    Abstract:
    PURPOSE: To assess the success rate of the formation of functional filtration bleb in eyes undergoing different incision of conjunctiva flap after trabeculectomy. METHODS: To study the formation of functional filtration bleb after trabeculectomy, the result of trabeculectomy with the limbus based conjunctival flap in 165 eyes and the fornix based conjunctival flap in 207 eyes (372 eyes in 372 cases with primary glaucoma in total) was compared. RESULTS: All patients were observed after trabeculectomy in 1 week, but only 127 eyes were followed up in 3 months. In patients with trabeculectomy using the limbus based conjunctival flap, the success rate of the formation of the filtration bleb was 83.03% in 1 week and 78.69% in three months postoperatively, while in those using the fornix based conjunctival flap, the success rate was 55.07% in 1 week and 53.03% in 3 months. There was significant difference between the two groups in terms of the success rate of the formation of the filtration bleb. CONCLUSIONS: The result showed that limbus based conjunctival flap was especially effective and had better postoperative intraocular pressure decline.
