CAVERNOUS HEMANGIOMA OF THE OPTIC-NERVE

Background: Cavernous hemangioma of the retina and optic disc is a rar e lesion that was first defined as a distinct entity by Gass in 1971. It is usually easily recognized by its characteristic appearance of sa ccular ''grape-like'' lesions. On fluorescein angiography, plasma-eryt hrocyte separation is seen. Methods: Two patients with cavernous heman gioma of the optic nerve were examined over a period of 5 to 10 years. Results: Although these tumors are usually considered to be static an d not capable of growth, these two cases of cavernous hemangioma of th e optic nerve showed documented growth. One case required vitrectomy f or vitreous hemorrhage.Conclusion: Cavernous hemangioma of the optic d isc can grow and can cause vitreous hemorrhage severe enough to requir e vitrectomy.
