PURPOSE: To determine the efficacy of extensive microsurgical needling revision of failed filtering blebs followed by serial 5-fluorouracil subconjunctival injections. METHODS: Thirty-six eyes of 34 consecutive patients with progressive open-angle glaucoma refractory to topical therapy submitted to needling revision as a major procedure. All patients required multiple antiglaucoma medications preoperatively, and had completely flat or densely encapsulated filtering blebs. All patients underwent elaborate needling revision (limbus to superior rectus >8 mm diameter, >3 mm elevation, entry-site sutured with 8-0 vicryl and bleb reformed via paracentesis with viscoelastic) in the operating room, followed by serial 5-fluorouracil. The patients were followed for up to 6 months postoperatively. The main outcome measures were intraocular pressure (IOP) and the number of antiglaucoma medications used. RESULTS: Thirty-one eyes (86%) maintained mean IOP below 15 mmHg postneedling without medication. Overall the mean IOP postneedling was >9 mmHg lower than medicated preoperative levels (P < 0.0001). IOP reduction in encapsulated blebs was marginally superior to that in flat blebs. CONCLUSIONS: Extensive needling revision in the operating room is safe, straightforward, and produces reproducible restoration of filtering function.
