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.
Conclusion : In patients with choroidal osteoma, OCT can reveal thick plate-like high reflectivity with an
irregular outer surface, and MF-ERG can predict retinal dysfunction.
