Abstract

The marginal epithelium of corneal ulcer is occasionally edernatous and detached from corneal stroma in chronic corneal ulcer. This leads to retard healing of corneal epithelium because the migration and adhesion of corneal epithelium are prevented. We performed Nd-YAG laser in chronic corneal ulcer, 6 eyes of 6 patients from July 1996 to December 1996. It was used to improve the healing of corneal epithelium. The patiente were treated with Nd-YAG laser using 0.8 to 1. 2mJ per pulse applied to the region of Bowman`s membrane in the margin of corneal ulcer. The mean number of laser spots in one procedure was 22 and the rnean frequency of Nd-YAG laser use in each patient was 2. 3 times. The Nd-YAG laser induced adhesion of corneal epithelium in all patients and improved the healing of corneal epithelium. Therefore, the treatment of Nd-YAG laser can become 8 useful procedure for chronic corneal ulcer accompanied with corneal epithelial detachment.
