Glaucoma and cataract are eyepathology that can cause loss of vision. These diseases are slowly progressing. The pathophysiology of these diseases is not the same. Glaucoma is linked to long term build-up of pressure in the eye.
This leads to the damage of the optic nerve. If left untreated, this will eventually lead to visual field loss due to lack of communication between the retina and the brain, which leads to blindness. A cataract is the including of the lens of the eye. It gets worse over time, and it gradually leads to a decrease in vision as it gets worse.
A cataract is known to be changed in the lens of the eye. This would make the lens of the eye become more cloudy so the light will not have the ability to enter the eye properly. There are some people who undergo surgery in order to cure this condition.
Glaucoma is known to be the condition wherein there is a buildup in the pressure of the eye. When there is too much pressure, some issues may arise because they may cause some damage to the optic nerve. The optic nerve is in charge of sending signals to the brain so that the brain can start processing the information that it gets.
