Although vascular tumors do not have malignant potential, they can cause serious ocular morbidity that leads to permanent vision loss.
Vascular tumors can be grouped by their primary location in the choroid or the retina and by whether they are prenatal or postnatal in origin.
Prenatal (eg, congenital) retinal vascular tumors have tight junctions and do not have associated leakage or exudation.
Vascular tumors can be associated with systemic disorders such as Sturge-Weber, Wyburn-Mason, and von Hippel–Lindau syndromes.
