Nine cases of cavernous hemangioma of the retina.

The findings in nine patients with cavernous hemangioma of the retina confirmed the accepted characteristics of this malformation. Clusters of dark-red saccular aneurysms within the inner retinal layers were partly covered by a white epiretinal membrane. There was no clinical or angiographic evidence of exudation from the angioma and there was no growth during a median follow-up period of 6.3 years. The size of the aneurysms, the extent of the lesion, and the associated venous malformations varied greatly from case to case. Fluorescein angiographic findings during follow-up periods of as much as 16 years suggested progressive thrombosis and organization of the angioma.
