Choroidal osteoma, a benign tumor and involving one eye frequently, occurred around optic disc in usually healthy young women, In our cases, the ophthalmoscopic examination revealed a sharply circumscribed, slightly elevated, orange-red subretinal lesion with irregular geographic borders and the tumors became depigmented and yellow-white with time. Diffuse and mottled depigmentation of the overlying pigment epithelium was occurred and the tufts of branching blood vessels were scattered on the tumor suface. In case 1, the tumor size was enlarged with pregnancy. In case 2, the tumor size was progressively enlarged with time in right eye and new lesion was developed in left eye, which had been normal at the first visit. The causes of visual disturbance were degeneration of retinal pigment epithelium and sensory retina in case 1 and right eye of case 2, and submacular neovascular membrane in left eye of case 2.
