Amblyopia (Lazy Eye)
“Lazy eye” affects about four million people in the United States. It occurs when, for one of several reasons, one eye is used less than the other. If one eye is crossed or turns out, the individual sees double, so he or she learns to “shut off” or ignore that eye. If the two eyes are very different, one nearsighted and the other farsighted, the same thing can occur. After a while, vision in the unused eye is reduced.

If we suspect an ocular condition or disease,
we will immediately schedule or perform
diagnostic tests to determined our next steps.

For many years it was thought that amblyopia, or “lazy eye” – when one eye sees poorly and cannot be helped with corrective lenses – was a permanent condition unless it was detected and treated before the age of six. Many optometrists no longer accept this, believing that even adults can improve their sight - if not completely correct their lazy eye – through therapy.

The American Optometric Association agrees that current research proves the old theory wrong. The success rate does drop off as one gets older, but the cut-off at age six is arbitrary. Age should not be a barrier, though the longer the condition has existed the more difficult it becomes to treat.

Treatment varies depending on the extent of the condition, the patients’ age and the optometrist. Small children often have their stronger eye patched for several hours a day. This stimulates the use of the weak eye while they perform exercises such as coloring, cutting things out and tracing.

Vision therapy – usually several hours a week, in the doctor’s office and at home – will often correct the underlying reason for the lazy eye. Very small children can improve in a month or two; older children may take several months to a year to respond.

With adults, treatment is basically the same, but it takes longer. Adults may not wear a patch at all if vision is very poor, or only for an hour or two at home while doing fine tasks such as coloring in the 0’s of a newspaper. Patients do exercises designed to improve focusing, tracking and spatial judgment.

Many times after treatment, 50 percent of the older children and adults see as well or almost as well with their lazy eye as with their normal eye, and four out of five of the rest at least show improvement. Results are permanent when both the amblyopia and the underlying problem are corrected. When the latter can’t be treated, patients should continue the exercises on a less-frequent basis and visit their optometrist periodically so that the eye does not weaken again.

Symptoms include a wandering eye, eyes that may not appear to work together, or poor depth perception. Both eyes may be affected.

Amblyopia typically occurs in early childhood. When nerve pathways between the brain and an eye aren't properly stimulated, the brain favors the other eye. In most cases, only one eye is affected. However, in some cases amblyopia can occur in both eyes.

Treatment includes eye patches, drops, glasses or contact lenses, and sometimes surgery.

Symptoms of amblyopia can be hard to notice. Kids with amblyopia may have poor depth perception — they have trouble telling how near or far something is.

Parents may also notice signs that their child is struggling to see clearly, like:
• Squinting
• Shutting 1 eye
• Tilting their head

In many cases, parents don’t know their child has amblyopia until a doctor diagnoses it during an eye exam. That’s why it’s important for all kids to get a vision screening at least once between ages 3 and 5.

We all want to to protect our eyesight and that is why it is important to have annual vision tests. This allows us to detect changes in the front of your eye so that alterations can be made to your eyeglass or contact lens prescription. We also need to inspect the retina to check if it is healthy, damaged, or showing signs of disease.
