Introduction: The term micropulse laser trabeculoplasty suggests that only a fraction of the laser power is applied to the trabeculum to effect pressure lowering. It has not yet been exclusively used in Negroes, and we wish to report on our experience in Nigerian patients.
Methods: The study design is a retrospective chart review of our patients at the Rachel Eye Center in Abuja. The 810 diode Optos FastPulse laser was used to apply 34 cycles of treatment to 30 eyes of 16 individuals. Patients were selected based on the failure of maximal medical therapy. One patient had two extra rounds of treatment, while two patients were treated in only one eye. The pressure change at 1 hour after the treatment was analyzed. Patients were followed up for a mean period of 160 days with continuous monitoring of pressure changes. Patients' original therapy was not disturbed.
Results: Postlaser immediate drop in intraocular pressure (IOP) averaged 3.2 mmHg (CI 1.6-4.7, P<0.0001) representing 17.2% drop from baseline prelaser IOP. The drop in IOP was sustained over varying periods, from a few weeks to several months. There was a temporary spike in three instances. No serious side effects were noted.
Conclusion: Micropulse diode laser trabeculoplasty is a useful adjunct in the management of open-angle glaucoma in Nigerians. This corroborates the findings of other researchers in western populations.

Purpose: To evaluate the intraocular pressure (IOP)-lowering effect and safety of up to two bimatoprost implant administrations versus selective laser trabeculoplasty (SLT).
Design: Phase 3 (Stage 2), randomized, 24-month, multicenter, patient- and efficacy evaluator-masked, paired-eye clinical trial (NCT02507687).
Participants: Patients (n=183) with open-angle glaucoma or ocular hypertension inadequately managed with topical IOP-lowering medication for reasons other than efficacy.

Purpose Of Review: This review highlights new Federal Drug Administration (FDA) approved glaucoma treatments to familiarize providers with immediately available options.
Recent Findings: New FDA-approved treatments include the bimatoprost implant, travoprost implant, direct selective laser trabeculoplasty (DSLT), and ocular pressure adjusting pump. The bimatoprost implant is approved for a single administration with effects lasting for about 1 year, as opposed to the nearly 3-year effect for the travoprost implant.

In open-angle glaucoma, the increase in intraocular pressure (IOP) is caused by an increased resistance to aqueous humour outflow in the trabecular meshwork. Since genetic variability of matrix metalloproteinase (MMP) genes may influence extracellular matrix remodelling, we investigated their association with glaucoma risk and/or response to treatment. The retrospective part of the study included patients with primary open-angle glaucoma and ocular hypertension (OHT); in the prospective part of the study, newly diagnosed patients with POAG or OHT were randomised to receive either latanoprost or selective laser trabeculoplasty (SLT) as the initial treatment.
