Aim: To report the safety and efficacy of Argon Laser Trabeculoplasty (ALT) in reducing intraocular pressure (IOP).Settings and Design: This was a retrospective study performed on 25 eyes of 25 patients.Methods and Materials: Consecutive patients who met the inclusion criteria for ALT were recruited from the ophthalmic clinic of the University College Hospital Ibadan, Nigeria and followed up for a minimum period of six months. Two criteria were used to define successful response. Criterion 1 was defined as IOP reduction of 3mmHgor more without additional intervention while criterion 2 was IOP reduction of 20% or more from the pretreatment IOPStatistical Analysis: Data was analyzed using SPSS version 16. Frequencies and means were generated to observe patterns of variable distribution among the patients. P value < 0.05 was considered significant.Results: The mean pretreatment IOP was 19.9 ±3.1mmHg, (range of 16 to 26 mmHg). Mean post treatment IOP at 6 months was 14.9 ±2.2 mmHg, (range of 11 to 19 mmHg). Mean IOP reduction at one year was 4.6 mmHg, representing a 22.3% drop. There was a statistically significant greater IOP reduction in eyes (P<0.001) with higherpretreatment IOP. Based on criterion 1 and 2, 84.0% of the patients had successful outcome at six months while at one year, 76.9% were successful based on criterion one.Conclusion: To the best of our knowledge, this is the first study to report the efficacy of ALT in Nigerians. ALT is safe and effective in reducing IOP in Nigerians.Key messages: ALT is safe and effective in reducing intraocular pressure in this population of NigeriansFunding: The present study did not receive any fundsKeywords: Argon laser trabeculoplasty, Nigerians, Primary open angle glaucoma, intraocular pressure, outcome

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.

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.
