Occult strabismus refers to strabismus that can be controlled by the fusion reflex in the orthoptic position and maintain binocular monovision, and is undetectable without examination. Clinically, it is common to eliminate the fusion reflex artificially in order to determine the presence and nature of occult strabismus in the examined person.
Hidden strabismus can be categorized into esotropia and exotropia according to the de-covering eye method, where rapid movement from the outside to the inside is called exotropia, and movement from the inside to the outside is called endotropia. Mild occult strabismus is asymptomatic because of good binocular monovision, while more severe cases require glasses, with a bottom-out pressure-applied trephine lens for internal strabismus and a bottom-inward trephine lens for external strabismus.
Asymptomatic occult strabismus does not require treatment. However, if the patient with occult strabismus develops visual fatigue, the refractive error should be corrected in a timely manner, exercises should be strengthened, and mental stress and over-exertion should be eliminated, and appropriate treatment should be given if necessary.
The specific situation and the need for treatment is recommended to the hospital.
