Deviated torsion of eye movement

Introduction Eye movement deflection: The imbalance of the muscle strength of the eye wall caused by various reasons produces the deflection of the eye movement.

Cause

The cause of the deflection of the eye movement:

The eyes of the person can rotate freely up and down together, relying on the six muscles that pull each eye wall to closely cooperate, coordinate and restrict each other. If one of the muscles is too strong or too weak to balance with other muscles, it will cause the eye movement to skew or even reverse.

Examination and diagnosis of eye movement deflection:

It can be seen in ependymoma, which affects the nucleus of V, VI, VII, and VIII in the upper part of the fourth ventricle. The growth along the midline affects the medial longitudinal bundle, and the eye can be paralyzed to the affected side, and eye movement can also occur. Skewed torsion.

Differential diagnosis

Eye movements are skewed and confusing symptoms:

1. Etiology identification: It is mainly based on the diagnostic criteria for different intracranial or extracranial diseases that can cause damage to the motor or nerve nucleus of the eyeball or extraocular muscle paralysis.

2. The location diagnosis and differentiation of the eye movement nerve or nerve nucleus injury is identified according to the different characteristics of the ocular dyskinesia and the combined symptoms.
