The daily visual acuity,intraocular pressure(IOP), anterior chamber situation, and healing condition were measured at 1, 3, and 7 d, after con tact lens removal,.and 3 months after trabeculectomy..The conditions of blebs,.sensation of wearing contact lens,.and adverse events were recorded.Results:.Bleb leaks were observed at 2-8 d after surgery,(4.09±1.10 d on average). The daily Log MAR visual acuity did not significantly differ before and after contact lens wear(P>0.05). The IOP was significantly raised after at 1, 3, and7 d after lens wear.(all P <0.05).The IOP at 3 months after lens wear did not significantly differ from that measured at lens removal(t=1.191, P=0.089). At 1 d after lens wear, 6cases had deeper anterior chambers..All patients presented with a significantly deepened anterior chamber at 3 d after lens wear,.and were restored to the preoperative conditions..The bleb leakage was successfully treated at 7 d after lens removal in 10 patients, while 1 patient had to wear the contact lens for another 7 d for full healing of the bleb leak. No ocular infection was noted throughout the management.Conclusion: A soft bandage contact lens of 14 mm diameter is a safe and efficacious therapy for an early bleb leak following fornix-based trabeculectomy.展开更多

Trabeculectomy is the most commonly used glaucoma filtration surgery for glaucoma in the world. Conventional trabeculectomy is prone to anesthesia-related complications intraoperative and operationrelated complications postoperative in PCACG treatment. Modified minimally invasive trabeculectomy maybe can reduce the incidence of complications.Methods: We conducted a prospective case series study and performed modified fornix-based trabeculectomy in 27 patients(30 eyes) under topical anesthesia; we then observed intraoperative anesthesia and cooperation ef ect, intraoperative and postoperative complications, preoperative and postoperative visual acuity, intraocular pressure(IOP), visual field, and the use of ocular hypotensive drugs. The patients were followed up for at least 12 months.Results: All operations were completed successfully with no intraoperative complications. All 27 patients(30 eyes) were followed up for at least 12 months. No significant decrease in visual acuity was observed at days 1 or 7 and at months 1, 3, 6, and 12 after operation; however, a signii cant decrease in IOP was observed at days 1 and 7 and at months 1, 3, 6, and 12 after operation. Moreover, no significant progression in visual field mean defect was observed at month 12 after operation, and the number of ocular hypotensive drugs required was significantly reduced at months 6 and 12 after operation. By month 12 after operation, the overall success rate was 93.33%(28/30).Conclusions: Modii ed minimally invasive trabeculectomy is safe and ef ective for the treatment of PCACG.展开更多
