Esotropia, commonly called crossed eyes, is the visual condition in which a person uses only one eye to look at an object while the other eye turns inward. Esotropia is one of several types of Strabismus, which is the condition of eye turns or deviating eyes. Esotropia is the most common type of Strabismus, occurring in approximately 1-2% of the population. This condition usually does not involve faulty or damaged eye muscles. Eye coordination may not be developed enough to provide normal control of the person's binocular vision.
Our two eyes work together as a binocular system. When our two eyes work together well, we can easily and efficiently measure the location of objects in relation to ourselves. Binocular vision makes it easier for us to ride a bicycle, drive a car, or direct many other daily activities. An eye that wanders is much more than just an appearance problem. For example, reading demands accurate binocular vision. When a person's eyes do not aim at the same place accurately and simultaneously, he or she will have much more difficulty with large amounts of reading, writing, and other close work.
Treatments involve the use of lenses and vision therapy. Patching one eye may also make the person more aware of the eye that is misused. COVD doctors will thoroughly evaluate this condition and provide treatment options.
