Amblyopia

  1. 1.  Amblyopia is when the nerve pathway from one eye to the brain doesn’t develop during childhood. This occurs because the abnormal eye sends a blurred image or the wrong image to the brain. Amblyopia can affect the first decade of childhood (1-10 yrs old). It is the most common vision problem in children.
  2. 2.  Amblyopia usually starts when one eye has much better focus than the other eye. › For example: one eye might be very nearsighted or have a lot of astigmatism, while the other does not. When the brain is confronted with both a blurry image and a clear image, it will begin to ignore the blurry image. If this goes on for months or years, the vision in the eye that sees the blurry image will deteriorate.
  3. 3.  Another cause of amblyopia is “strabismus”. › Strabismus is an ocular misalignment, meaning that one eye turns inward or outward. › This prevents the eyes from focusing together on an image and can cause double vision. › As a respond, the brain generally chooses to ignore the image from the abnormal eye, causing the vision in that eye to deteriorate. › Because one of the eyes is misaligned, some people refer to this as a "lazy eye."
  4. 4.  Eyes that don’t appear to work together Inability to judge depth correctly Poor vision in one eye Easily diagnosed with a complete examination of the eyes Eyes turn in or out
  5. 5.  Correcting the optical deficit, (wearing glasses), forcing use of the eye You can patch the good eye or apply topical atropine in the eye with better vision Full recovery is near impossible in anyone over eight However, treatment in Ages 9-adult is possible through applied perceptual learning
