Abstract

Purpose: To assess whether early visual acuity letter score change from baseline (ΔVALS) and early spectral domain optical coherence tomography (SD-OCT) measures of center point thickness (CPT) are associated with later ΔVALS in eyes with macular edema due to central or hemiretinal vein occlusion treated with intravitreal aflibercept or bevacizumab. Methods: Secondary analysis of a randomized clinical trial of 362 participants. Results: Considered separately at month 3, CPT (categorized as ≤ 300 μm, > 300 μm) and ΔVALS (categorized as < 5, 5–9, ≥ 10) are predictive of ΔVALS at month 6 (aflibercept: P = 0.02 for CPT and P < 0.0001 for ΔVALS; bevacizumab: P = 0.007 for CPT and P < 0.0001 for ΔVALS) and, except for CPT in the bevacizumab arm, also predictive of ΔVALS at month 12 (aflibercept: P = 0.03 for CPT and P < 0.0001 for ΔVALS; bevacizumab: P = 0.18 for CPT and P < 0.0001 for ΔVALS). Month 3 predictors are also associated with average ΔVALS from months 4 to 12 (CPT P = 0.01 in the aflibercept arm, P = 0.02 in the bevacizumab arm; ΔVALS > 10 versus < 5; P < 0.001 for both aflibercept and bevacizumab). When month 3 measures are considered jointly, ΔVALS effect remains significant for average ΔVALS from months 4 to 12 (aflibercept: P = 0.002; bevacizumab: P < 0.0001) but not CPT (aflibercept: P = 0.18; bevacizumab: P = 0.22). Conclusion: While both month 3 ΔVALS and CPT are predictive of ΔVALS after month 3 through month 12, early ΔVALS has a stronger relationship than CPT with later ΔVALS. SCORE2 registration number is NCT01969708. [Figure not available: see fulltext.]
