Smooth borders between inner nuclear layer and outer plexiform layer predict fewer macular edema recurrences in branch retinal vein occlusion
Abstract We hypothesized the smoothness of the border between the inner nuclear layer (INL) and outer plexiform layer (OPL) associates with the frequency of macular edema (ME) recurrences secondary to branch retinal vein occlusion (BRVO). Thirty-seven consecutive eyes with BRVO treated with anti-vas...

| Summary: | Abstract We hypothesized the smoothness of the border between the inner nuclear layer (INL) and outer plexiform layer (OPL) associates with the frequency of macular edema (ME) recurrences secondary to branch retinal vein occlusion (BRVO). Thirty-seven consecutive eyes with BRVO treated with anti-vascular endothelial growth factor (VEGF) injections at 1-year follow-up were included. We manually traced the border between the INL and OPL within the 1.5-mm vertical line from the fovea on optical coherence tomography (OCT) images at the initial visit. The jagged ratio (JR), the border length divided by the spline curve length, was calculated. We performed univariate and multivariate regression analyses, including JR, patient characteristics, number of cystoid spaces in the INL, INL area, and outer retina area. Multivariate regression analysis showed JR significantly correlates with the total number of anti-VEGF injections (P < 0.0001). Moreover, the mean JR was significantly lower in the nine eyes receiving two or fewer injections than in the 28 eyes receiving three or more injections (1.02 ± 0.01 vs. 1.13 ± 0.06, P < 0.0001). A smooth border between the INL and the OPL on OCT images at the initial visit may be a biomarker for fewer ME recurrences in eyes with BRVO. |
