  • *One eye had two CNVMs at two separate locations.

  • †Four cases (four eyes) did not undergo FFA. Three eyes were classified based on OCT and fundus examination. One case did not have FFA or OCT and was classified as subfoveal based on fundus examination.

  • ‡Among the subjects with peripapillary CNVM, five had pre-existing optic nerve pathology (optic nerve head drusen, 2; PFV, 1; Best vitelliform macular dystrophy, 1; postinflammatory, 1).

  • §Out of 35 cases and 43 eyes, the CNVMs were active in 36 eyes. These 36 eyes had 37 active CNVMs (one eye had two CNVMs). Among those with active CNVMs (36 eyes and 37 locations), FFA was available in 32 eyes (33 locations).

  • ¶Out of 43 eyes, OCT was available in 39 eyes (40 CNVMs).

  • CNVM, choroidal neovascular membrane; FFA, fundus fluorescein angiogram; OCT, optical coherence tomogram; PFV, persistent fetal vasculature.
