Retinal Ganglion Cell Neuroprotection Under Prostaglandin Analogues

Brief summary (registry, in English)

The goal of this observational study is to evaluate whether prostaglandin analogue eye drops have a direct neuroprotective effect on retinal ganglion cells - beyond their intraocular pressure (IOP)-lowering effect - in adult patients with glaucoma or ocular hypertension. The study includes individuals diagnosed with glaucoma (any sex/gender, adult age groups) undergoing standard clinical treatment. The main questions it aims to answer are: * Do prostaglandin analogues provide a neuroprotective effect on retinal ganglion cells that is independent of their IOP-lowering properties? * Should prostaglandin analogues be promoted/favoured over other IOP-lowering compounds for long-term glaucoma management? Researchers will compare an interventional group, which consist of 750 eyes treated with prostaglandin analogues (e.g., latanoprost, travoprost, tafluprost, bimatoprost, unoprostone), with a control group, which consist of 750 eyes treated with non-prostaglandin IOP-lowering compounds (e.g., timolol, dorzolamide, brimonidine, netarsudil) to see if treatment with prostaglandin analogues is associated with better retinal ganglion cell survival over a period of 3 years (36 months). Data will be collected from individuals who had at least 36 months of documented follow-up, with clinical data available at approximately 3, 6, 12, 24, and 36 months. Eligible individuals must have been treated with either prostaglandin analogues or other intraocular pressure (IOP)-lowering agents as part of routine clinical care. The data to be obtained from medical records will include at least: * Intraocular pressure readings * Visual field testing * OCT measures * Visual acuity * Adverse events * Treatment adherence/compliance * Additional glaucoma interventions
