Severe ocular complications following facial calcium hydroxylapatite injections: Two case reports

Dermal soft-tissue augmentation using a filler is a technique widely used for facial cosmetic enhancement. However, potential complications following facial cosmetic injections have heightened the possibility of iatrogenic visual loss. We report two cases of severe ocular complications after nasal cosmetic enhancement. Both cases had poor visual outcomes in spite of emergency management. The second patient is a rare case with bilateral anterior ischemic optic neuropathy after dermal soft-tissue augmentation. The visual outcome was correlated with the location and the extent of the arterial embolization. Unfortunately, there is still no standard treatment protocol for vision-threatening complications. Clinicians should always keep in mind that embolic arterial occlusion may occur after augmentation.
