In addition to containing within itself several very important structures such as: iris, crystalline, vitreous, retina, optic nerve, etc., the globe of the eye also contains a liquid called aqueous humor. The aqueous humor provides the perfect optical transparency needed by the eye to function. In addition to supplying nutrients and eliminating waste substances, the aqueous humor is the main responsible for maintaining an ideal internal pressure in the eye, which allows the perfect functioning of vision.
The intraocular pressure depends on the balance between production and drainage of the aqueous humor, therefore a failure in the necessary drainage, causes an increase in the intraocular pressure above the normal limit, and that is what it is denominated Glaucoma.
The optic nerve is the most susceptible structure to an increase in intraocular pressure, since it can suffer irreversible damage after only a few brief periods of ocular hypertension.
Glaucoma, when diagnosed late or when treated incorrectly, always leads to loss of vision and even of the eyeball
