Complications associated with infraorbital filler injection

Soft tissue augmentation with injectable fillers is increasingly being performed, and providers must be prepared to understand and treat complications. Periorbital skin presents unique challenges due to its thin nature, easily evident pigmentary and textural irregularities, and anatomical considerations including vasculature and subcutaneous layers. The most common complications of infraorbital filler include ecchymosis, malar edema, blue-gray hue, and contour irregularities. Uncommon complications include infection and biofilm formation, skin necrosis, and blindness. This purpose of this review is to highlight the infraorbital anatomy, complications of filler injection in this region, and techniques to avoid these complications.
