Bleb Morphology and Related Complications: Ologen Versus Mitomycin - C in Primary Trabeculectomy: A Comparative Study

AIM: To assess and compare bleb morphology and its related complications in trabeculectomy with ologen implant and trabeculectomy with MMC. METHODS: In this study, 21 pateints of POAG underwent trabeculectomy with ologen implant (group A) and 21 patients of POAG underwent trabeculectomy with MMC (group B). Blebs were graded clinically with moorfields bleb grading system at 6 months. Early and late bleb related complications were noted at day 1 and 7, 4 week, 12 week and 6 month. RESULTS: The mean post operative bleb scoring was 4.38 � 0.67 in group A and 4.47 � 0.68 in group B. No significant difference between the two groups was found (p = 0.668 with 40 degrees of freedom). Early Bleb related complications were found in 14.28 % Patients in group A and 28.5 % patients in group B which was found to be non significant. ( p= 0.786). Postoperative mean ACD ( OCT) in group A and group B was 3.00+/- 0.16 and 3.14+/- 0.15 respectively and was found to be significant. (p=0.006). CONCLUSION: Bleb morphology and its complications were similar in both ologen implant and MMC in trabeculectomy.
