Optical coherence tomography patterns of choroidal osteoma

PURPOSE: To determine the optical coherence tomographic images that are com monly observed in eyes with choroidal osteoma (choroidal ossification). METHODS: Three patients with choroidal osteoma were examined by optical coh erence tomography. RESULTS: We found two optical coherence tomographic patterns in the eyes wi th choroidal osteoma. First, multiple tracks of high refractivity were pres ent posterior to the tumor lesion. Second, thick and irregular plate-like, high-signal intensity areas were present in the choroid in the region of th e tumor. CONCLUSIONS: Optical coherence tomography can be useful in the diagnosis of choroidal osteoma. (C) 2000 by Elsevier Science Inc. All rights reserved.
