Choroidal osteomas are benign neoplasms in which areas of the choroid are replaced with mature bone. The tumors are most commonly solitary, unilateral, and juxtapapillary in location which helps differentiate them from idiopathic sclerochoroidal calcification. They appear clinically as ovoid subretinal lesions, ranging from yellow-white to orange-red in color, sometimes with overlying pigmentary changes.
