RÉSUMÉ
PURPOSE: To assess the surgical outcomes of the conventional trabeculectomy converted from DSCI due to a perforation of trabeculo-descemet's membrane during surgery. METHODS: We retrospectively analyzed the surgical outcomes of 9 patients (11 eyes) who underwent the conventional trabeculectomy converted from DSCI during surgery. RESULTS: The mean age of the subjects was 44.6+/-17.8 years. The types of glaucoma of the subjects were primary open angle glaucoma in nine eyes and secondary glaucoma in two eyes. The mean preoperative intraocular pressure(IOP) was 23.4+/-9.5mmHg with 3.0+/-1.2 of mean anti-glaucoma medications. The mean immediate postoperative IOP was 7.7+/-5.3mmHg and 10.5+/-3.9 mmHg with 0.5+/-0.5 of mean anti-glaucoma medications after 12.0+/-6.6 months of mean follow-up period. Defining the qualified success to be 6 to 21 mmHg of IOP with 2 or lower glaucoma medication without complications such as hypotony maculopathy, the success rate was 82%. There were four eyes (36%) having IOP below 4 mmHg and shallow anterior chamber at one day postoperatively. Two eyes of them recovered within 2 weeks, but the other two (18%) developed hypotony maculopathy. Cataract progressed in two eyes (18%). CONCLUSIONS: The surgical outcomes of conventional trabeculectomy converted from DSCI during surgery was comparable to the elective trabeculectomy, but there was a tendency to have more complications associated with hyperfiltration at the immediate postoperative period.
