Glaucoma is an eye disease that can damage your optic nerve. The optic nerve supplies visual information to your brain from your eyes. Glaucoma is usually, but not always, the result of abnormally high pressure inside your eye. Over time, the increased pressure can erode your optic nerve tissue, which may lead to vision loss or even blindness. If it’s caught early, one may be able to prevent additional vision loss.
The back of the eye continuously makes a clear fluid called aqueous humor. As this fluid is made, it fills the front part of the eye. Then, it leaves the eye through channels in the cornea and iris. If these channels are blocked or partially obstructed, the natural pressure in the eye, which is called the intraocular pressure (IOP), may increase. As IOP increases, optic nerve may become damaged. As damage to nerve progresses, one may begin losing eyesight. What causes the pressure in the eye to increase isn’t always known. However one or more of these factors may play a role:
Five major types of glaucoma exist:
Any personal or family history of glaucoma to determine if any other health conditions may be impacting your eye health, such as diabetes or high blood pressure.
Measures intra ocular pressure.
Done to measure corneal thickness.
This test, also known as a visual field test. This test is done to measure the peripheral, side and central vision.
This is done to find out the level of damage to the optic nerve.
The goal of glaucoma treatment is to reduce IOP to stop any additional eyesight loss. Treatment options include:
Several medicines are designed to reduce IOP. These medicines are available in the form of eye drops or pills, but the drops are more commonly used or a combination of these.
If a blocked or slow channel is causing increased IOP, surgery to maybe needed to drain the path for fluid or destroy tissues that are responsible for the increased fluid.
A laser procedure called laser peripheral iridotomy may also be performed for narrow angle glaucoma patients. This procedure creates small holes in the iris to allow for increased fluid movement.
If increased in IOP can be stopped and the pressure returned to normal, vision loss may be slowed or even stopped. However, because there’s no cure for glaucoma, one may likely need treatment for the rest of the life to regulate IOP. Unfortunately, vision lost as a result of glaucoma cannot be restored. Glaucoma can’t be prevented, but it’s still important to catch it early so that one can begin treatment that will help prevent it from getting worse. The best way to catch any type of glaucoma early is to have an annual preventive eye care appointment.
