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.

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.

The Glaucoma Laser Trial (GLT) was a randomized, single-blind, controlled clinical trial comparing the efficacy and safety of argon laser trabeculoplasty (ALT) to treatment with topical medication for controlling intraocular pressure (IOP) in patients with newly diagnosed, previously untreated, primary open-angle glaucoma (POAG). The study showed that initial treatment of POAG with ALT is an efficacious and safe alternative to medication therapy, particularly in patients where medical therapy is contraindicated or poor compliance is suspected. The initial use of ALT in the short term has the benefit of reducing the nuisance, inconvenience, and systemic side effects of the topical glaucoma medication alternatives.

PURPOSE. To study the changes in structural and hemodynamic parameters of the retina and foveolar avascular zone (FAZ) over time in patients with primary open-angle glaucoma (POAG) and diabetes mellitus (DM) observed in long-term follow-up.MATERIALS AND METHODS. The study included 258 patients (258 eyes) divided into five groups: group 1 — 58 patients (58 eyes) with stage I POAG and DM; group 2 — 50 patients (50 eyes) with stage I POAG; group 3 — 50 patients (50 eyes) with stage III POAG and DM; group 4 — 50 patients (50 eyes) with stage III POAG; group 5 — 50 patients (50 eyes) with DM. Patients underwent comprehensive ophthalmological examination, spectral domain optical coherence tomography (SD-OCT), optical coherence tomo-graphy angiography (OCT-A) of the macular region. The follow-up lasted 24 months.RESULTS. Analysis of the initial parameters in groups of patients with comorbidities showed the lowest values compared to controls, which were progressively worsening. MD in the group with DM + stage I POAG had reliably decreased after 12 months (by 5.05%), after 24 months by 12.12% (p≤0.05). The speed of GCL+IPL loss in groups 1 and 3 during the first year of observation was almost equal for initial and advanced glaucoma — 1.35 (-2.03%) and 1.32 (-2.36%) µm/year, but in group 3 the loss had doubled after two years (2.48 (-4.44%) and 1.41 (2.12%) µm/year). Deterioration of hymodynamic parameters in the macular region in groups 1 and 3 was noted primarily in the inner sectors (whole image vessel density in parafovea (PF wiVD) -0.79% during the first, and -2.57% during the second year in initial glaucoma, -0.6% and -1.24% in advanced, whole image vessel density in parafovea (PF wiVD) -0.2% and -1.22%, -0.66% and -1.56%, respectively). Parameters of FAZ had changed significantly after 2 years in patients with stage I POAG and DM: its area size had increased by 10.2%, perimeter by 4.49%, circularity index had decreased by 3.17%.CONCLUSION. Comorbidity of POAG and DM is accompanied by development and quick progression of significant changes in structural and hemodynamic parameters of the retina as observed by this long-term follow-up.
