Purpose:To evaluate the influence of arteriovenous (AV) sheathotomy on retinal function with central multifocal electroretinography (mfERG) in eyes with macular edema secondary to branch retinal vein occlusion (BRVO).Methods:Fifteen patients (15 eyes) who underwent AV sheathotomy for macular edema secondary to BRVO were included in the study. Best-corrected visual acuity and mfERG responses from the most central seven hexagons were analyzed before and 6 months after the operation.Results:The mean preoperative Early Treatment Diabetic Retinopathy Study (ETDRS) score±SD was 34.1±12.7 letters (Snellen equivalent, 20/50) and significantly improved up to 40.5±10.9 letters (Snellen equivalent, 20/40) at 6 months after AV sheathotomy (P= 0.027, Wilcoxon signed rank test). The mean preoperative P1 amplitude±SD of the most central 7 hexagons was 39.30±10.86 nV/deg 2 for the affected eye versus 47.72±6.67 nV/deg 2 for the normal fellow (control) eye (P= 0.013, Mann–Whitney U test) and significantly increased up to 50.71±15.58 nV/deg 2 at 6 months after the operation (P= 0.014, Wilcoxon signed rank test). Significant correlations between preoperative and postoperative ETDRS score and preoperative P1 amplitude were present (r= 0.929, P< 0.001; r= 0.768, P= 0.001; respectively [Spearman correlation]).Conclusions:AV sheathotomy improved macular function and anatomical outcome as measured by ETDRS score and mfERG responses in patients with macular edema due to BRVO.
