[Multifocal choroiditis associated with serpiginous choroiditis and choroidal neovascularization: a case report]

We treated a patient with multifocal choroiditis (MFC) associated with serpiginous choroiditis and choroidal neovascularization (CNV).In a 27-year-old woman whose left eye showed serpiginous choroiditis near the optic disc and multiple irregular chorioretinal scars and exudates in peripheral and near-peripheral zones, fluorescein angiography demonstrated diffusely scattered hyperfluorescent dots and late leakage from retinal vessels. The lesion near the optic disc showed hypofluorescence in the early venous phase, and hyperfluorescence in the late phase. Sub-Tenon injection of triamcinolone acetonide did not effectively treat the CNV secondary to serpiginous choroiditis, but direct laser photocoagulation was successful, achieving improved visual acuity.We suggest that this patient's MFC and serpiginous choroiditis represented a single process rather than independent events. With lesions at the posterior pole, CNV developed secondarily. In this case, direct laser photocoagulation proved useful.
