Correlation between change in central subfield thickness and change in visual acuity in macular edema due to retinal vein occlusion: post hoc analysis of COPERNICUS, GALILEO, and VIBRANT.

ABSTRACT:

Purpose

Assess correlation between change in central subfield thickness (CST) and change in best-corrected visual acuity (BCVA) in eyes with macular edema due to retinal vein occlusion (RVO) that received intravitreal aflibercept injections (IAI).

Methods

Post hoc analysis of COPERNICUS and GALILEO trials for CRVO and VIBRANT trial for BRVO with relationships determined using Pearson correlation coefficient.

Results

In COPERNICUS, correlations (r) between change in CST and change in BCVA from baseline at weeks 12, 24, 52, and 100 were -0.36 (95% CI: -0.52, -0.18; P < 0.001), -0.38 (95% CI: -0.53, -0.20; P < 0.001), -0.44 (95% CI: -0.58, -0.27; P < 0.001), and -0.41 (95% CI: -0.56, -0.23; P < 0.001), respectively. CST changes accounted for only 21% of the variance in B
