Amblyopia

Apr 30th 2020 at 11:43 AM

Amblyopia is a chronic vision condition in which an individual does not reach regular visual acuity, even with recommended eyeglasses or contact lenses. Amblyopia is also known as lazy eye starts during infancy and early childhood. In most instances, it involves just one eye. Genetics often play a part. Among families, amblyopia tends to run. It is also more common among prematurely born babies or those with developmental delays.

Amblyopia happens when one or both eyes during early childhood fail to develop normal vision. In every eye, babies aren't born with 20/20 vision. ... Then, vision will diminish and the affected eye will become amblyopic.

The method of inhibition (suppression) can result in a permanent loss in the vision in that eye that cannot be corrected with glasses, lenses or Lasik surgery. Normally, Healthcare Consultant in India can help in early treatment of amblyopia or lazy eye is simple, using eyeglasses, drops, vision therapy, and/or eye patching.

Common Causes of Lazy Eye: Strabismus, Anismetropia, Blockage of Eye

The most common causes of amblyopia are:

· Constant strabismus (constant turn of one eye in any direction, but an inward turn or crossed eyes is much more common),

· Anisometropia (differences in vision and/or prescription between the two eyes) which leads to anismetropic amblyopia or refractive amblyopia, and/or

· Physical blockage of an eye due to cataract, trauma, lid droop (ptosis), blocked tear duct, etc.

· Less common causes of lazy eye are reported to be congenital disorders and vitamin A deficiency.

Common Causes of Lazy Eye: "Suppression"

Frequent suppression (blocking out or ignoring) of one eye's image by the brain can lead to the development of a lazy eye condition. The following visual conditions can cause suppression:

· Strabismus: the two eyes do not aim at the same place, so the brain will suppress -- block, ignore, inhibit -- one eye to avoid confusion and/or double vision (diplopia). This type of lazy eye condition is easier to detect because there is an eye turn that is visible to the outside observer.

· Anismetropic Amblyopia: the two eyes have significant differences in eyesight, visual perception, or prescription (e.g., differences in astigmatism, nearsightedness, farsightedness, etc.). In this case, the brain perceives two mismatching images and opts to throw one out (suppress) to avoid the rivalry between the two eyes or double vision (diplopia). This type of lazy eye often goes undetected and untreated because there can be no visible eye misalignment or the eye turn is occasional.

· Refractive Amblyopia (a type of anismetropic amblyopia): one eye sees clearly and the other eye sees blurry, so the brain suppresses the eye with the blur.

· Convergence Insufficiency: this common near vision disorder can cause suppression in one eye, but because the suppression is occasional (intermittent) and/or might alternate between one eye and then, the other, it rarely leads to a true lazy eye condition (Amblyopia).

The most common causes of amblyopia are constant strabismus (constant turn of one eye in any direction, but an inward turn or crossed eyes are much more common), Anisometropia (differences in vision and/or prescription between the two eyes) which leads to anismetropic amblyopia or refractive amblyopia, and/or physical blockage of an eye due to cataract, trauma, lid droop (ptosis), blocked tear duct, etc. Other less common causes are reported to be congenital disorders and vitamin A deficiency.
