Ask if your condition can be treated in other ways. However, in patients with large deviations, the thickness of the prism required may reduce vision so much that binocularity is not achievable. In this situation, surgical intervention is indicated to establish or broaden the field of single binocular vision, with the surgical approach highly dependent on the presence of residual lateral rectus function.A complete sixth nerve palsy is characterized by a floating saccade toward central gaze from the resting esotropic, adducted eye position. Joe', A Conversation Between ACSH and Great.com. The disorder prevents some of the muscles that control eye movement from working properly.

[11] The Cochrane review authors judged this to be low-certainty evidence; the study was not masked and the estimate of effect was imprecise. Limitations of eye movements are confined to abduction of the affected eye (or abduction of both eyes if bilateral) and the size of the resulting convergent squint or esotropia is always larger on distance fixation - where the lateral recti are more active - than on near fixation - where the medial recti are dominant. Some people may have permanent vision changes. Diplopia is also increased on looking to the affected side and is partly caused by overaction of the medial rectus on the unaffected side as it tries to provide the extra innervation to the affected lateral rectus.

If, after three months, there are no signs of clinical improvement for isolated sixth nerve palsies, it is appropriate to initiate a neurologic workup to look for the nonvasculopathic etiologies (Table 1). Sixth cranial nerve palsy is weakness of the nerve that innervates the lateral rectus muscle. The lateral rectus muscle rotates the eye away from the nose and when the lateral rectus muscle is weak, the eye crosses inward toward the nose ( esotropia ). The esotropia is larger when looking at a distant target and looking to same side as the affected lateral rectus muscle. The eyes may also be out of alignmenta symptom called strabismus.
