Adjusted for baseline predictors of visual acuity, including age, study eye visual acuity, macular neovascularization area, lesion type, study eye macular atrophy, total foveal thickness, retinal pigment epithelium elevation, and predominantly persistent subretinal fluid. The baseline predictors of visual acuity change include age, study eye visual acuity, macular neovascularization area, retinal angiomatous proliferation, and retinal pigment epithelium elevation.
