title: Progressive growth of bilateral choroidal osteomas in a child.
abstract: A 7-year-old girl was referred for retinal dystrophy. On examination, visual acuity was 20/20 in the right eye and 20/30 in the left eye. Fundus examination revealed bilateral orange-colored subfoveal choroidal tumors. Ultrasonography showed calcification, confirming the diagnosis of choroidal osteoma. Because vision was preserved without subretinal fluid or choroidal neovascularization, observation with calcium supplementation was recommended. Three years later, there was minimal tumor growth and visual acuity was maintained. Choroidal osteomas are rare, benign tumors that may decrease vision through decalcification, particularly when subfoveal. In these cases, cautious observation and possibly calcium supplementation may help protect vision.
