Abstract:AIM: To compare the clinical effects of two modes of conjunctival flap in trabeculectomy.
METHODS: In a randomized controlled clinical trial, 148 eyes 132 patients were divided randomly into two groups, the base in limbus of cornea conjunctival flap(group A)was 64 cases(72 eyes)and base in fornex(group B)was 68 cases(76 eyes). The follow-up time was 6-12 months to observe intraocular pressure, filtering bubble, anterior chamber depth and intraoperative and postoperative complications.
RESULTS: No statistically significant difference of the two modes of conjunctival flap on the postoperative success rate and postoperative IOP. The fornix base conjunctival flap(group B)can get a better bleb. Limbal base conjunctival flap(group A)showed more complications, such as late bleb leakage, hypotony.
CONCLUSION: The basement by the fornix conjunctival flap(group B)is better than the limbal base conjunctival flap(group A).
