Glaucoma can be treated in two key ways.
Glaucoma is a disease where the increase in intraocular pressure causes a damage to the optic nerve, which in turn leads to loss of peripheral vision. If uncontrolled, glaucoma could lead to irreversible blindness.
Inside the eye there is a constant production of fluid called aqueous humor. This fluid drains through very small channels in the anterior drainage angle located between the cornea (clear tissue in front of the color part of the eye) and the iris (the color part of the eye) and then flows out of the eye through the venous system. A decrease in drainage of the aqueous humor can lead to elevated intraocular pressures.
The most common type of glaucoma is called open angle glaucoma. In this case, there is a slow buildup of fluid within the eye, in which there is a normal drainage-angle depth that does not drain as it should, causing increased intraocular pressure and ultimately leading to damage of the nerve. There is also a type of glaucoma called normal tension glaucoma, in which the intraocular pressure is normal, yet the patient still develops glaucomatous damages (damage to the optic nerve).
In angle closure glaucoma, the anterior drainage-angle is narrow and there is decreased fluid outflow. Patients with narrow angles are at an increased risk of developing acute angle closure glaucoma, in which there is an abrupt increase in intraocular pressure with sudden decrease in vision and severe eye pain and headache. These patients feel so sick that they can even have nausea and vomiting.
