Your brain and eyes work together to provide your sense of sight. When they fail to coordinate properly, you may develop vision disorders, such as amblyopia. This refers to the lack or loss of central vision development in one eye that cannot be corrected by regular lenses.
Your vision correction experts at Myopia Institute discuss this problem further.
What Causes Amblyopia?
Amblyopia has three classifications based on the root cause: strabismic, refractive and deprivation. Strabismic amblyopia, the most common form, happens when your brain tries to ignore visual input from your misaligned eye. As a result, this affected eye gradually loses its function, which is why it’s also referred to as “lazy eye.”
Refractive amblyopia, on the other hand, occurs when your eyes have unequal refractive errors. One eye may have severe myopia, for example, while the other does not. Your brain relies on the better eye and tunes out the other one. Lastly, deprivation amblyopia may develop when something obstructs light from entering your eyes. Performing an eye exam can establish determine which type you have.
What Are the Symptoms?
Crossed eyes or some other form of eye misalignment may be a sign of strabismic amblyopia. Having a hard time seeing clearly when covering one of your eyes may indicate refractive amblyopia. Frequent squinting or head tilting may be a compensatory mechanism for this vision problem as well.
How Is It Managed?
Corrective eyeglasses or contact lenses can help manage refractive amblyopia. We may also recommend using a patch on your good eye for a certain period. Doing so forces your brain to pay attention to the image signals sent by the amblyopic eye. Applying atropine eye drops to the unaffected eye causes it to become blurry. As a result, your brain will rely on the weaker eye for visual input.
If you have strabismic amblyopia, we may suggest performing surgeries to straighten your eyes. Patching can also help. We may include vision therapy as well to improve the working relationship between your eyes and brain. Deprivation amblyopia may be managed by removing obstructions in your eyes as soon as possible.
