Argon laser phototherapy of phthiriasis palpebrarum.

Argon laser phototherapy is an alternative new, quick, and effective method of treating phthiriasis palpebrarum in one sitting. A beam at a setting of 200-microns size, 0.1 second time, and 200 mW power is employed to destroy individual adult parasites and nits. The only drawbacks are an occasional but tolerable stinging and the slicing of the eyelash stems carrying the nit. The eyelashes regain their normal length within a few days.
