Fundus examination of the left eye revealed a persistent hyal oid artery emerging from the optic disc, surrounded by primary vitreous on its anterior end, inserting on the nasal pre equatorial retina. Macular ect opia and sectorial chorioretinal atrophy were also present. Fluorescein ang iography disclosed a permeable and tight,hyaloid artery. There were no macu lar or optic nerve anomalies precluding Visual acuity. After phakoemulsific ation, the patient regained a visual acuity of 0.9 on the left eye.
