A hemangioma is a tumor comprised of blood vessels and can grow within the choroid, the blood vessel layer beneath the retina. Choroidal hemangiomas are not cancers and never metastasize. However, if the hemangioma is located in the area of central vision of the eye it can leak fluid that causes a retinal detachment and visual function may be affected.
Many choroidal hemangiomas can be safely monitored by your eye doctor without the need of further treatment. Photographs can be used to document evidence of growth or leakage and the need for treatment. Treatment options may include laser photocoagulation to decrease the amount of fluid leakage or low doses of external beam radiation therapy.
