PURPOSE: To study the efficacy and safety of diode laser peripheral iridoplasty as a first-line treatment of acute primary angle-closure glaucoma (PACG) without the use of systemic anti-glaucoma medications. PATIENTS AND METHODS: Nine consecutive patients with acute PACG were recruited into the study. Each patient received topical pilocarpine (4%), timolol (0.5%), apraclonidine (1%), and immediate diode laser peripheral iridoplasty as primary treatment. Intraocular pressure (IOP) 15, 30, and 60 minutes after diode laser peripheral iridoplasty was documented by Goldmann applanation tonometry. RESULTS: The mean IOP of this group of patients was reduced from 66.3 ± 9.7 mmHg before diode laser peripheral iridoplasty to 36.6 ± 16.4 mmHg at 15 minutes, 26.3 ± 12.6 mmHg at 30 minutes, and 18.9 ± 8.4 mmHg at 60 minutes after diode laser peripheral iridoplasty. In seven of the nine patients, the corneal edema cleared up one hour after diode laser peripheral iridoplasty. In the remaining patient, the cornea cleared up 12 hours after diode laser peripheral iridoplasty. No significant complications were encountered. CONCLUSIONS: Diode laser peripheral iridoplasty, together with topical antiglaucoma medications without adjunctive systemic carbonic anhydrase inhibitors and hyperosmotic agents, appeared to be effective and safe in controlling the IOP in acute PACG.
