Purpose: To assess the impact of ethnicity, age, and ocular characteristics on ranibizumab efficacy in myopic choroidal neovascularization (CNV). Methods: In this post hoc subgroup analysis from the phase III RADIANCE study, best-corrected visual acuity (BCVA) outcomes and treatment exposure were analyzed in 105 patients treated with ranibizumab 0.5 mg. Baseline categories included ethnicity, age, baseline BCVA, lesion area, CNV lesion area, refraction sphere, axial length, subretinal fluid, and location of CNV. Results: At month 12, the mean change in BCVA was numerically higher in East-Asians than in Caucasians (17.0 vs. 14.1 letters). The median number of injections varied with ethnicity (East-Asians vs. Caucasians: 2 vs. 3), baseline BCVA (highest vs. lowest: 1 vs. 4), CNV lesion area and lesion area (largest vs. smallest: 5 vs. 1 and 5 vs. 2). Conclusions: East-Asians showed numerically higher BCVA gains than Caucasians. The number of injections varied across subgroups, emphasizing the need for individualized treatment.
