Glaucoma

Glaucoma is a problem with the eyes that harms the optic nerve. This nerve is like a superhighway that carries messages from your eye to your brain about what you see. If this nerve gets damaged, you can lose your vision, or even become blind.

Often, high pressure inside the eye is a factor in glaucoma. But, sometimes, glaucoma can happen even if your eye pressure seems normal. Glaucoma can affect people of any age, but it's more common in older adults. In fact, it's a major cause of blindness among those 60 and older.

A serious concern is that many types of glaucoma don't have noticeable symptoms at first. The vision loss happens so slowly that you might not realize anything is wrong until the problem is quite advanced. Regular eye exams are crucial. These exams usually include checking your eye pressure. Catching glaucoma early can help slow or even prevent vision loss.

If you have glaucoma, you'll need ongoing medical care and monitoring for the rest of your life. This might involve eye drops, special eye medicines, or other treatments to help control the condition.

Glaucoma symptoms vary depending on the type and how far it's progressed. In the early stages, there are often no noticeable symptoms.

As glaucoma progresses, you might start to notice small, blind spots in your peripheral vision (the area around the center of your sight).

Later stages of glaucoma can cause problems with your central vision. You may also experience a severe headache, severe eye pain, nausea, or vomiting. Blurred vision is another common symptom. You might see halos or colored rings around lights. Your eyes may also appear red.

Babies with glaucoma might have different signs. They may have a cloudy or dull-looking eye, increased blinking, or tears without crying. These babies need to be seen by a doctor quickly.

Other symptoms in adults and children can include:

• Blurred vision: This is a common symptom that can appear in various stages.
• Loss of peripheral vision: As glaucoma gets worse, you gradually lose the ability to see things to the sides of you.
• Nearsightedness that gets worse: If your nearsightedness suddenly worsens, it could be a sign of glaucoma.
• Headaches: These can be a symptom of glaucoma, especially in more advanced stages.
• Halos around lights: Seeing halos or rings around light sources is another possible symptom.
• Blurred vision with exercise: Some people notice their vision blurs more with physical activity.

If you experience sudden, severe symptoms like a bad headache and intense eye pain, it could be acute angle-closure glaucoma. This is a serious condition that requires immediate medical attention. Go to the emergency room or call an eye doctor (ophthalmologist) right away.

Sudden, severe symptoms could signal acute angle-closure glaucoma. This serious eye condition happens quickly and can cause a very bad headache and intense eye pain. If you experience these symptoms, it's crucial to get medical help immediately. Contact an ophthalmologist (eye doctor) or go to the nearest emergency room right away. Prompt treatment is essential.

Glaucoma is an eye condition where the optic nerve, which carries images from the eye to the brain, gets damaged. This damage leads to gradual vision loss, creating blind spots. Doctors aren't entirely sure why, but high eye pressure is usually a key factor.

High eye pressure happens when fluid inside the eye, called aqueous humor, builds up. Normally, this fluid drains through a special tissue called the trabecular meshwork, located at the junction of the colored part of your eye (iris) and the clear front surface (cornea). The cornea is crucial for clear vision, as it lets light into the eye.

There are different types of glaucoma, but the most common type is open-angle glaucoma. In this type, the drainage angle between the iris and cornea remains open, but other parts of the drainage system aren't working as well. This causes a slow, gradual increase in eye pressure.

Another type is angle-closure glaucoma. In this case, the iris bulges inward, partially or fully blocking the drainage angle. This prevents fluid from flowing out, leading to a buildup of pressure. This type of glaucoma can develop suddenly or over time.

Why the optic nerve is damaged when pressure is high isn't fully understood. It might be that the optic nerve is sensitive to pressure, or that it doesn't get enough blood flow. Limited blood flow can be caused by things like fatty deposits in the arteries (atherosclerosis) or other health problems.

Glaucoma can affect people of any age, including children. Babies can be born with it, or it can develop in early childhood. Possible causes include blocked drainage, injury, or an underlying health condition.

