The goal of this clinical trial is to compare the short-term efficacy and safety of selective laser trabeculoplasty (SLT) to 0.005% latanoprost eye drops in lowering intraocular pressure (IOP) as primary therapy in treatment-naïve patients diagnosed as early to moderate primary open-angle glaucoma(POAG) or ocular hypertension (OHT) in the Lagos State University Teaching Hospital, Ikeja. The main questions it aims to answer are: 1. Will Selective Laser Trabeculoplasty be an equally effective treatment option compared with 0.005% Latanoprost eyedrops in reducing Intraocular Pressure when used alone as first-line therapy in Nigerian patients with POAG and OHT? 2. Will Selective Laser Trabeculoplasty record a similar safety profile compared with 0.005% Latanoprost when used independently as a primary therapy? 3. How will the quality of life of patients who undergo Selective Laser Trabeculoplasty treatment compare with patients on 0.005% Latanoprost eyedrops? Participants will be randomized to one of the two intervention groups. Group A(latanoprost group) will use 0.005% latanoprost eye drops every night at 2100hours(9.00pm) west African Time for 3 months. intraocular pressures will be monitored at intervals for a period of 3 months. Group B(SLT group) will have Laser treatment administered as a one-off treatment. intraocular pressures will be monitored at intervals for a period of 3 months. A record of side effects will be documented at each follow up visit
