Glaucoma is the leading cause of irreversible blindness in the world. Glaucoma is a disease in which the pressure inside the eye (intra ocular pressure/ IOP) rises gradually weakening the optic nerve. The optic nerve is the nerve responsible for vision thus once it is weakened it would lead to the gradual loss of vision and sometimes, total blindness. The fact that it is hardly known to the majority of population is truly a sad state of affair. In India around 12 million are affected of whom 1.1 million are blind. The illness is usually slowly progressing and patients are unaware of anything wrong with their eyes till significant visual loss has occurred. The initiative in glaucoma should be early diagnosis and prompt treatment with proper education of the patient regarding the grave nature of the disease. At Madurai Eye Center we have specialists in this sub-specialty with all the necessary equipments for diagnosing this disease, even at an early stage.
