Background: Autologous fat injection is getting popular in cosmetic procedures, however, still has a risk of fat embolism. Herein, we report the first case of segmental ischaemic infarction of the iris, which occurred after autologous fat injection into the lower eyelid.
Case presentation: A 28-year-old Korean woman complained of the discolouration of the iris after the fat injection. Slit-lamp biomicroscopy revealed segmental depigmented atrophic iris with sectoral sphincter palsy.
Conclusions: We found that iris atrophy could be caused by autologous fat transplantation. The plastic surgeons should pay more attention to possibility of fat embolism-induced ocular complications in the procedure of fat injection.
