Choroidal neovascularization and geographic atrophy are potential complications of early onset large colloid drusen

The authors report a case of large colloid drusen (LCD) complicated by choroidal neovascularization (CNV) and geographic atrophy (GA). A 54-year-old man was referred to the authors' department with diagnosis of early onset retinal drusen. Multimodal imaging led to a diagnosis of LCD complicated by GA in the right eye and CNV in the left eye. The patient received a single injection of intravitreal aflibercept (Eylea; Regeneron, Tarrytown, NY) in the left eye. Six months later, best-corrected visual acuity improved to 20/25, and spectral-domain optical coherence tomography still showed absence of subretinal and intraretinal fluid. GA and CNV are possible complications of LCD, and contrary to previous beliefs, it should therefore not be considered as a benign condition. Intravitreal aflibercept could be considered as a useful treatment in cases complicated by CNV.
