Glaucoma can be classified as a group of eye diseases in which vision can be partially or completely lost, sometimes without warning. Early glaucoma patients may not even be aware of the disease’s progress.
Ultimately, glaucoma damages the optic nerve leading from the eye to the brain, resulting in partial or complete blindness. While other factors may play a role in the disease’s development, chronic or acute increased intra-ocular pressure is commonly present, although some glaucoma patients maintain normal intra-ocular pressure.
Normally aqueous humor (fluid inside the eye) flows through channels to maintain eye health and function. In glaucoma patients this fluid becomes blocked.
