Proposed Classification System for Retinal Capillary Angiomatosis

Retinal angiomas are rare tumors that develop within the vascular bed of the retina. Their occurrence may be sporadic or as part of the multisystem disorder called von Hippel-Lindau disease. It is well established in literature that retinal angiomas have a natural history of evolving as small aneurysmal dilatations and progressing to vision-threatening retinal detachments. Several approaches to the management of these angiomas have been reported in the literature, but it is difficult to decipher which modality is best suited for which type of angioma. A classification of retinal angiomas is proposed herein. A classification system may help in developing future guidelines for the study, screening, treatment, and prognostication of patients with retinal angiomas.
