ABSTRACT
To study the success rate of trabeculectomy by augmentation of filtering bleb by using C3F8 subconjunctivally during trabeculectomy in young patients having primary open angle glaucoma. Fifty patients both male and female aging between 36-47 years having primary open angle glaucoma were admitted for surgery. Patients in group-A underwent trabeculectomy only while the patients in group-B received an additional 0.5 ml of C3F8 subconjunctivaly at the end of trabeculectomy. Change in lOP was compared between the two groups. The mean lOP at the beginning of the study was 29.9 +/- 3.5 mmHg in group-A and 30.1 +/- 3.1mm in group-B. The maximum lOP in both groups was 33 mmHg and the minimum was 27mmHg. By the end of the study period at 24 weeks the lOP in group A was 23.5 +/- 8.65 mmHg and that in group B was 16.1 +/- 5.3 mmHg. Comparing the success and failure of the two procedures at the end of 24 weeks, it was found that 23 of the 25 patients [92%] in group-A qualified the criteria of success. Two of the 5 patients [8%] in this group had failure of lOP control. In group-B, 17 of the 25 patients were successful. 8 of the 25 patients [32%] could not meet the criteria of success. The augmentation of filtering bleb by using C3F8 subconjunctivally during trabeculectomy increases the total success rate of trabeculectomy in young patients having primary open angle glaucoma
