Maintenance and repair of filtering bleb after trabeculectomy

This study is to investigate the methods of maintenance and repair of filtering bleb after trabeculectomy. 180 patients (210 eyes with glaucoma) with primary glaucoma were performed by trabeculectomy. In the early postoperative period, the functional filtering blebs of 130 patients (155 eyes with glaucoma) were maintained and the corresponding repair of dysfunctional filtering blebs for 50 patients (55 eyes with glaucoma) was performed. And the patients were followed up for 6 months to 4 years. In early stage after trabeculectomy, the maintenance of functional filtering bleb can make the patients’ intraocular pressure be controlled well, which can improve the surgical results. After repairing dysfunctional filtering blebs for 50 patients (55 eyes with glaucoma), the dysfunctional filtering blebs of 49 patients (54 eyes with glaucoma) were converted to functional filtering bleb, reaching 98.2%. Filtration surgery plays a significant role in the maintenance and repair of filtering bleb function of glaucoma patients. Functional repair in early stage after surgery can improve the success rate of the operation.
