ABSTRACT
Ocular ischemic syndrome occurs when ocular circulation becomes impaired owing to various causes, leading to disturbances in the visual function. It ultimately progresses to neovascular glaucoma and loss of sight. Therefore, the early diagnosis and treatment of patients with ocular ischemic syndrome has a major effect on their visual prognosis. Herein, we describe a patient who complained of decreased vision in one eye. The patient was subsequently diagnosed with internal carotid artery stenosis because of neovascularity (rubeosis iridis) around the iris in the anterior eye. The vision of the patient improved immediately after carotid artery stenting. A review of the literature indicated that the visual improvement could be attributed to the reversal of retrograde blood flow, caused by internal carotid artery stenosis, to normal levels; the resolution of rubeosis in the anterior eye; and improvement in the visual field constriction.
