Question: what is glaucoma?

What Is Glaucoma?
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, you may be able to prevent additional vision loss.

Question: What are the usual symptoms of glaucoma?

The most common type of glaucoma is primary open-angle glaucoma. It has no signs or symptoms except gradual vision loss. For that reason, it's important that you go to yearly comprehensive eye exams so your ophthalmologist, or eye specialist, can monitor any changes in your vision.
Acute-angle closure glaucoma, which is also known as narrow-angle glaucoma, is a medical emergency. See your doctor immediately if you experience any of the following symptoms:
severe eye pain
nausea
vomiting
redness in your eye
sudden vision disturbances
seeing colored rings around lights
sudden blurred vision

Question: causes of glaucoma?

The back of your eye continuously makes a clear fluid called aqueous humor. As this fluid is made, it fills the front part of your eye. Then, it leaves your eye through channels in your cornea and iris. If these channels are blocked or partially obstructed, the natural pressure in your eye, which is called the intraocular pressure (IOP), may increase. As your IOP increases, your optic nerve may become damaged. As damage to your nerve progresses, you may begin losing sight in your eye.
What causes the pressure in your eye to increase isn't always known. However, doctors believe one or more of these factors may play a role:
dilating eye drops
blocked or restricted drainage in your eye
medications, such as corticosteroids
poor or reduced blood flow to your optic nerve
high or elevated blood pressure

Question: What are the potential risk factors associated with glaucoma?

According to the World Health Organization
(WHO), glaucoma is the second leading cause of blindness around the world. The risk factors for glaucoma include:
Age
People over 60 are at increased risk of glaucoma, warns the NEI
, and the risk of glaucoma increases slightly with each year of age. If you're African-American, your increase in risk begins at age 40.
Ethnicity
African-Americans or people of African descent are significantly more likely to develop glaucoma than Caucasians. People of Asian descent are at a higher risk of angle-closure glaucoma, and people of Japanese descent have a higher risk of developing low-tension glaucoma.
Eye Problems
Chronic eye inflammation and thin corneas can lead to increased pressure in your eyes. Physical injury or trauma to your eye, such as being hit in your eye, can also cause your eye pressure to increase.
Family History
Some types of glaucoma may run in families. If your parent or grandparent had open-angle glaucoma, you're at an increased risk of developing the condition.
Medical History
People with diabetes and those with high blood pressure and heart disease have an increased risk of developing glaucoma.
Use of Certain Medicine
Using corticosteroids for extended periods may increase your risk of developing secondary glaucoma.

Question: How do doctors usually figure out if someone has glaucoma, diagnosis?

To diagnose glaucoma, your ophthalmologist will want to perform a comprehensive eye examination. They'll check for signs of deterioration, including loss of nerve tissue. They may also use one or more of the following tests and procedures:
Detailed Medical History
Your doctor will want to know what symptoms you've been experiencing and if you have any personal or family history of glaucoma. They'll also ask for a general health assessment to determine if any other health conditions may be impacting your eye health, such as diabetes or high blood pressure.
Tonometry Test
This class of tests measures your eye's internal pressure.
Pachymetry Test
People with thin corneas have an increased risk of developing glaucoma. A pachymetry test can tell your doctor if your corneas are thinner than average.
Perimetry Test
This test, also known as a visual field test, can tell your doctor if glaucoma is affecting your vision by measuring your peripheral, or side, vision and your central vision.
Monitoring Your Optic Nerve
If your doctor wants to monitor for gradual changes to your optic nerve, they may take photographs of your optic nerve to conduct a side-by-side comparison over time.

Question: What are the ways to prevent glaucoma?

Glaucoma can't be prevented, but it's still important to catch it early so you 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. Make an appointment with an ophthalmologist. Simple tests performed during these routine eye checks may be able to detect damage from glaucoma before it advances and begins causing vision loss.
