—Spontaneous involution, a rarely observed occurrence in a choroidal osteoma, was noted in the eye of a 25-year-old woman who had been followed up for 8 years.
Report of a Case.
—In 1978 a 17-year-old white woman noted blurred vision in her right eye. A yellow-red choroidal lesion measuring 3×4 disc diameters was found in the right posterior pole. It involved the superior half of the macula, reducing visual acuity to 20/30 (Fig 1, top). Ultrasonographic (Fig 1, bottom) and computed tomographic findings supported the clinical diagnosis of a choroidal osteoma.In 1979, while the patient participated in a basketball game, her visual acuity suddenly decreased to 20/60 due to the development of a serous retinal detachment associated with a hemorrhage under the retinal pigment epithelium overlying the center of the lesion (Fig 2, top). The hemorrhage and detachment slowly resolved, leaving rather mottled-appearing retinal pigment epithelium
