Ischemic Syndrome

AbstractOcular ischemic syndrome (OIS) is a vision-threatening condition due to inadequate arterial supply to the orbital contents. OIS is commonly described secondary to severe carotid artery stenosis and most often observed by ophthalmologists. However, OIS may rarely also result in an interventional radiology setup during balloon test occlusion (BTO) of the internal carotid artery. BTO is a procedure to assess for the adequacy of the circle of Willis to compensate for a permanent parent arterial sacrifice by temporarily occluding the flow in the internal carotid artery using a balloon. Here, we present a case of OIS in a patient who underwent BOT as a part of presurgical evaluation for the excision of carotid body tumor.

Ischemic Syndrome

Purpose: This article describes a case of ocular ischemic syndrome (OIS) in a patient with a congenitally absent left internal carotid artery (ICA). Methods: Retrospective case report with anterior-segment and fundus photography, fluorescein angiography (FA), and computerized tomography angiography (CT-A). Results: A 31-year-old-man was found to have neovascularization of the iris (NVI) and angle of the left eye. FA showed capillary nonperfusion in the temporal periphery. He required intravitreal bevacizumab and triamcinolone injections and 2 panretinal photocoagulation treatments for persistent rubeosis and cystoid macular edema. Transient right-eye vision loss prompted CT-A, revealing an absent left ICA. Three years following presentation, FA continued to show delayed arteriovenous flow suggestive of OIS. He has required intravitreal bevacizumab injections every 12 weeks for persistent NVI. Conclusion: Congenitally absent left ICA with resultant cerebrovascular insufficiency is a rare cause of OIS, underscoring the pathophysiological principles of insufficient blood supply to the ophthalmic artery.

Ischemic Syndrome

Background: Treatment of cervical internal carotid artery (ICA) stenosis has contributed to the improvement of ocular ischemic syndrome. However, there have been few cases of visual impairment caused by ocular ischemic syndrome due to intracranial ICA stenosis, which improved through intracranial stent placement. Case Description: A 76-year-old man presented with right-sided paralysis. Radiographic examination revealed severe stenosis of the left intracranial ICA (distal cavernous-infraclinoid portion) and a watershed infarction of the left cerebral hemisphere. Conservative therapy including antiplatelet drugs was initiated, but severe visual acuity disturbance in his left eye occurred 1 month after onset. The antegrade ocular artery flow recovered after urgent intracranial stent placement, and his vision improved immediately after the procedure. Conclusion: Visual impairment presenting as ocular ischemic syndrome can occur due to severe stenosis of the intracranial ICA, and treatment of these lesions could improve the symptoms.
