Glaucoma

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 intra ocular pressure (IOP) although it may occur with normal IOP (Normal Tension Glaucoma) & even with low IOP (Low Tension Glaucoma). The raised intra ocular pressure (IOP) is caused by the imbalance between the production and drainage of aqueous in the anterior chamber of the eye.
