Opportunistic screening – The key to prevent glaucoma-related blindness

Objectives: Glaucoma is characterised by progressive optic neuropathy and irreversible blindness. Patients with glaucoma usually seek advice only in the advanced stages due to its asymptomatic nature. Hence, it is of utmost importance to diagnose the disease early and conduct screening and awareness programmes, especially for the population at higher risk. Materials and Methods: This was a cross-sectional community-based study carried out in various old age homes and senior citizen clubs in a metro city of Western India during World Glaucoma Week 2024. Glaucoma screening was performed, and awareness and counselling sessions were conducted for these senior citizens. Results: Out of 205 senior citizens screened, 64 were referred for a detailed glaucoma evaluation and 59 for cataract and retina assessment. Only 22 persons sought consultation, of which six were found to be glaucoma suspects, two had primary open-angle glaucoma, one had secondary open-angle glaucoma, and one was a post-trabeculectomy patient with absence of follow-up. All these citizens were managed and counselled appropriately with an emphasis on compliance and lifelong monitoring. Conclusion: Despite glaucoma being the second leading cause of irreversible blindness worldwide, awareness is lacking among the general population. The elderly age group, although at a higher risk, is usually unaware of the need for screening and follow-up and sometimes also does not have the necessary resources or assistance. Opportunistic screening and education about glaucoma are the key factors which can help in early detection of the disease and prevention of blindness.
