Indocyanine Green Angiography of Optic Disc Granuloma in Ocular Sarcoidosis.

Abstract

To report novel indocyanine green angiography (ICG) findings of optic disc granulomas secondary to sarcoidosis. Observational case report. A 36-year-old white male, who had previously been evaluated for birdshot chorioretinopathy and tested HLA-A29 negative, was referred for evaluation of choroidal lesions in both eyes. Fundus examination revealed ovoid choroidal lesions bilaterally in the posterior pole. Optical coherence tomography demonstrated bilateral focal choroidal elevations in the posterior pole and optic discs consistent with granulomas. ICG revealed diffuse choroidal hypocyanescent spots with late-phase focal hypercyanescence of the optic discs in both eyes corresponding to the granulomas. After three months of prednisone and immunomodulatory treatment, the granulomas improved and the optic disc hypercyanescence resolved. We describe a case of ocular sarcoidosis mimicking birdshot-like lesions, and ICG findings revealed late hypercyanescence, which resolved with treatment.
