Abstract
To determine the 10-year morphological outcomes and identify potential risk factors for exudative AMD in the fellow eyes (FE) in patients with naïve exudative AMD. Data from 100 patients were retrospectively reviewed. Baseline macular neovascularization (MNV) type in the exudative AMD eye and presence of drusen, intraretinal hyperreflective foci (iHRF), non-foveal incomplete atrophy (iRORA), central retinal thickness and subfoveal choroidal thickness in the FEs were analyzed as biomarkers for progression in the second eye. 54 patients developed exudative AMD in the FE at the end of the follow-up. Subjects with type 2 and 3 MNV in the exudative AMD eye had a higher risk of exudative AMD in the FE (HR=3.365; p=0.039 and HR=3.801; p=0.037). FEs with drusen (large HR=6.938, p=0.001; cuticular HR=6.937, p<0.0001; subretinal drusenoid deposits HR=13.678, p<0.0001) and iHRF (HR=1.853, p=0.041) were also at higher risk. Seven patients were legally blind by the end of the follow-up. The rate of exudative AMD in the FE was 54% 10 years after the diagnosis in the exudative eye. The FE of patients with type 2 and 3 MNV was at high risk for early progression. Drusen and iHRF were also significant risk factors for MNV development.
