 1 July 2022. Studies were included if patients in their cohort had symptoms for more than 3 months, anti-VEGF treatment was provided and the following outcomes were reported: best-corrected visual acuity (BCVA), central macular thickness (CMT) and proportion of subretinal fluid (SRF) resolution.Results339 eyes met inclusion criteria with a mean patient age of 45.8±4.9 years. The weighted mean baseline BCVA for the 20 studies was 0.39±0.23 logMAR, which improved to 0.28±0.24 after treatment with anti-VEGF injections (p=0.069). The weighted baseline CMT for the 20 studies decreased from 395.2±52.0 µm to 243.0±41.9 µm (p<0.001). The weighted overall percentage of SRF resolution was 68.4%.ConclusionAnti-VEGF treatment demonstrated significantly decreased macular thickness and resolution of SRF in the treatment of chronic CSR without any reported adverse effects. However, BCVA did not significantly improve with pharmacotherapy.
