Choroidal osteoma is a benign tumor, unilateral or bilateral, acquired, and a slowly growing choroidal mass usually in the juxtapapillary region.

This tumor is usually found in healthy young women between the second and the third decade of life.

The pathological finding of choroidal osteoma is a plaque of mature bone surrounding the optic disc in the full thickness of the choroid, usually sparing the RPE.

This benign tumor may cause visual loss due to subfoveal osteoma, serous retinal detachment, and choroidal neovascularization.
