What is Strabismus? This is a misalignment of the eyes. While one eye works properly, there is a deviation in the other eye(unilateral strabismus) and if the eyes takes turn alternately to deviate, it means there is alternating strabismus. When the eye turns In - Esotropia Out-Exotropia Up- Hypertropia Down- Hypotropia Primary visible Signs are eye turn. If the deviation is too small then it can be picked up by either a cover/uncover test or corneal light reflex(hirchberg test). In Large deviations, there is pretty much no symptoms. Because there is a noticeable misalignement, the brain does bot bother to correct the eye to match the other eye. Therefore if left untreated, it causes an amblyopia(lazy eye) in the affected eye. In other cases, patients may experience headaches, eye strain, decreased visual performance. Most child are born with deviations in eye because of the process of vision production. As they grow older, and the vision is restored, there should not be any deviation. However, most cases of strabismus does not disappear as the child grows up. That is why a child needs to have a routine eye test. Causes of Strabismus.
