What is Amblyopia? Amblyopia is an eye disorder of the visual system also referred to as the lazy eye. Amblyopia is described as vision deficiency that leads to loss of the eyes’ ability to see details in objects. The affected eye will look physically normal but it does not function normally since the brain is coordinating with the other eye.
This condition develops when the nerve pathway to the brain of one eye does not fully develop during childhood. The affected or abnormal eye tends to send blurred or incorrect images to the brain. When this occurs the brain becomes confused hence it learns how to ignore images from the abnormal eye. The lazy eye may also develop when one eye has a better focus than the other that is one eye might have a lot of astigmatism or it may also be too near-sighted or farsighted.
What is Amblyopia most common cause? Strabismus is the common cause of the lazy eye. It is mainly an imbalance in the positioning of both eyes. It is characterized as an ocular misalignment that leads to one eye either turning inward that is esotropia or turning outwards that is exotropia. This deteriorates the eyes ability to focus on an image which may lead to development of double vision. Other causes of Amblyopia are certain conditions such as cataracts, blood or material at the back of the eye which block entry of light.
Its symptoms and forms of treatment include: Signs and symptoms presented by patients with this vision problem are such as poor vision in one eye, inability to perceive depth, eyes turning in or out and lastly both eyes working together. It can be treated by making the individual’s brain to use the weaker eye. This is achieved via correcting eye problems that cause Amblyopia such as removal of a cataract and then placing a patch on the normal eye and also use of atropine drops.
