Exotropia is a very common type of strabismus that manifests itself as a lateral deviation of the eye. The causes of this condition are divided into congenital and acquired causes. Congenital causes are usually due to poorly functioning extraocular muscles, so this condition is more common in children. Acquired exotropia is caused by very poor vision in one eye or the presence of nerve palsy, ocular trauma, orbital disease, etc., which leads to abnormal eye position. Treatment for exotropia depends on the specific type. For congenital exotropia, surgical correction is considered necessary. For acquired exotropia, treatment for the specific cause is needed in the early stages, and surgical correction is considered when conservative treatment is ineffective.
