Amblyopia (Lazy Eye)

What is Amblyopia?

Lazy eye, technically called Amblyopia, means that one or both eyes have blurred vision even with the correct glasses. Amblyopia is a disorder of the brain which blocks vision from one eye because both eyes cannot be used together. Because the brain suppresses the vision in one eye early in life, normal sharpness of vision does not have a chance to develop.

What causes Amblyopia?

Amblyopia can develop when any of the following conditions occur:

Children under 9 years of age whose vision is still developing are at the highest risk for Amblyopia. Generally, the younger the child is, greater is the risk.

How is it treated?

Amblyopia can often be reversed if it is detected and treated early. Cooperation of the patient and parents is important to achieve good results.
If left untreated or if not treated properly, the reduced vision or Amblyopia becomes permanent and vision cannot be improved by any means.
The most effective way of treatment is to make the child use the lazy eye. Covering or patching the good eye to force the use of the amblyopic eye may be necessary to ensure equal and normal vision. This can be achieved by:

 Occlusion is done from a few hours to a few days, depending upon the age of patient and the type and severity of Amblyopia.  Those patients who are patching their eyes need periodic follow-up, which is scheduled with a Pediatric Ophthalmologist. Duration of treatment may extend from months to years. The Pediatric Ophthalmologist can make a determination for how long the occlusion should be continued.

Importance of Treatment

If Amblyopia is left untreated, a child's vision will never fully develop correctly in that eye. Vision impairment becomes permanent because as the child’s brain matures, it will "ignore" the image coming from the poorly seeing eye. Because Amblyopia can result in permanent vision loss in one eye, it is important to have a child with Amblyopia regularly tested by a Pediatric Ophthalmologist.
