GA and CNV/MNV share the genetic risk factors of HTRA1, complement factor H, complement factors 3 and 2, and ARMS2, and clinical risk factors of large drusen, cuticular drusen, intraretinal hyperreflective foci, and subretinal drusenoid deposits, suggesting that simultaneous GA and CNV/MNV represents a continuum of AMD. This evidence concerns the gene HTRA1 and age-related macular degeneration.
