Glaucoma is a group of eye condition that damages the optic nerve (nerve connecting the eye to the brain), usually due to high pressure in the eye. The increased pressure in the eye (intraocular pressure) can damage the optic nerve. If the damage worsens, glaucoma can cause permanent vision loss or even total blindness within a few years.
Glaucoma mostly affects adults over 40 years, but young, adults and even infants can suffer from this.
There are two main types of Glaucoma:
OPEN ANGLE GLAUCOMA:
This is the most common type of Glaucoma, also known as wide-angle Glaucoma. In this type of Glaucoma, the drain structure in an eye (the trabecular meshwork) looks fine, but fluid does not flow it should.
ANGLE CLOSURE GLAUCOMA:
This type of Glaucoma is also known as acute or chronic angle-closure or narrow-angle Glaucoma. In this type of Glaucoma, the eyes don’t drain like it should because the drain space between the iris and cornea becomes too narrow. It is also linked to farsightedness and cataracts, a clouding of the lens inside the eye.
