Purpose: Open-angle glaucoma (OAG) is a chronic, progressive, and irreversible multifactorial optic neuropathy. Characterized by an open angle of the anterior chamber, optic nerve head changes, and a gradual decline in peripheral vision followed by central visual field loss, OAG remains asymptomatic until advanced stages, emphasizing the critical need for early detection and management. Elevated intraocular pressure is a key risk factor for primary or secondary causes. Participating clinicians review the causes of OAG, pathophysiology, and the latest evidence-based strategies for evaluation and management in wetland areas. Design: This is a retrospective, observational study conducted in District Bandipora, Jammu and Kashmir, India. Method: This is a retrospective, observational study conducted in District Bandipora, Jammu and Kashmir, India. A total of 16,000 patients were screened at the hospital for various eye conditions. Of these, 224 patients were diagnosed with open-angle glaucoma and included in the study. Patients with other types of glaucoma, prior eye surgeries, or pre-existing ocular conditions were excluded. Results: Out of the 16,000 patients screened in the hospital over the 5-year period, 224 patients were diagnosed with open-angle glaucoma. Using the extrapolation formula, the estimated prevalence of open-angle glaucoma in the general population of District Bandipora was calculated to be 1.4%. Conclusion: This study demonstrates a higher-than-expected prevalence of open-angle glaucoma (1.4%) among individuals exposed to prolonged UV light in a high-altitude wetland area.
