Lesions anywhere in the abducens nucleus, cranial nerve VI neurons, or interneurons can affect eye movement towards the side of the lesion. Lesions on both sides of the abducens nucleus can cause a total loss of horizontal eye movement. [6] One other type of gaze palsy is a horizontal saccadic palsy.
Internuclear ophthalmoplegia (INO) is a disorder of conjugate lateral gaze in which the affected eye shows impairment of adduction. When an attempt is made to gaze contralaterally (relative to the affected eye), the affected eye adducts minimally, if at all. The contralateral eye abducts, however with nystagmus.
Hemianopsia, or hemianopia, is a visual field loss on the left or right side of the vertical midline. It can affect one eye but usually affects both eyes. Homonymous hemianopsia (or homonymous hemianopia) is hemianopic visual field loss on the same side of both eyes. Homonymous hemianopsia occurs because the right half of the brain has visual ...
Limitation of abduction of the right eye. This individual tries to look to his right, but the right eye fails to turn to the side. The nerve dysfunction induces esotropia, a convergent squint on distance fixation. On near fixation the affected individual may have only a latent deviation and be able to maintain binocularity or have an esotropia ...
Dysmetria (English: wrong length) is a lack of coordination of movement typified by the undershoot or overshoot of intended position with the hand, arm, leg, or eye. It is a type of ataxia . It can also include an inability to judge distance or scale.
Symptoms are usually limited to one side of the head, and in most cases the individual affected will experience intense, sharp pain and paralysis of muscles around the eye. [3] Symptoms may subside without medical intervention, yet recur without a noticeable pattern.

This acts to 'weaken' its action and allow the eye to move back into a more neutral alignment. [6] In all cases of congenital fourth nerve palsy, it is important to see an experienced strabismologist about management/treatment options. A strabismologist is an ophthalmologist (eye doctor) specialising in eye movement disorders.
