Choroidal Osteoma: with regard to a case.

Abstract

Introduction: choroidal osteoma (OC) is a rare benign tumor of the choroid, capable of producing real bone tissue. It typically affects young healthy women, and it is located in the posterior pole, preferably in the juxtapapillary region. It is usually a unilateral lesion with still unknown etiology. Diagnosis can be made by ultrasonography and computed tomography by showing the corresponding calcifed plaque of the injury. Case study: we report a case of choroidal osteoma in a female patient of 36 years of age with loss of visual acuity of the left eye and a history of ocular trauma. In the TAC there was an elongated orbit calcifcation of about 7mm, located in the upper posterior region of the left eye, appears juxtapapillary, which is not modifed by the contrast in relation to choroidal osteoma. Optical coherence tomography was performed in the LE, where EPR evidenced elevation, a possible lesion suggestive of choroidal neovascular membrane and subretinal fuid, applying 3 doses of antiangiogenic, improving vision. Conclusions: choroidal osteoma is a rare benign intraocular tumor, more common in young healthy patients whose diagnosis was confrmed by CT visible calcifcation; among its complications that cause low vision is the exudative detachment and bleeding; being photodynamic therapy, photocoagulation and antiangiogenic treatment of choice.
