Introduction. Argon laser trabeculoplasty (ALT) is an intraocular pressure lowering method that is overall safe and powerful, but often complicated by transient postoperative intraocular pressure rises. In prevention of this complication, we frequently use two potent alpha-adrenergic agonists - brimonidine and apraclonidine. Objective. The aim of this study was to compare brimonidine 0.2% and apraclonidine 0.5% efficacy and safety in prevention of intraocular pressure elevation after ALT. Methods. This was a prospective, randomized, double-masked and comparative study. This study included 27 POAG patients, 15 received 0.2% brimonidine, and 12 received 0.5% apraclonidine before laser surgery (22 eyes in both groups). Intraocular pressure readings were taken 1, 2, 3, 24 hours and 7 days after ALT. Student?s t-test was used to analyze data between two groups, and ?2 test to compare data within groups. Value p less than 0.05 was considered statistically significant. Results. We found statistically significantly lower IOP in eyes that received 0.2% brimonidine at readings taken 1 hour after ALT (p=0.001). There were no statistically significant differences in other IOP readings between two groups. Conclusion. A single preoperative drop of brimonidine 0.2% had similar efficacy and safety as apraclonidine 0.5% in preventing transient IOP elevations after ALT.

Purpose: To assess efficacy and safety of argon laser trabeculoplasty (ALT) to lower intra ocular pressure (IOP) as adjunctive treatment in primary open angle glaucoma (POAG) patients. Study Design: Descriptive Cross Sectional. Place and Duration of Study: Ophthalmology Department, Abbassi Shaheed Hospital from May 2016 to August, 2017. Materials and Methods: Primary open glaucoma patients were selected from eye OPD. Patients with Inflammatory, angle closure, traumatic glaucoma were excluded. Pre laser and Post laser IOP was measured at 1st week then at 1, 3 and 6 months. Data was collected and analyzed on SPSS version 20. There were 114 patients Results: There were 69 (61%) male patients. Mean age of patients was 60.53 ± 10.71 years. Mean pre laser Intraocular pressure was 23.98 ± 10.01 mm Hg. Mean post laser IOP at one month was 15.6 ± 3.25 and at 6 months was 14.8 ± 3.28 mm Hg. Overall mean reduction of IOP was 9.18 mm Hg from baseline, with p value less than < 0.005. Pre laser 3 medications were used by 20 (18%) and 2 medications by 49 (43%). At 6 months follow-up 4 (3.5%) patients were on 3 medications and 31 (37%) were on 2 medications. It has a p value < 0.005. Drug free patients at 6 months follow-up were 37 (33%). Mild iritis was seen in 7 (6.14%) patients. Conclusion: Argon Laser Trabeculoplasty is effective and safe method to control IOP in POAG when used as an adjunct to medical therapy. It also decreases number of drugs used by patients. Key Words: Argon laser trabeculoplasty, intraocular pressure, primary open angle glaucoma.
