Trabeculectomy with Ologen implant versus perfluoropropane gas bubble for open angle glaucoma in pseudophakic eyes

Abstract

AIM: To evaluate the safety and efficacy of augmented trabeculotomy with Ologen versus perfluoropropane in management of pseudophakic glaucoma. METHODS: This is a comparative randomized study included 57 pseudophakic eyes of 57 patients with medically uncontrolled open angle glaucoma (OAG). Twenty-nine patients were allocated in group I (trabeculectomy with Ologen; trab-ologen group), while 28 patients were assigned in group II (trabeculectomy with perfluoropropane gas bubble; trab-C3F8 gas bubble group). RESULTS: The intraocular pressure (IOP) was significantly reduced in both study groups at all postoperative follow up intervals (1wk, 3, 6, 12, 18, 24, 30 and 36mo, P<0.001). The differences between the mean IOP values of both groups remained statistically insignificance during the early 12 months of follow up. However, the trab-ologen group achieved a statistically significant reduction over the trab-C3F8 gas bubble group during the last 24 months of follow up. CONCLUSION: Augmentation of trabeculectomy with either Ologen implant or perfluoropropane gas bubble are associated with strict long term IOP control and evident safety in medically-uncontrolled pseudophakic eyes with OAG.
