Abstract

As a modality of effective treatment for trichiasis, authors performed experimental study of the radio frequency application(Mehl's method) to the cilia of four rabbit eyes with the different application times(10, 30, 60, 180 seconds). For the control, electrolysis to the cilia of the two eyes, and two eyes without any application were observed histopathologically. Regardless of the radio frequency application time, the radio frequency applied eyelids did not reveal any gross changes, and the selective degenerative changes(pyknotic, vacuolar, and karyorrhaxis) were observed microscopically in the hair regeneration part(internal root sheath of hair, hair matrix, and papillae of hair). In the electrolysed eyelids, gross scar and severe necrotic changes were appeared in microscopic findings. As a result of our observation, it is indicated that the application of radio frequency as a treatment for trichiasis, in compare with the electrolysis, revealed less destructive to the adjacent tissue, with more selective changes on the portion for hair regeneration.
