Unilateral Vision Loss After Hyaluronic Acid Injection: A Case Report.

Vascular occlusion causing vision loss is a rare yet one of the most devastating complications of facial esthetic fillers. In this article, we present a case of unilateral blindness and superficial skin necrosis in a 31-year-old woman after the injection of hyaluronic acid for esthetic purposes. The delicate ocular fundal findings of ophthalmic artery occlusion were demonstrated by ophthalmoscopy, optical coherence tomography, and fluorescein angiography. Magnetic resonance imaging also showed subsequent ischemic changes in the optic nerve and posterior scleral wall after ophthalmic artery occlusion. Despite management including intraocular pressure-lowering agents, globe massage, and anticoagulation with acetylsalicylic acid and hyperbaric oxygen therapy, her final vision was not restored. Given the lack of effective treatments, this report depicts the comprehensive ocular fundal findings of an ophthalmic artery occlusion after esthetic hyaluronic acid filler injection, and highlights the importance of a preventive approach to avoid such catastrophic complications.
