Optical coherence tomography of choroidal osteoma - 02/09/11
Abstract |
PURPOSE: To examine the cross-sectional structure of a choroidal osteoma using optical coherence tomography.
METHODS: Observational case report. A choroidal osteoma in the right eye of a 22-year-old woman was studied with fluorescein and indocyanine green fundus angiograms and optical coherence tomography.
RESULTS: The optical coherence tomography showed that a creamy-white lesion in the tumor had an increased reflectivity with a cavernous structure, whereas an orange lesion showed less reflectivity beneath the apparently intact retinal pigment epithelium. The area of less-intense whiteness in the creamy-white lesion showed higher reflectivity at the level of the retinal pigment epithelium, which precluded our viewing the deeper structure of the tumor.
CONCLUSION: Optical coherence tomography can demonstrate the cavernous structure of a choroidal osteoma at a selective stage of a tumor’s evolution, namely, when the retinal pigment epithelium is atrophied and the ossification is premature.
