Abstract

PURPOSE: To report the association of pure type 2 neovascularization (NV) in age-related macular degeneration occurring almost exclusively in patients with reticular pseudodrusen. METHODS: An observational retrospective cohort study of all eyes receiving antivascular endothelial growth factor therapy for newly diagnosed neovascular age-related macular degeneration by a single practitioner over a 6-year period. Only patients with treatment-naive, pure type 2 NV who also had either pre-neovascular imaging of the study eye or imaging of a nonneovascular fellow eye available to determine baseline characteristics including drusen type and choroidal thickness were incuded. RESULTS: Of 694 patients treated for neovascular age-related macular degeneration, only 8 met the inclusion criteria with pure type 2 NV. Of these, 7 (88%) had exclusively reticular pseudodrusen (5 in the nonneovascular fellow eye, 2 in the study eye before developing NV). Six (75%) patients in the affected neovascular eye and 6 (75%) in the fellow nonneovascular eye had choroidal thickness(range, 3.0-63.3). Best-corrected vision improved from 20/89 (range, 20/30-20/796) at baseline to 20/60 (range, 20/20-20/399) at last follow-up. CONCLUSION: Pure type 2 NV is rare in age-related macular degeneration, occurring almost exclusively in patients with reticular pseudodrusen and thin choroids.
