Strabismus is a condition in which the eyes are not properly aligned with each other. It typically involves a lack of coordination between the extraocular muscles that prevents bringing the gaze of each eye to the same point in space and preventing proper binocular vision, which may adversely affect depth perception. Strabismus can be either a disorder of the brain coordinating the eyes or a disorder of one or more muscles, as in any process that causes a dysfunction of the usual direction and power of the muscle or muscles.
The two eyes normally should be in a definite visual axis. A manifest deviation of the visual axis of either eye is known as squint or strabismus. So one eye is deviating or squinting, the other eye takes up the visual function mainly. So it becomes a dominate eye. Most of the time, the deviating eye slowly becomes impaired functionally. Later it almost becomes blind. This hard fact will not be known to the squinting person unless he closes the good eye and tests for the other eye vision.
Strabismus is a misalignment of the eyes where one or both eye turns in toward the nose (estropia) or one eye turns away from the nose (exotropia). It is also possible for one or both eyes to turn down or up in different directions. The disorder can occur suddenly or gradually. Botox injections can help lengthen one muscle and shorten the other in order to properly align the eyes. Typically, the results last for up to three months and can be repeated as often as necessary so long as the patient continues to respond to treatment.
