Aim: To evaluate the prevalence, clinico-demographic features & morphometric analysis of RAP.
Method:Retrospective clinical chart review study of 112 eyes with neovascular age related macular degeneration who underwent multimodal imaging (SD-OCT, EDI-OCT, IR, ICGA & DFA) between 2015 to 2017.
Results:14 eyes had features of RAP (prevalence:12.5%) with mean age of 72.1 years (+11.6) & equal sex ratio. Reticular pseudodrusen (78.5%), intraretinal fluid(IRF;78.5%) & hyperreflective PED(45.5%) were most consistent features on SD-OCT. Focal hot spot with late leakage on ICGA was illustrated in all eyes (100%), with presence of feeder vessel documented in 10 of 14 eyes(71%).Simultaneous eye-tracked SD-OCT with ICGA demonstrated RPE erosion corresponding to the point of leak in all eyes(100%).
Conclusion: RAP represents an important variant of neovascular AMD(12.5% of Cases) with distinctive features including reticular pseudodrusen, IRF, RPE erosion & focal hotspot with late leakage on ICGA
