There were 1760 eyes in total and 856 eyes that completed 5 years follow-up. The proportion of eyes with sustained VA loss of ≥15 letters at 5 years was 22.9% (95%CI, 20.7-25.1) and VA loss of ≥30 letters was 10.8% (95%CI, 9.1-12.5). Factors independently associated with higher incidence of sustained ≥15 letter loss included age >80 years (odds ratio [OR], 1.33 for patients >80 years vs. ≤80 years; 95%CI, 1.05-1.69; P =.02), fewer injections (OR, 0.97 per injection; 95%CI, 0.96-0.98; P=.0005) and more visits at which the choroidal neovascularisation was graded as active (OR, 1.97 for eyes in upper quartile of active visits vs. eyes in lowest quartile of active visits; 95%CI, 1.39-2.79; P=.0001). Baseline VA≥70 letters was associated with reduced risk of sustained ≥30 letter loss (OR, 0.61; 95%CI, 0.38-0.98; P=.04). Baseline angiographic lesion criteria were not significantly associated with sustained VA loss.
