PURPOSE: To compare fornix-based and limbal-based conjunctival flaps in trabeculectomy. CASES AND METHODS: Trabeculectomy with deep scleral tunnel was performed on 19 eyes. The series comprised 15 eyes of primary open-angle glaucoma and 3 eyes of secondary glaucoma. The conjunctival incision was fornix-based in 9 eyes and limbal-based in 9 eyes. Other surgical techniques, including scleral suture, were the same throughout. No eye received laser suturelysis. Findings: Intraocular pressure (IOP) before surgery averaged 27.7 ± 9.2 mmHg in fornix-based group and 26.8 ± 9.6 mmHg in limbal-based group. There was no significant difference between both groups. IOP during 1 to 6 months after surgery was consistently lower in limbal-based than in fornix-based group (p < 0.05). IOP 6 months after surgery averaged 12.9 ± 4.0 mmHg in fornix-based group and 8.6 ± 3.7 mmHg in limbal-based group. CONCLUSION: After trabeculectomy, better hypotensive effect was obtained by limbal-based than fornix-based conjunctival incision. LA: Japanese
