Surgical scars after trepanotrabeculectomy

Trabeculectomy has proved to be superior to the classic filtering glaucoma operations. The final postoperative surgical scars should determine the most desirable technique. In this article, the scars observed in 73 eyes after primary trepanotrabeculectomy were followed up for two to eight years. Fifty-six of 73 eyes (80%) showed flat scars covered by normal conjunctiva without avascular cystic areas, no evidence of external filtration, and normalized intraocular tension. These scars did not impair the anatomic integrity of the eye and remained unchanged during the years.
