Choroidal osteomaの2症例

Two cases of choroidal osteoma

　26歳女性および30歳女性の片眼に生じたcho-roidal osteomaの2症例の検眼鏡的所見の経過につき述べた。本疾患の診断には，特有な眼底所見に加え，X線，超音波検査，CT scanによる検査所見が重要であることを述べ，かつ鑑別上の問題点についても述べた。

We followed up two females, aged 26 and 30 years, who manifested a yellowish-white disciform choroidal lesion unilaterally. The lesions showed a slight tendency for increase in size during the follow-up period of over 3 years. While the lesions were thought to be choroidal hemangiomas ini-tially, subsequent examinations including x-rays, ultrasonography and CT scan indicated the lesions to be composed of electronically high density tissue.

Ophthalmoscopic, angiographic and radiological features were in accordance with those of choroidal osteoma.
