Abstract

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 BCVA changes; every 100-µm decrease in CST was associated with a 2.1-letter increase in BCVA (P = 0.003). Similar findings were noted for GALILEO (r, −0.45 to −0.23) and VIBRANT (r, −0.36 to −0.32) trials.

Conclusion

In eyes treated with IAI for macular edema due to RVO, correlation between change in CST and change in BCVA was weak to moderate. While change in CST may be helpful in determining the need for anti-VEGF therapy, these findings do not support using changes in CST as a surrogate for changes in visual acuity outcomes.
