There are three principal diseases caused by diabetic eye disorders.
They include the following diabetic eye disorders:
During the following article we’re going to give a brief overview of each of the diabetic eye disorders.
Retinopathy damages small blood vessels which transport oxygen and nutrients to the retina. The retina enabes a person to sense light and is located in a circular lining at the back of the eyeball.
There are types of retinopathy referred to as proliferative and nonproliferative.
Nonproliferative retinopathy involves the enlargement, bulging, and pouch formation of these small blood vessels. The end results is both a weakening of the blood vessel along with a leaking of fluid. In it’s worst stages, larger amounts of fluids, blods, and fats can be leaked. This causes the retina to swell.
Usually swelling will not harm your eye sight unless it involves the center, called the macula. Macular edema refers to swelling in the center portion.
Proliferative retinopathy involves small blood vessels which have become so damaged that they close off. When this occurs, new blood vessels grow and branch off to other areas of the eye. One of two things can happen in this instance:
- No change in your eye sight.
- You begin having trouble seeing in your peripheral sight and adjusting to light.
Should the new blood vessels be weak, they can cause problems. They can break and begin bleeding into the clear gel that fills the center of the eye. This condition is known as a vitreous hemorrhage. Blurring and floating spots are signs of a vitreous hemorrhage. You can lose your sight if this is not treated.
Another problem that could occur is a detached retina. This is caused by scar tissue growing on the retina and pulling it out of place. If this occurs, your will start seeing shadows or large dark areas.
Cataracts cloud the lenses of the eye.
They normally start out small and then tend to block light from entering the retina. Your lens is normally clear and lies behind the iris (the colored part of your eye) and the pupil (the dark opening.)
There are three factors which determine how a cataract will affect your sight:
- How large or small the cataract is.
- How thin or think it is.
- Where it is located on the lens.
Symptoms of cataracts:
- Sight is hazy, fuzzy, or blurry.
- You think you need new glasses.
- Your new glasses do not help.
- It becomes difficult to read.
- Excessive bleeding.
- Feel like a film is covering your eyes.
- Sensation of looking through a cloudy glass.
- Colors look dull.
Glaucoma is a buildup of fluid in the eye.
This fluid buildup causes and increase in pressure which damages the optic nerve. The optic nerve is important because it tells our brain what our eyes are seeing.
There are two types of glaucoma:
- Chronic open-angle glaucoma is the most common. In this type, fluid pressure rises slowly over many years. You may feel increased eye pressure or a tearing sensation. A symptom of this type is blurred or foggy vision.
- Acute angle-closure glaucoma involves the rapid buildup of fluid and pressure. Symptoms of this type would include eye pain or severe pressure, blurred vision, tearing, and seeing auras around objects.
How to prevent eye disorders and keep your eyes free of disease.
- Try to keep your blood glucose levels close to normal.
- Watch your blood pressures. Hypertension is not good for the eyes.
- Stop smoking.
- Lower your cholesterol.
- Get an annual eye exam.
