Abstract
Purpose
We present a case of choroidal osteoma and report a pattern of optical coherence tomography and multifocal electroretinography with a literature review.
Case summary
Using B-scan and CT, we performed OCT and MF-ERG in a patient diagnosed with choroidal osteoma. OCT revealed serous retinal detachment in the macula and a thick, irregular plate-like structure with high reflectivity in the choroidal mass lesion. MF-ERG demonstrated that Trace arrays show suppression of central and peripheral signals, especially in central lesions. Ring averages show reduced amplitudes in all locations, and 3D-topography of the response density shows marked suppression of the central signal and no foveal peak in comparison with the unaffected left eye.
