Serpiginous choroidal atrophy
Serpiginous choroidal atrophy, also known as geographic helicoids peripapilltary choroidopathy, is a chronic recurrent disease of the choroidal capillaries and retinal pigment epithelium (RPE) at the posterior pole of the fundus. The disease was first reported by Junis as juxtapapillary choroidoretinitis, and later some authors called it geographic choroiditis, serpiginous choroiditis or serpiginous choroidopathy. In 1962, Franceschetti called it geographic helicoid peripapillary retinochoroidal degeneration. The clinical manifestations described by different authors are all chronic and progressive choroidal capillaries and RPE lesions.
