OBJECTIVE: To investigate the clinical effect of transposing the conjunctival flap technique to thin-walled cystic blebs after trabeculectomy for the treatment of glaucoma. METHODS: Fifty-two eyes of 46 patients with thin-walled blebs underwent this modified operation. The procedure involved incising the conjunctiva surrounding the preserved bleb, then the conjunctiva-Tenon's fascia flap superior or temporal to the cystic flap was relaxed and mobilized to cover the bleb surface after topical cryopexy. The anterior margin of the flap was sutured onto the peripheral cornea. In order to relax the conjunctival flap sufficiently, an incision was made close to the superior fornix above the flap and parallel to the limbus in order to decrease tension. RESULTS: During the follow-up of between six months and four years, the mean intraocular pressure (IOP) in 52 eyes increased to 12.98 ± 5.70 mmHg postoperatively from 4.25 ± 1.33 mmHg preoperatively (1 mmHg = 0.133 kPa; t = 3.26; p < 0.01), 51 eyes maintained their filtering function. Postoperatively, bleb leakage in 20 eyes and macular edema in six eyes disappeared. Local antiglaucoma medication was required in one eye because the bleb disappeared with increasing IOP. Postoperative visual acuity was elevated compared to before operation (Χ2 = 16.65, p < 0.01). CONCLUSIONS: The transposing conjunctival flap technique is effective for the repair of thin-walled cystic blebs whose complications, such as hypotony, maculopathy, bleb leakage, or endophthalmitis, can be cured or prevented.
