What Is Glaucoma?
3. Intraocular Pressure Buildup
It is not clear why the blockage or the buildup happens. However, studies suggest that there are hereditary causes. Other causes include trauma or chemical injury to the eye, inflammation, blockage of blood vessels in the eye, and infection. A medical procedure such as eye surgery can also lead to glaucoma.
In most cases, glaucoma affects both eyes, although it is usually worse in one eye.
