Retinal Capillary Hemangioma
Clinical Features:
These lesions can affect both the retina and optic nerve. They start out small and can gradually enlarge with the possibility of intraretinal and subretinal exudation that can involve the macula and affect visual acuity. They have characteristic tortuous and dilated feeding and draining arteries and veins (Fig. 22.1.1 and Fig. 22.1.2), respectively. Multiple and bilateral lesions are common in the setting of Von Hippel–Lindau disease.
