Abstract
Facial filler injection for soft-tissue augmentation, wrinkle reduction, and rejuvenation has recently become increasingly popular. This procedure is well accepted and widely performed because of its safety and excellent outcomes. However, complications may occur even in the most skilled hands. A 36-year-old female presented with immediate loss of vision in her right eye following the periocular injection of cosmetic hyaluronic acid facial filler into the glabellar region. The visual loss was accompanied by weakness of her left arm. Blindness may complicate cosmetic facial filler injection. The treating physician should have a firm knowledge of the facial vascular anatomy, and the patient should be aware of the potential blinding complications associated with facial filler injection.
