Abstract
- We analyzed 72 eyes of 62 patients with various types of glaucoma who were able to follow up and had controlled intraocular pressure under 21 mmHg by trabeculectomy only, during the period of January 1, 1986 throungh June 31, 1989. The follow-up period was at least 1 year. The corrected visual acuity was reduced in 20 eyes(27.8%) at 3 months postoperatively, and 22 eyes(30.5%) at 1 year postoperatively. The refractive changes were increased myopia or decreased hyperopia in 40 eyes(55.6%) at 3 months postoperatively, and 42 eyes(58.3%) at 1 year postoperatively. There was no statistical significance in refractive change attributable to trabeculectomy procedures, but a tendency to change in the direction of increasing myopia or decreasing hyperopia was observed.