Pigmentary glaucoma is another type. Tiny pigment particles from the iris flake off and can clog or slow down the drainage of fluid, raising eye pressure. Activities like jogging can sometimes dislodge these particles, leading to a buildup.

Glaucoma tends to run in families. Scientists have found some genes that might be linked to higher eye pressure and optic nerve damage in certain people.

It's important to remember that this information is for general knowledge and does not replace advice from an eye doctor. If you have concerns about your vision, consult an ophthalmologist.

Glaucoma can harm your sight before you even realize anything is wrong. Knowing the risk factors can help you protect your eyes. Here are some things to be aware of:

• High eye pressure (intraocular pressure): This means the fluid inside your eye is under more pressure than normal. Too much pressure can damage the optic nerve, which sends signals from your eye to your brain.

• Age: Your risk of glaucoma increases as you get older, especially after age 55.

• Ethnicity: People of Black, Asian, or Hispanic descent have a higher chance of developing glaucoma.

• Family history: If someone in your family has glaucoma, you have a greater risk of getting it too.

• Health conditions: Certain medical problems like diabetes, migraines, high blood pressure, and sickle cell anemia can increase your risk. Having any of these conditions doesn't guarantee glaucoma, but it does make it more likely.

• Thin corneas: If the front part of your eye (the cornea) is thinner than average in the center, you might be at a higher risk.

• Strong vision problems: Very nearsighted or farsighted people may also have a higher risk.

• Eye injuries or surgery: An eye injury or certain types of eye surgery can sometimes raise your chances of developing glaucoma.

• Long-term steroid use: Using corticosteroid medications, particularly eye drops, for a long time can increase your risk. This is especially true for long-term use.

• Narrow drainage angles: Some people have a narrow angle where fluid drains from the eye. This can make them more susceptible to a type of glaucoma called angle-closure glaucoma. This is where the fluid drains out of the eye more slowly. If the drainage is slow, the fluid builds up and increases pressure.

Early Detection and Management of Glaucoma

Glaucoma is an eye condition that can lead to vision loss if not caught early. Taking these steps can help:

1. Regular Eye Exams: Getting regular eye exams is key to finding glaucoma early, before significant damage happens. The American Academy of Ophthalmology (AAO) suggests these general guidelines:

• Under 40: Every 5-10 years
• 40-54: Every 2-4 years
• 55-64: Every 1-3 years
• 65+: Every 1-2 years

However, if you have a family history of glaucoma or other risk factors, you might need more frequent checkups. Talk to your doctor about the best schedule for you.

2. Family History: Glaucoma often runs in families. Knowing your family's eye health history can help you understand your risk and determine how often you should be screened.

3. Eye Protection: Serious eye injuries can increase the risk of glaucoma. Always wear eye protection when using power tools or playing sports.

Billy Dowell Jr. has faced a challenging illness for many years. A serious immune-related condition has caused significant problems, including painful pelvic joint inflammation, a perforated bowel, and unfortunately, glaucoma. This ongoing illness has been extremely difficult for him. Billy, from Jacksonville, Florida, has been through a lot.

A doctor who specializes in eye care will review your medical history and perform a thorough eye exam. This exam will involve several different tests to get a complete picture of your eye health.

These tests might include:

• Checking for damage to the optic nerve: A special eye exam, where your pupils are dilated, and possibly some imaging tests, can help spot any problems with the optic nerve, the part of your eye that sends signals from your eye to your brain.

• Testing your overall vision: A visual field test checks for any areas where you might have trouble seeing. This helps pinpoint any potential vision loss. Think of it like mapping out the entire area you can see.

• Measuring the thickness of your cornea: A test called pachymetry measures the thickness of your cornea, the clear front part of your eye. This measurement is important for certain eye conditions.

• Checking the drainage angle of your eye: A test called gonioscopy looks at the angle where fluid drains from the eye. This is important for diagnosing and monitoring certain eye conditions, like glaucoma, which can affect the fluid drainage in your eye.
