Introduction: Glaucoma is a multifactorial, chronic and progressive optic neuropathy that results in visual field defects and it is commonly associated with increased intraocular pressure. It is one of the most important causes of irreversible blindness left untreated. Objective: This study aims to assess awareness of glaucoma patients on the risk of development of glaucoma in close relatives and to determine the prevalence of glaucoma in close relatives. Methods: This is a self-designed questionnaire-based study with three sections consisting of demographic details and questions about knowledge and awareness of the patients. One hundred participants attending the ophthalmology outpatient department of a tertiary care hospital filled the questionnaire. Results: According to the responses obtained, 44 (44%) patients were unaware of the term glaucoma until they were diagnosed with the disease. Only 24(24%) patients had actual knowledge about glaucoma. It is also seen that positive family history is seen as a risk factor in only 30(30%) patients. Only 19(19%) of the patients urged their relatives to get screening to post their diagnosis out of which 7(36.8%) patients had one or more relatives diagnosed with glaucoma. Conclusion: Awareness can be increased by mass media announcements, health programs and Ophthalmologists at the time of diagnosis and follow up by educating diagnosed patients and also encouraging them to instruct their relatives to undergo screening. This creates positive health-seeking behaviour leading to early diagnosis and better prognosis of glaucoma.
