Iris Vascular Malformation with 360-Degree Iridocorneal Angle Affectation

Abstract

Vascular iris lesions are rare and can sometimes be associated to systemic vascular lesions. They usually cause spontaneous recurrent hyphema. The differential diagnosis should be considered primarily with iris rubeosis and with highly vascular tumors as iris melanoma. Generally, vascular lesions of hemangioma type are located in the iris without extension to iridocorneal angle. We present a case of a 77-year-old male with an iris vascular lesion suggestive of racemose hemangioma, who is asymptomatic, and with 360-degree iridocorneal angle affectation showing no lesions at any other location.

Multimodal Imaging in Iris Vascular Tumors: A Case Series

“…AS-OCT in IAVM shows the vessel as a poorly defined hyporeflective structure in the iris stroma [ 8 , 9 ].…”

“…Furthermore, treatment with antiangiogenic drugs has been described, but its superiority to observation is not clear [ 2 ]. Finally, sectoral iridectomy could be considered when repeated laser treatment fails or in cases where a histopathological diagnosis is crucial to rule out a malignant lesion [ 8 ].…”
