BackgroundEnhanced-depth imaging optical coherence tomography (EDI-OCT) provides high-resolution imaging of the choroid. Herein, we report multimodal imaging, including EDI-OCT, of a case of sarcoid choroidal granulomas.FindingsA 63-year-old female with biopsy-supported sarcoidosis presented with unilateral multifocal choroidal granulomas. Enhanced-depth imaging optical coherence tomography (EDI-OCT) demonstrated a homogenous hyporeflective choroidal lesion with choriocapillaris thinning and sparing of the surrounding choroid. The patient was started on oral steroids with a weekly taper schedule. Within 5 weeks, the choroidal lesions had clinically resolved with return of normal-appearing choroidal architecture on EDI-OCT. Indocyanine green angiography, however, demonstrated hypofluoresence at the sites of choroidal granulomas 11 months after the clinical resolution, suggesting a longstanding choroidal perfusion deficit undetected by OCT.ConclusionsChoroidal imaging via EDI-OCT provides detailed morphologic information of sarcoid granulomas and can accurately demonstrate structural resolution of the lesions.

Multimodal imaging including spectral domain optical coherence tomography analysis in eyes of patients with systemic amyloidosis shows deposition in the choroid. The deposition may cause a secondary toxic and or barrier effect resulting in diffuse retinal pigment epithelium and photoreceptor dysfunction.
