New Study Confirms Pathophysiology of Filler-Induced Blindness

supratrochlear artery

A team of researchers used a fresh cadaver perfusion technique to substantiate whether arterial embolism is responsible for hyaluronic acid-induced blindness. Working with a fresh cadaver head perfusion model that simulates both physiologic blood pressure and flow rate of the carotid artery, ophthalmic artery and supratrochlear artery, Ki-Hyun Cho, MD, MSc, et al, cannulated the carotid artery and exposed the internal jugular vein for open venous drainage.
