These changes can effect your vision. Many choroidal hemangiomas never grow or leak fluid and may be observed without treatment. Choroidal hemangiomas are not cancers and never metastasize.
Most choroidal hemangiomas are reddish to orange.
The dye is injected into the arm and travels to the blood vessels inside eye. If a tumor is in the eye, we can see specific characteristics of its circulation which can help us differentiate between it and other types of tumors. Choroidal hemangiomas are made up of relatively large and well-formed blood vessels. Each one of those blood vessels can reflect sound waves producing characteristically intense reflections from within the tumor. Most circumscribed choroidal hemangiomas can be photographed and followed for evidence of growth or leakage prior to treatment.
