Peripapillary Atrophy — Characterized by a diffuse circumferential, choroidal atrophy — May extend up to half a disc diameter beyond the disc margin — Rarely focal peripapillary atrophy — Has accompanying RPE hyperplasia — Up to 5-10% of POHS patients develop CNVM ↳ anytime you has defect in RPE you have choroidal neovascular rub torea is temporal to ONH ⑳ Hepa Nasal PPA ↳ 8 Echorrido rb Vascular here , world take temporal lot a to sal & face reach na need Don't have to in allchanges eyes both bitoffen medo B.
