An estimated 1.3 crore people in the 30-60 age group are affected from glaucoma in India and of them 15.4 lakh have become blind. Unfortunately, unlike cataract, glaucoma is irreversible and usually asymptomatic. But, blindness due to glaucoma can be prevented with early treatment.
This makes it all the more important for early diagnosis through periodical screening of the target group, especially those who have a family history and people above 40 years. On detection, the patient has to invariably undergo the tests and treatment procedures suggested by a qualified ophthalmologist to arrest further deterioration of his/her vision, says medical coordinator and head of glaucoma and anterior segment, Sankar Foundation Eye Hospital, T. Raveendra.
Glaucoma is a disease that damages the eye’s optic nerve, which connects the eye to the brain, usually due to high eye pressure. It normally happens when fluid builds up in the front part of the eye. The extra fluid increases the pressure in the eye, damaging the optic nerve, Dr. Raveendra said in an interaction with The Hindu in connection with the World Glaucoma Week being observed from March 12 to 18.
“Glaucoma patients also compare themselves with cataract patients, who could see better after surgery, and feel that surgery has done no good to them as there is no improvement in their vision after surgery. They do not realise that surgery in their case would only arrest further progression of the disease but not reverse the damage that was already done.”
Free screening
Managing Trustee of Sankar Foundation K. Manimala underlined the importance of those beyond 40 years of age to visit a qualified ophthalmologist. “We are doing free screening for all the family members, if there is a known case of glaucoma in their family. We are also conducting all the required tests for others for Rs.100,” she added.
