OPH-1. Evaluation of choroidal osteoma by optical coherence tomography.The purpose of this study was to describe the optical coherence tomography Optical coherence tomography (OCT) is an interferometric, non-invasive optical tomographic imaging technique offering millimeter penetration (approximately 2-3 mm in tissue) with micrometer-scale axial and lateral resolution. (OCT) findings in a case of choroidal cho·roi·dal adj. Of or relating to the choroid. choroidal pertaining to or emanating from the choroid. choroidal hypoplasia osteoma osteoma /os·te·o·ma/ (os?te-o´mah) a benign, slow-growing tumor composed of well-differentiated, densely sclerotic, compact bone, occurring particularly in the skull and facial bones. . A patient with suspected unilateral choroidal osteoma first underwent ultrasonography and fluorescein angiography to verify the diagnosis. The patient then underwent evaluation of the osteoma by OCT. The OCT scan revealed marked retinal atrophy with cystic changes, overlying overlying suffocation of piglets by the sow. The piglets may be weak from illness or malnutrition, the sow may be clumsy or ill, the pen may be inadequate in size or poorly designed so that piglets cannot escape. atrophy of the retinal pigment epithelium, and increased reflectivity of the choroid. Our findings were compared to the two previous reports of choroidal osteoma evaluation by OCT, and the findings were similar. OCT appears useful in evaluating choroidal osteomas. Avit J.
