Question 1: What is the characteristic appearance of retinal cavernous hemangioma?
Retinal cavernous hemangioma is characterized by the formation of grape-like clusters of thin-walled saccular angiomatous lesions in the inner retina or on the optic nerve head.
Question 2: What is the typical inheritance pattern for familial retinal cavernous hemangioma?
Although most cases are sporadic, retinal cavernous hemangioma may occur in a familial pattern with autosomal dominant inheritance.
Question 3: Which diagnostic finding is pathognomonic for retinal cavernous hemangioma on fluorescein angiography?
The sluggish blood flow in retinal cavernous hemangioma results in plasma-erythrocyte layering during angiography, which is pathognomonic for this condition.
Question 4: What is the most common clinical course for retinal cavernous hemangioma?
Retinal cavernous hemangiomas usually remain asymptomatic but may bleed into the vitreous in rare instances.
Question 5: Why is neuroimaging recommended for patients with retinal cavernous hemangioma?
Neuroimaging should always be done to rule out intracranial involvement, as intracranial hemangiomas may lead to seizures, intracranial hemorrhages, and even death.
