4 Ophthalmic Pathology and Intraocular Tumors
Part II: Intraocular Tumors: Clinical Aspects
Chapter 18: Vascular Tumors
Vascular tumors (also called angiomatous tumors) are benign lesions that can affect the retina and/or choroid. Some of these vascular lesions are not true neoplasms but rather are hamartomatous lesions or vascular malformations. Some are associated with systemic disorders. Although these vascular lesions do not have malignant potential, they can cause serious ocular morbidity, leading to permanent vision loss. Tumors in this category include choroidal hemangiomas (with circumscribed and diffuse variants) and retinal vascular tumors, such as retinal cavernous hemangioma, retinal arteriovenous malformations, retinal capillary hemangioblastoma, and retinal vasoproliferative tumor.
