Choroidal hemangioma

Choroidal hemangioma is an uncommon benign vascular tumor of the choroid that can be circumscribed or diffuse. Circumscribed choroidal hemangiomas are usually diagnosed between the second to fourth decade of life when they cause visual disturbances owing to the development of an exudative retinal detachment. Circumscribed tumors occur sporadically, without any associated local or systemic anomalies. Diffuse choroidal hemangiomas are usually evident at birth and generally occur as a part of neuro-oculo-cutaneous hemangiomatosis (Sturge-Weber syndrome).
