Retinal Astrocytoma is a rare and benign tumor of the retina most frequently seen in patients
with tuberous sclerosis or, less frequently, neurofibromatosis. Astrocytoma of the retina are probably best regarded as benign pilocytic astrocytomas, comparable
to the tumors seen in the optic nerve. Longstanding cases may be severly calcified and may radiologically resemble a retinoblastoma.
