Eye of the illness
KOCHI: In our country, glaucoma is known to cause irreversible blindness in at least 12 million population affected by it, making near 1.2 million of them blind. However, over 90 % of cases remain undiagnosed. Glaucoma affects the optic nerve that connects our eyes to the brain. The clear fluid filling the eye, also known as aqueous humour, is constantly flowing in and out of the eye. Think of the eye as a sink with a tap that is always open.
