Partially Reversible Episode of Blindness after Intravascular Hyaluronic Acid Filler Injection.

Blindness from hyaluronic acid filler injections is an uncommon but devastating complication. We present a case of blindness related to a "skin booster." It is often assumed that skin boosters have no risk of visual problems, and this case underlines the need to understand products' rheology and chemistry. Given the lack of agreed consensus in bedside and secondary care management, it is important to report and describe all cases of vision loss caused by fillers, including assessment and management, to allow understanding of what may give rise to better outcomes.
