Abstract:
The treatment of trichiasis has consistently posed a challenging therapeutic issue. A variety of treatment methods have been explored, each yielding different levels of success.We report our experience with the use of Argon laser photocoagulation for the treatment of recurrent trichiasis. A total of 30 lids (of 22 patients) with aberrant lashes were treated in our study. Each lash was treated with a beam of 50-200 microns (spot size), 0.2 s (time), and 0,7-1.2 watts (power). Neither infiltration nor topical anesthesia was used. The follow-up period averaged 6 months, with appointments scheduled for the 4th week, the 3rd month, and the 6th month. After the laser session, 80% of the eyelids were successfully treated with no signs of the condition reappearing. The remaining 20% of the eyelids needed more than one session to completely eliminate the recurrence of the condition. There was a significant correlation between the number of aberrant lashes per lid and the number of required laser sessions. Complete healing of the treated areas occurred within four weeks after treatment, with no vascularization or distortion of the lid margin. Argon laser treatment appears to be a safe and effective alternative to the other recognized methods of therapy in selected cases.
