Purpose:
To report, in vivo, on the quasi-histologic characteristics of a sarcoid choroidal granuloma as visualized by Enhanced Depth Imaging Spectral Domain Optical Coherence Tomography (EDI SD-OCT).
Methods:
A 49 year-old woman showing a choroidal granuloma secondary to sarcoidosis was imaged by EDI OCT.
Result:
On EDI SD-OCT examination, sarcoid choroidal granuloma appears as a localized hyporeflectivechoroidalthickening. Two weeks after systemic corticosteroids, the thickness of the granuloma decreased from 568 μm to 356 μm. Five months later, it reached 274 μm, and after eleven months, it decreased to 150 μm.
Conclusion:
EDI SD-OCT allows direct visualization of choroidal granuloma secondary to sarcoidosis and evaluation of lesion regression after treatment.
