Clinical Observations and the Anatomical Basis of Blindness After Facial Hyaluronic Acid Injection

ConclusionsThe severity of blindness caused by HA injection may be associated with the occlusion site. Our clinical observations indicate that conventional treatments, such as retrobulbar hyaluronidase injection, are insufficient to relieve visual impairment. Injecting as little as 0.08  ml of HA into the facial branch is enough to cause central retinal artery embolism. Limiting the volume per injection could represent a simple prophylactic strategy.Level of Evidence VThis journal requires that authors assign a level of evidence to each article.
