What is Amblyopia?

Amblyopia is the loss of vision caused when a clear image of the world is not available on the retina during key periods of development. In newborns and young children, the visual cortex of the brain develops dramatically. It keeps growing during the first ten years of life

 Symptoms of amblyopia?

The majority of amblyopia cases are identified during routine eye exams without any symptoms being present. Reduced visual acuity is a sign of amblyopia; however, this is usually not seen unless the child gets her eyesight examined.

  • Frequently rubs, squints, or shuts one eye
  • Tilts the head to the side
  • Challenges with reading
  • Math challenges
  • The poor athletic performance or a history of accidents
  • Decreased fine motor abilities

Amblyopia causes

Amblyopia can develop from other eye and vision problems, such as:

  • Strabismus: strabismus occurs when the eyes have different directions. The brain is confused after receiving two different images. The image from the eye that is not facing straight ahead may be ignored by the brain in order to prevent seeing double. During a child’s visual development, this continual disregard of the image from one eye might lead to poor eyesight. Your child’s vision will remain poor if it is not treated.
  • Refractive errors–   Refractive error, nearsightedness, or farsightedness are all examples of refractive errors. A youngster may have an eye with a worse refractive error than the other. The “turning off” of that eye could prevent appropriate visual development. Since the child’s eyesight appears to be fine when both eyes are being used, it can often be challenging to notice this.
  • Vision blockage – Amblyopia is caused by anything that prevents images from being focused on the retina and prevents the eye from delivering signals for vision. This is known as derivational amblyopia and is a particularly potent inducer of amblyopia. Some children are born with cataracts, which are conditions where the typically clear lens of the eye becomes hazy. Another cause of this is a sagging eyelid (ptosis), which prevents light from reaching the eye.

How to prevent amblyopia?

Early diagnosis and treatment of strabismus, astigmatism, cataracts and other visual issues can stop amblyopia in its tracks.

Amblyopia and the accompanying vision issues that may lead to it cannot be avoided. But you can stop it from deteriorating or posing long-term issues. Getting routine eye exams is the greatest method to stop amblyopia from causing vision loss. By the age of 6 months and again by the age of 3 years, make sure your child has had a comprehensive eye examination.
