Iatrogenic vision loss following aesthetic treatment with hyaluronic acid-containing filler: Every injector should be prepared.

Facial aesthetic enhancement with a hyaluronic acid-containing filler is a minimally invasive procedure that is considered rather safe.

This paper summarizes casuistic experiences to reverse these catastrophic complications, as specific evidence-based guidelines are currently not available.
