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.

The liquid flows through if the drainage mechanism is working well. But when it is blocked, the fluid accumulates and begins to exert pressure inside the eye, known as intraocular pressure (IOP). 
Over time, this high pressure (IOP) can damage delicate visual structures like the optic nerve head. If left untreated, it can turn you blind.
