PURPOSE: To evaluate the effectiveness of phacoemulsification and goniosynechialysis (PEGS) in managing acute and subacute primary angle closure unresponsive to conventional therapy. MATERIALS AND METHODS: Retrospective series of patients of six glaucoma-trained surgeons with primary angle closure that did not respond to medical management, Nd:YAG laser peripheral iridotomy, or argon laser peripheral iridoplasty. RESULTS: A total of twenty-one patients with an average age of 65.6 years were included. Underlying mechanism of angle closure included pupillary block (n = 18) and plateau iris (n = 3). Average intraocular pressure (IOP) immediately prior to PEGS was 40.7 mm Hg, and mean follow-up time after PEGS was 11.7 months. PEGS decreased mean IOP by 25 mm Hg (62%), and mean number of medications from 3.8 pre-surgery to 1.7 post-surgery (55%). Mean LogMar visual acuity improved after PEGS, from 0.64 to 0.44 (Paired t test t = 4.120 P = 0.001). Subsequent trabeculectomy was necessary in one case (5%). CONCLUSIONS: Phacoemulsification with goniosynechialysis may be an effective treatment option for primary angle closure unresponsive to conventional therapy.
