Purpose:
The aim of this study was to report novel indocyanine green angiography findings of optic disk granulomas secondary to sarcoidosis.
Methods:
This was an observational case report.
Results:
A 36-year-old White man, 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 disks consistent with granulomas. Indocyanine green angiography revealed diffuse choroidal hypocyanescent spots with late-phase focal hypercyanescence of the optic disks in both eyes corresponding to the granulomas. After 3 months of prednisone and immunomodulatory treatment, the granulomas improved, and the optic disk hypercyanescence resolved.
Conclusion:
The authors describe a case of ocular sarcoidosis mimicking birdshot-like lesions, and indocyanine green angiography findings revealed late hypercyanescence, which resolved with treatment.
