Serpiginous Choroiditis: 34-year old Afghani woman with history of bilateral choroiditis. A: Red free fundus photography of the right eye reveals geographic areas of choroidal atrophy, pigment clumping, and cystoid macular edema. B: In FA, border staining delineates atrophic areas with some blockage from pigment proliferation. Early accumulation of dye in cystoid spaces is evident. C, D: Mid-phase and late phase indocyanine green angiography reveals choriocapillaris loss in areas of healed lesions with preservation of large choroidal vessels. Choroidal circulation in non-involved areas is normal. Nazari Khanamiri H, Rao NA. Serpiginous choroiditis and infectious multifocal serpiginoid choroiditis.
