Filtration surgery (Trabeculectomy) is the main treatment for glaucoma. The scarring of the filtration bleb and obstruction of the outflow of aqueous humor through the filtration channel are the main reasons of the surgery failure. The objective of this study was to determine the clinical efficacy of needle revision of filtration blebs combined with subconjunctival injection of conbercept on the functional bleb formation in glaucoma patients with eye pressure out of control after trabeculectomy. A total of 48 eyes with poor filtration bleb function after trabeculectomy for glaucoma were treated with needle revision of filtration bleb combined with subconjunctival injection of conbercept. After the treatment, the patients were followed up for 3 months during which visual acuity, intraocular pressure, slit lamp and ultrasound biomicroscope examinations were performed. Intraoperative and postoperative complications were recorded. The visual acuity and intraocular pressure were significantly improved after the needle revision of filtration blebs. Among the 48 eyes, 39 eyes still had functional blebs at the end of the follow-up period, and filtration blebs failed in 9 eyes 2 to 8 weeks after the removal of the needle. The survival rate of filtration blebs at 3 months after needle revision was (79.06 ±â€…3.42%), and 81.25% (39/48) of the eyes showed good formation rate of functional bleb at the last follow-up. Three months after needle revision, there was local scar formation in some filtration blebs. Part of the filtration blebs showed mild thickening of the local subconjunctival tissue, and the filtration bleb was slightly raised and diffuse, showing a multi-cavity and thin-walled shape in some blebs. Ultrasound biomicroscopy examination showed relative structural manifestations. Subconjunctival hemorrhage occurred in 43 patients during and after the operation. Low intraocular pressure occurred in 8 patients with the lowest pressure of 5 mm Hg. Choroidal edema was observed in 3 patients. Five patients had intraoperative conjunctival hemorrhage in the anterior chamber, and hyphema occurred. All complications were self-limited and resolved without surgical intervention. Needle revision of filtration bleb combined with anti-VEGF drugs is a safe and effective method for the treatment of filtration bleb dysfunction after surgery of glaucoma.
