Purpose: The aim of the present study was to determine the effects of mitomycin C (MMC) on eyelash regrowth in rats.
Methods: Ten rats were subjected to bilateral eyelid epilation. One drop of 0.04% MMC solution and one drop of normal saline was then administered to the right and left eyelid, respectively. Three months post-epliation, the number of regrown eyelashes was counted, and a section of tissue from each eyelid was examined under light- and electron microscopies.
Results: The number of regrown long eyelashes was 1.0 ± 0.81 on the right, and 12.5 ± 1.08 on the left. The rate of regrowth was 7.35 ± 5.55% on the right and 98.45 ± 3.27% on the left. Histological examination revealed no significant differences between the right and left eyelids, except for the absence of any hair shafts in the follicles on the right. However, electron microscopy revealed mitochondrial damage in the follicles of the right eyelid. These changes were not observed in tissue from the left eyelid.
Conclusions: The application of 0.04% MMC inhibited the regrowth of normal eyelashes in rats following simple epilation. These results suggest that MMC may be a novel therapy for replacing invasive surgery in trichiasis with no malpositioning.
