The clinical spectrum of periorbital vascular complications after facial injection.

Facial injections can cause periorbital arterial occlusion, and the clinical features are diverse according to the site and extent of vascular occlusion and injection materials. Visual prognosis was associated with the site of vascular occlusion and initial visual acuity. Other common complications, such as skin lesions, blepharoptosis, and limited extraocular movement, can fully resolve only with supportive treatments in most cases.
