BACKGROUND AND OBJECTIVE: To study the relationship between baseline morphologic characteristics of the choroidal neovascular (CNV) lesion and long-term development of macular atrophy in eyes with neovascular age-related macular degeneration (AMD) treated with ranibizumab (Lucentis; Genentech, South San Francisco, CA) PATIENTS AND METHODS: Certified graders evaluated baseline and 7-year follow-up (SEVEN-UP study) images of 41 eyes from the MARINA/ANCHOR and HORIZON trials. Using GRADOR software and stepwise linear regression, graders correlated lesion characteristics on fluorescein angiography (FA) at both visits with areas of definite decreased autofluorescence (DDAF) on fundus autofluorescence (FAF) imaging at the SEVEN-UP visit RESULTS: Three of 41 eyes (7.3%) had macular atrophy on FA at baseline (mean ± standard deviation [SD] size: 0.29 mm(2) ± 1.50 mm(2)), 29 (70.7%) at SEVEN-UP (mean ± standard deviation [SD] area: 7.42 mm(2) ± 7.97 mm(2)). On FAF imaging at the SEVEN-UP visit, all 41 eyes (100%) had DDAF (mean ± SD size: 10.29 mm(2) ± 8.07 mm(2)). Variables significantly associated with area of DDAF at the SEVEN-UP visit were the area of leaking CNV lesion components (coefficient: 0.953; P < .001), the area of other lesion components (coefficient: 1.094; P = .038), and the area of retinal pigment epithelial (RPE) atrophy (coefficient: 1.334; P = .040) on baseline FA imaging CONCLUSION: The area of DDAF at more than 7 years after initiation of ranibizumab therapy was 35% larger than the original CNV lesion. The baseline area of leaking CNV and other components of the CNV lesion and the baseline area of RPE atrophy were important predictors of the area of definite decreased autofluorescence, presumably corresponding to areas of photoreceptor and RPE loss. The findings from this study may guide hypothesis generation for future AMD trials |
