Therefore, abnormal eye alignment in childhood blocks normal binocular vision development (as the brain learns to rely on only one image from the fixing eye).Īlthough the avoidance of double vision is beneficial in some regard, this adaptation by the developing brain is also detrimental because the ignored eye loses the ability to see perfect “20/20” vision – a condition called amblyopia. Eye misalignment typically results in double vision in adults, but the developing brain in a child deals with the double vision by suppressing one of the images. On the other hand, if the eyes do not switch fixation (one eye is constantly the fixating eye and the other eye is constantly the misaligned eye), then the fixating eye is favored and almost always has better vision.Įsotropia and exotropia are common conditions among children. This alternation of deviating eye is often a good sign suggesting that the vision in each eye is equal. Often times the eye that is fixing on objects switches that is, the misaligned eye will fixate and the previously fixing eye will become the misaligned eye. When the eyes are misaligned, typically one eye will fixate on objects of interest while the other eye turns in (esotropia), out (exotropia), down (hypotropia), or up (hypertropia). This misalignment may be constant or intermittent. Strabismus is a visual disorder in which the eyes are misaligned and point in different directions.
