Glaucoma is a chronic, progressive optic neuropathy caused by a group of eye diseases that lead to damage to the optic nerve head and a change in visual field. The most common risk factor generally acknowledged is a rise in intraocular pressure. Quite a few times secondary glaucoma goes undiagnosed. WHO states that over 7.7 million persons with glaucomatous optic neuropathy are thought to exist in the globe. This was a hospital based Clinical cross-sectional study. The aim of my study is to Prevent blindness due to secondary glaucoma. This was an OPD based study which consisted of 105 patients of secondary glaucoma. The duration of the study was for 18 months, it was conducted on patients aged 25- 80 yrs, Examinations were performed by direct and indirect ophthalmoscopes, gonioscopy was performed, the patients treatments were tailored to each individual. This study found that maximum number of patients belonged to the age group between 61-70yrs that is (21%) followed by 51-60yrs having (19%), 41-50yrs having (16.2%), 71- 80yrs & 20-30yrs having (15.2%) and 31-40 having the least amount of patients i.e.(13.2%). The study concluded that secondary glaucoma is very common in the older age and low socioeconomic group as they tend to prolong the treatment for cataract and in the end lead to secondary angle closure glaucoma.
