Choroidal osteoma with CNVM – Successful treatment with intravitreal Bevacizumab

Twenty-seven years old healthy woman presented with complaints of sudden painless blurred vision in right eye for 1 week. On examination, visual acuity was 20/30 in the right eye and 20/20 in left eye. Fundus examination OS was normal; OD demonstrated a flat, opaque, yellowish parapapillary choroidal lesion with grayish membrane associated with minimal subretinal fluid suggestive of a CNVM in the center. B-scan ultrasonography revealed findings consistent with a choroidal osteoma. Fundus fluorescein angiography of the right eye revealed a relatively well-defined area of hyperfluorescence that increased in size and intensity in the later phases suggestive of active extrafoveal CNVM. Optical coherence tomography confirmed the extrafoveal CNVM with subfoveal fluid. She was treated with intravitreal Bevacizumab OD. At the 2 weeks visit, vision OD improved to 20/20. The FFA and OCT revealed a resolved CNVM. Intravitreal Bevacizumab may be an effective alternative in the management of CNVM secondary to choroidal osteoma.
