• A case is presented in which the diagnosis was made clinically of an osseous lesion of the choroid in an otherwise normal eye. The clinical diagnosis of an osseous choristoma was confirmed by the use of ultrasonography, orbital roentgenograms, and computerized axial tomography. Enlargement of the lesion was documented photographically during a four-month period. The causes of intraocular ossification are discussed, and the typical clinical features for osseous choristoma of the choroid are suggested.
