Retinal Artery Macroaneurysm Associated With Retinal Hemangioblastoma.

A 34-year-old Caucasian woman with a past medical history of hypertension presented with acute floaters in the right eye (OD) for 1 week. Best-corrected visual acuity (VA) was 20/20 in both eyes. Fundus examination OD (Figure 1) revealed a retinal hemangioblastoma (RH) in the temporal midperiphery with a prominent feeding artery and draining vein. A retinal arterial microaneurysm (RAM) was noted within the feeding artery, and subretinal hemorrhage with a cuff of fluid was present. Fundus autofluorescence (Figure 2) showed hypoautofluorescence in the area of the RH, RAM, and subretinal hemorrhage. A hyperautofluorescent ring surrounding the hemorrhage suggested shallow subretinal fluid. Early phase fluorescein angiography (Figure 3) demonstrated appropriate arterial and venous filling and hyperfluorescence of the RH. The RAM appeared hyperfluorescent, whereas the subretinal hemorrhage blocked. There was no evidence of leakage on late images. Optical coherence tomography (OCT) (Figure 4) through the RAM revealed an inner retinal structure with a central lumen and hyperreflective border. Mild outer retinal exudation was also noted. Fovea was normal on OCT. Fundus examination of the left eye was normal. Genetic work-up was negative for von Hippel-Lindau disease. Treatment of the hemangioblastoma was offered, but the patient preferred observation. VA remained stable, and better systemic hypertension control was recommended.
