Primary common esotropia

Concomitant strabismus refers to the non-quality lesions in which the optic axis of the two eyes are separated and the inner muscles of the extraocular muscles are innervated. In all directions, regardless of which eye is the gaze eye, the skewness is equal. Non-common strabismus is not the same depending on the fixation eye. If the patient's gaze is increased, the deflection is increased, and the extraocular muscles are weak or paralyzed. Other causes include abnormal innervation of the extraocular muscle restriction (restriction of the eyeball), and AV sign. Primary concomitant esotropia is divided into two major categories: modulating and non-regulating. Adjustable esotropia and sub-refractive and high AC / A.
