Glaucoma 
Defination
Is a condition of an increased pressure of the eyeball with weakening of the optic nerve, causing gradually loss of sight and may lead to blindness.
Pathophysiology
The glaucoma are the group of optic neuropathic characterised by progressive degeneration of retinal ganglion cells. These are central nervous system neurons that have their bodies in the inner retina and axons in the optic nerve.
Glaucoma is the result of damage to the optic nerve. As this nerve gradually deteriorates, blind spots develop in your visual field. For reasons that doctors don't fully understand this nerve damage is usually related to increased pressure in the eye.
Glaucoma is caused by raised intra-ocular pressure. It is this raised pressure that compresses and damages the optic nerve. Once the optic nerve is damaged. It fails to carry visual information to the brain and this results in loss of vision.
