Lee KE, et al. - Researchers conducted this single‐center retrospective study to describe the prognosis and various clinical features of periorbital vascular complications after facial injection of cosmetic filler or local anesthetic. The sample consisted of 10 consecutive patients who presented with occluded periorbital vessels after facial injection. Nine patients were injected with cosmetic facial fillers: seven with hyaluronic acid, one with collagen, and one with poly‐L‐lactic acid and the other patient was injected with lidocaine mixed with epinephrine. Facial injections can cause periorbital arterial occlusion, and clinical features vary depending on the location and extent of vascular occlusion and injection materials. The site of vascular occlusion and initial visual acuity were correlated with visual prognosis. In most cases, other common complications, such as skin lesions, blepharoptosis and limited extraocular movement, can be fully resolved only by supportive therapy.
