Glaucoma
Glaucoma is a condition which damages the optic nerve of your eye & worsens over times. It is associated with pressure buildup inside the eye, which is termed as "Intraocular Pressure". Continuous damage to the eye's optic nerve due to increased pressure sometimes leads to permanent loss of vision.
As people suffering from Glaucoma notice mild or no symptoms, it is advisable to regularly consult a good eye doctor so that this harrowing condition can be successfully diagnosed & treated before it is too late.
