Glaucoma is an eye disease that can damage your optic nerve. The optic nerve is the nerve that supplies visual information to the brain from your eyes. If this nerve is damaged, the ability to see you will decrease. Glaucoma is a disease that causes permanent blindness that cannot be cured. Come on, learn what are the causes of glaucoma below.
What are the causes of glaucoma?
Eyeball pressure or intraocular pressure that is too high are the main factors causing glaucoma. High intraocular pressure (ocular hypertension) will cause damage to the optic nerve.
The high pressure of the eyeball will suppress the optic nerve located behind the eye. Over time these nerves can be damaged due to a decrease in blood flow to the eye nerve due to pressure.
Reporting from the WebMD page, normal intraocular pressure ranges from 10-21 mmHg. When this pressure is too low, the eyes will be too soft. Whereas if it is too high, the eyes become too hard and then become the main factor of glaucoma.
Apart from eye pressure, there are several other conditions that can also trigger glaucoma:
- Non-fluent blood flow to the optic nerve or blockage of the blood vessels of the eye
- Injury due to exposure to chemicals in the eye
- Severe eye infections and inflammation
- Use of corticosteroid drugs
What causes the eyeball pressure to increase?
What causes the pressure in the eye to increase is actually not known with certainty. However, doctors believe there are several factors that play a role in this condition. The most important thing is the clogging of fluid drainage in the eyeball, while excessive fluid production. The exact cause of blockage of fluid drainage in the eyeball is also unknown.
Allegedly, a high eye pressure caused by a channel that normally drains fluid from the eye does not function properly. More liquid eyeballs continue to be produced but not removed so that the eyeball pressure increases. Just imagine like a balloon filled with water, the more water the higher the pressure.
According to doctors, blockage of this drainage is genetic. That is, the nature of the eyeball like this is passed from the parent to the child. Less commonly reported causes are the presence of an eye injury due to a blunt impact or exposure to chemical substances in the eye, severe eye infections, inflammation of the eye, and the result of eye surgery.
