Introduction/Aim. Argon Laser Trabeculoplasty (ALT) is a recognized method for reducing intraocular pressure (IOP) in patients with open angle glaucoma. The aim of this study was to compare the effects of primary medicament therapy and primary ALT on IOP regulation and stability of perimetry findings. Methods. A total of 50 eyes of 35 patients were treated with primary ALT while 50 eyes of 36 patients were treated with primary medicament therapy with 0.5% timolol with 20, 0.005% latanoprost 18 and with 2% dorzolamid 12 eyes. IOP was controled at 3 months, and the visual field at 6 months during a 30-month follow-up period. Results. In the first 24 months of follow-up there was no statistically significant difference in percentage of eyes with successfully regulated IOP. At 27th and 30th month, in the group primarily treated with medicaments a statistically significant higher percentage of successfully regulated IOP was observed in 98%, and 96% of the eyes, respectively, while in the group primarily treated with ALT the decline in the percentage of successfully regulated IOP was observed in 78% and 76% of the eyes, (?2-test, p = 0.002, p = 0.140). Both therapy groups showed stability of perimetry findings without statistically significant difference in the values of mean deviation (MD) index until the end of the monitoring period. The dynamics of change in MD index value showed a statistically significant greater decline in this parameter in subjects who had been primarily treated with medications during the last six months of follow-up, (two-factor analysis of variance with a repeated measurement, factor of time ? type of therapy, p = 0.030). Conclusion. Primary ALT equally successfully regulates IOP and restores stability of perimetry findings in patients with open angle glaucoma like the primary medicament therapy.

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.

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 compare the efficacy of the microwave pulse diode laser and argon laser trabeculoplasty in primary open angle glaucoma. Study Design:  Quasi experimental study. Place and Duration of Study:  Shaheed Mohtarma Benazir Bhutto Medical College Lyari and Sindh Government Lyari General Hospital, Karachi, from October, 2017 to March, 2018. Material and Methods:  One hundred and sixty patients, between 42 to 61 years with visual acuity of perception of light to 6/36 were enrolled. Patients diagnosed with POAG were included and patients with intraocular pressure of more than 40 mm Hg, previous glaucoma surgery or laser treatment and narrow angle on gonioscopy were excluded. Ophthalmic examination included visual acuity, slit lamp examination, fundus examination and visual field status using Humphrey perimeter. Patients were divided into two groups. Group A received microwave pulse diode laser (810) and Group B received argon laser trabeculoplasty. Average follow up period was 6 months. Success was assessed objectively by measuring intra ocular pressure and subjectively by visual acuity. Results:  The average time-period for each procedure was 15 ± 5 minutes. In Group A, mean IOP at first week, first month, third month and sixth month was 20.79, 16.34, 16.21and 16.09 mm Hg respectively. While in Group B, IOP at first week, first, third and sixth month was 16.52, 15.76, 13.62, and 12.54 mm Hg at (P < 0.001 in both groups). Conclusion:  Both microwave pulse diode laser and argon laser trabeculoplasty are effective in lowering intra ocular pressures in patients with primary open angle glaucoma.
