Glaucoma – Causes and Symptoms  

Glaucoma is a condition that causes damage to your eye’s optic nerve and gets worse over time. It’s often linked to a buildup of pressure inside your eye. Glaucoma tends to be inherited and may not show up until later in life. Glaucoma is one of the leading causes of blindness for people over the age of 60. It can occur at any age but is more common in older adults.

Many forms of glaucoma have no warning signs. The effect is so gradual that you may not notice a change in vision until the condition is at an advanced stage for Gynecologist in Sharjah.

Because vision loss due to glaucoma can’t be recovered, it’s important to have regular eye exams that include measurements of your eye pressure so a diagnosis can be made in its early stages and treated appropriately. If glaucoma is recognized early, vision loss can be slowed or prevented. If you have the condition, you’ll generally need treatment for the rest of your life.

There are many types of glaucoma and many theories about the causes of glaucoma, but the exact cause is unknown.

Causes

Glaucoma is the result of damage to the optic nerve. As this nerve gradually deteriorates, blind spots develop in your visual field. For reasons that doctors don’t fully understand, this nerve damage is usually related to increased pressure in the eye.

Elevated eye pressure is due to a buildup of a fluid (aqueous humor) that flows throughout the inside of your eye. This internal fluid normally drains out through a tissue called the trabecular meshwork at the angle where the iris and cornea meet. When fluid is overproduced or the drainage system doesn’t work properly, the fluid can’t flow out at its normal rate and eye pressure increases.

Open-angle Glaucoma

Open-angle glaucoma is the most common form of the disease. The drainage angle formed by the cornea and iris remains open, but the trabecular meshwork is partially blocked. This causes pressure in the eye to gradually increase. This pressure damages the optic nerve. It happens so slowly that you may lose vision before you’re even aware of a problem.

Angle-closure Glaucoma

Angle-closure glaucoma, also called closed-angle glaucoma, occurs when the iris bulges forward to narrow or block the drainage angle formed by the cornea and iris. As a result, fluid can’t circulate through the eye and pressure increases. Some people have narrow drainage angles, putting them at increased risk of angle-closure glaucoma.

Angle-closure glaucoma may occur suddenly (acute angle-closure glaucoma) or gradually (chronic angle-closure glaucoma). Acute angle-closure glaucoma is a medical emergency.

Glaucoma in children

It’s possible for infants and children to have glaucoma. It may be present from birth or develop in the first few years of life. The optic nerve damage may be caused by drainage blockages or an underlying medical condition.

Signs & Symptoms

The signs and symptoms of glaucoma vary depending on the type and stage of your condition, such as:

Open-angle Glaucoma

Patchy blind spots in your side     (peripheral) or central vision, frequently in both eyes

Tunnel vision in the advanced     stages

Acute Angle-closure Glaucoma

Severe headache

Eye pain

Nausea and vomiting

Blurred vision

Halos around lights

Eye redness

Risk Factors

Because chronic forms of glaucoma can destroy vision before any signs or symptoms are apparent, be aware of these risk factors:

High internal eye pressure

Being above the age of 60

Family history of glaucoma

Having certain medical conditions,     such as diabetes, heart disease, high blood pressure & sickle cell     anemia

Having corneas that are thin in     the center

Being extremely nearsighted or     farsighted

Having had an eye injury or     certain types of eye surgery

Taking corticosteroid medications,     especially eye drops, for a long time

Prevention

These self-care steps can help you detect glaucoma in its early stages, which is important in preventing vision loss or slowing its progress.

Get Regular Dilated Eye Examinations: Regular comprehensive eye exams     can help detect glaucoma in its early stages, before significant damage     occurs. It is recommended by the Ophthalmology Doctors to have a     comprehensive eye exam every five to 10 years if you’re under 40 years old;     every two to four years if you’re 40 to 54 years old; everyone to three     years if you’re 55 to 64 years old; and everyone to two years if you’re     older than 65. If you’re at risk of glaucoma, you’ll need more frequent     screening. Ask your Eye Specialist to recommend the right screening     schedule for you.

Know Your Family’s Eye Health     History: Glaucoma     tends to run in families. If you’re at increased risk, you may need more     frequent screening.

Exercise Safely: Regular, moderate exercise may     help prevent glaucoma by reducing eye pressure. Talk with your doctor     about an appropriate exercise program.

Take Prescribed Eye drops Regularly: Glaucoma eye drops can     significantly reduce the risk that high eye pressure will progress to     glaucoma. To be effective, eye drops prescribed by your doctor need to be     used regularly even if you have no symptoms.

Wear Eye Protection. Serious eye injuries can     lead to glaucoma. Wear eye protection when using power tools or playing     high-speed racket sports in enclosed courts.

When to See an Eye Specialist?

Promptly consult an eye doctor (ophthalmologist) if you experience some of the symptoms of acute angle-closure glaucoma, such as severe headache, eye pain and blurred vision. Remember, if left untreated, glaucoma will eventually cause blindness. Know more visit Internal Medicine Doctor.
