title: Review of choroidal osteomas.
abstract: Choroidal osteomas are rare benign ossifying tumors that appear as irregular slightly elevated, yellow-white, juxtapapillary, choroidal mass with well-defined geographic borders, depigmentation of the overlying pigment epithelium; and with multiple small vascular networks on the tumor surface. Visual loss results from three mechanisms: Atrophy of the retinal pigment epithelium overlying a decalcified osteoma; serous retinal detachment over the osteoma from decompensated retinal pigment epithelium, and most commonly from choroidal neovascularization. Recent evidence points to the beneficial effects of intravitreal vascular endothelial growth factor antagonists in improving visual acuity in serous retinal detachment with or without choroidal neovascularization.
