Diabetic retinopathy is caused by damage to the blood vessels in the tissue at the back of the eye (retina). Poorly controlled blood sugar is a risk factor.

While treatment can slow stop the progression of diabetic retinopathy, it's not a cure. Because diabetes is a lifelong condition, future retinal damage and vision loss are still possible. Even after treatment for diabetic retinopathy, you'll need regular eye exams. At some point, you might need additional treatment.

We have moved to 62 Hoog street Polokwane due to relocating our telephone lines have not been connected please call us on 0817021575 for appointments and queries. Sorry for the inconvenience.

Causes

Most cataracts develop when aging or injury changes the tissue that makes up the eye's lens. Proteins and fibers in the lens begin to break down, causing vision to become hazy or cloudy.

Some inherited genetic disorders that cause other health problems can increase your risk of cataracts. Cataracts can also be caused by other eye conditions, past eye surgery or medical conditions such as diabetes. Long-term use of steroid medications, too, can cause cataracts to develop.

How a cataract forms

A cataract is a cloudy lens. The lens is positioned behind the colored part of your eye (iris). The lens focuses light that passes into your eye, producing clear, sharp images on the retina — the light-sensitive membrane in the eye that functions like the film in a camera.

As you age, the lenses in your eyes become less flexible, less transparent and thicker. Age-related and other medical conditions cause proteins and fibers within the lenses to break down and clump together, clouding the lenses.

As the cataract continues to develop, the clouding becomes denser. A cataract scatters and blocks the light as it passes through the lens, preventing a sharply defined image from reaching your retina. As a result, your vision becomes blurred.

Cataracts generally develop in both eyes, but not always at the same rate. The cataract in one eye may be more advanced than the other, causing a difference in vision between eyes.

What are cataracts?

you’re over 60 and your vision has gotten blurry or cloudy, you may have cataracts. It’s a common condition in older adults, and it can be treated by your eye doctor.Children can also have cataracts.

What Are the Symptoms?

Cataracts usually form slowly. You may not know you have them until they start to block light. Then, you might notice:

Vision that’s cloudy, blurry, foggy, or filmy
Nearsightedness (in older people)
Changes in the way you see color
Problems driving at night (glare from oncoming headlights, for example)
Problems with glare during the day
Double vision in the affected eye
Trouble with eyeglasses or contact lenses not working well

Risk factors

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

Having high internal eye pressure (intraocular pressure)
Being over age 60

Being black, Asian or Hispanic

Having a family history of glaucoma
Having certain medical conditions, such as diabetes, heart disease, high blood pressure and 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 eyedrops, for a long TIME.

Preventing vision loss or slowing its progress.

Regular comprehensive eye exams can help detect glaucoma in its early stages, before significant damage occurs.

As a general rule, having 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; every one to three years if you're 55 to 64 years old; and every one to two years if you're older than 65. If you're at risk of glaucoma, you'll need more frequent screening.Your doctor will 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 eyedrops regularly. Glaucoma eyedrops can significantly reduce the risk that high eye pressure will progress to glaucoma.

To be effective, eyedrops 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.

More on the different kinds of Glaucoma

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.

Normal-tension glaucoma

In normal-tension glaucoma, your optic nerve becomes damaged even though your eye pressure is within the normal range. No one knows the exact reason for this. You may have a sensitive optic nerve, or you may have less blood being supplied to your optic nerve. This limited blood flow could be caused by atherosclerosis (the buildup of fatty deposits (plaque) in the arteries) or other conditions that impair circulation.

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.

Symptoms of Glaucoma

The signs and symptoms of glaucoma vary depending on the type and stage of your condition. For example:

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

If left untreated, glaucoma will eventually cause blindness. Even with treatment, about 15 percent of people with glaucoma become blind in at least one eye within 20 years.

Glaucoma the thief of sight

If you lose vision, it can’t be brought back. But lowering eye pressure can help you keep the sight you have. Most people with glaucoma who follow their treatment plan and have regular eye exams are able to keep their vision.

What Is Glaucoma?

Glaucoma is a condition that damages your eye's optic nerve. It gets worse over time. It's often linked to a buildup of pressure inside your eye. Glaucoma tends to run in families. You usually don’t get it until later in life.

The increased pressure in your eye, called intraocular pressure, can damage your optic nerve, which sends images to your brain. If the damage worsens, glaucoma can cause permanent vision loss or even total blindness within a few years.

Most people with glaucoma have no early symptoms or pain. Visit your eye doctor regularly so they can diagnose and treat glaucoma before you have long-term vision loss.
