Anatomical Guideline for Retrobulbar Hyaluronidase Injection

Vision loss following cosmetic filler injections is a rare but devastating complication resulting from inadvertent intravascular embolization, most often affecting the ophthalmic artery. Retrobulbar hyaluronidase injection has been proposed as an emergency intervention, yet anatomical guidelines for its administration remain poorly defined.

To propose an anatomically informed protocol for safe and effective retrobulbar hyaluronidase injection in cases of filler-induced central retinal artery occlusion.
