Amblyopia (often called “lazy eye”)
Amblyopia develops when one eye, although
it may look healthy, fails to work correctly while the other eye
functions without difficulty. When this happens, the brain receives
two different messages from the eyes. The brain will choose not
to use the vision from the weaker eye, and eventually this eye will
stop functioning if untreated. It is difficult to detect without
a screening test, so make sure your child’s eyes are examined.
What causes amblyopia?
There are two main causes of amblyopia.
- Improper alignment of the eyes causes one eye
to look in one direction and the other eye to look elsewhere.
- One eye has normal vision and another eye does
not. Or one eye might be farsighted and the other nearsighted.
In all cases, the brain receives two different messages and has
to choose one of them.
Treatment for amblyopia is successful when detected
early, usually by the age of four. Either glasses or eye patches
are used for treatment.
Strabismis
Strabismus causes the eyes to point in
different directions. It is a common disorder, and many different
things including heredity, farsightedness, birth defects, and weak
eye muscles can cause it.
If treated early, your child will need only glasses
or an eye patch to correct the problem. However, in severe cases
surgery may be required.
Hyperopia (Farsightedness)
Farsightedness is when one has poor
vision of things that are close. It occurs when the shape of the
eye does not bend light properly. It is usually treated with glasses
Myopia (Nearsightedness)
Nearsightedness is poor distance vision,
and it is usually treated with glasses.
Astigmatism
Astigmatism results in blurred vision
and discomfort. It is caused by a flawed front surface of the eye,
and it is usually treated with glasses.
While a few vision disorders require an operation
to fix them, many problems can be corrected with glasses and vision
therapy. If your doctor recommends surgery for your child, be sure
to get a second opinion before going ahead with the procedure.
Very rarely do children outgrow vision problems.
Instead, the problem will either remain the same or become worse
if left untreated. This can lead to learning and behavioral disorders,
since seeing and interacting with the sights around us is such an
important part of learning and development. Therefore, it is best
to have your child's eyes corrected while young.
