a Widefield Optos imaging of the right eye of a patient with von Hippel-Lindau disease demonstrates a retinal hemangioblastoma in the superotemporal quadrant with associated dilated feeding and draining vessels. b Widefield fluorescein angiography of the right eye reveals fluorescein uptake and leakage from the hemangioblastoma with peripheral retinal nonperfusion in the superotemporal quadrant anterior to the tumor
