A glaucoma is a group of eye diseases in which the optic nerve is damaged leading to irreversible loss of visual field. The optic nerve damage is caused by the raised intraocular pressure (IOP) although it may occur with normal IOP (Normal-Tension Glaucoma) & even with low IOP (Low Tension Glaucoma). The raised intraocular pressure (IOP) is caused by the imbalance between the production and drainage of aqueous in the anterior chamber of the eye.

Glaucoma is a condition of the eye where the optic nerve is affected due to various reasons and leads to partial to total vision loss if not treated. Often the main reason is abnormally high pressure in the eye. Glaucoma is one of the leading causes of blindness for people over the age of 60. It can occur at any age but is more common in older adults. Many forms of Glaucoma do not give any warning signs until it’s too advanced and often the progress is very gradual till its diagnosed and vision is affected. If glaucoma is diagnosed early, vision loss can be prevented. That’s why it is very important to have regular eye checkups. If diagnosed, generally the treatment is lifelong. Visual loss occurred due to Glaucoma is usually irreversible
