Amblyopia Lazy Eye

Amblyopia or lazy eye is the vision of one of the eyes is reducing because the eye and the brains are not coordinating (working together) properly.

Amblyopia Lazy Eye

The eye looks normal, but it is not being use normally because the brain is favoring the other eye. Simply, amblyopia is a dysfunction of the brain which blocks vision from one eye because it cannot use the vision of two eyes together.

It means that one eye has not developed normally and always has blurred vision; even with the best choice of glasses or a contact, which prescribed.

Lazy eye amblyopia sign and symptoms

Symptoms may include noticeably favoring one eye or a tendency to bump into objects on one side. Symptoms are not always obvious.

Lazy eye amblyopia causes

Children with normal vision start learning to use both eyes together in their first few months from birth. Their brain develops the ability to make the pictures coming in from both left and right eyes and merge these two pictures into an actual single image, known as normal two-eyed vision.

Anything that interferes with clear vision in either eye during the critical period (birth to six years of age) can cause amblyopia. The most common causes of amblyopia are:

  • Constant strabismus (constant turn of one eye) may develop amblyopia called Strabismus Amblyopia,
  • One eye is more nearsighted, farsighted, or astigmatic than the other called Refractive Amblyopia
  • Blockage of an eye due to cataract, trauma, lid droop, etc

Amblyopia is a neurologically active process. In other words, the loss of vision takes place in the brain. If one eye sees clearly and the other sees a blur, the brain can inhibit (block, ignore, suppress) the eye with the blur. The brain can also suppress one eye to avoid double vision. The inhibition process (suppression) can result in a permanent decrease in the vision in the blurry eye that cannot correct with glasses, lenses, or lasik surgery.
