Muscle tissue transfer or nerve transfer procedures may also be performed. Some cases may be completely reversed with care. Oculomotor synkinesis affects the movement of the eyes, eyelids, or muscles around the eye when moving a different part of the face. In reality, however, third cranial nerve palsies are often incomplete and result in partial deficits that may be relatively subtle and easily overlooked(Figure 2). The affected eye turns slightly outward and downward when the unaffected eye looks straight ahead, causing double vision. 2012 Jun. When this occurs, the condition is called facial synkinesis.

Ask the patient to alternately occlude each eye to localize the nature of the diplopia. The diagnosis and management of third nerve palsy varies according to the age of the patient, characteristics of the third nerve palsy, and the presence of associated signs and symptoms. [6] Notably, 10 patients (17%) with microvascular ischemic third nerve palsies had pupil involvement, whereas pupil involvement was seen in not all, but only 16 patients (64%) with compressive third nerve palsies.

[QxMD MEDLINE Link]. Epub 2009 Oct 14. A partial third nerve palsy affects, to varying degrees, any of the functions controlled by the third cranial nerve. Sharma R, Gaillard F. Nothnagel Syndrome. Accordingly, damage to the third cranial nerve may cause diplopia, pupil mydriasis, and/or upper eyelid ptosis. Differentiation may be clinical. [6] bear careful consideration, because although compressive lesions had a higher likelihood of pupil involvement, pupil involvement did not exclude microvascular third nerve palsy; moreover, lack thereof did not rule out potentially life-threatening causes of compressive third nerve palsy. If a patient has a dilated pupil and a sudden, severe headache (suggesting ruptured aneurysm) or is increasingly unresponsive (suggesting herniation), neuroimaging (CT or, if available, MRI) is done immediately.

Various forms of facial palsy from damage to the facial nerve may lead to the development of synkinesis. Cleveland Clinic. . Up to 30% of patients with Bells palsy develop synkinesis. The presence of focal visual deficits ipsilateral to the third cranial nerve palsy might suggest an orbital apex syndrome, whereas enlarged blind spots might implicate raised intracranial pressure with papilledema. If CT (or MRI) does not detect blood, a spinal tap Spinal Tap Diagnostic procedures may be needed to confirm a diagnosis suggested by the medical history and neurologic examination. Differential diagnosis for third cranial nerve disorders includes, Midbrain lesions that disrupt the oculomotor fascicle (Claude syndrome, Benedict syndrome), Cavernous sinus disease (giant carotid aneurysm, fistula, or thrombosis), Intraorbital structural lesions (eg, orbital mucormycosis) that restrict ocular motility, Ocular myopathies (eg, due to hyperthyroidism or mitochondrial disorders), Disorders of the neuromuscular junction (eg, due to myasthenia gravis or botulism).

After ice application, improvement of ptosis suggests a disorder of the neuromuscular junction as a possible mimic of a third cranial nerve palsy. In the case of a neuromuscular junction mimicking a third cranial nerve palsy, the diplopia may be truly intermittent. Synkinesis commonly develops weeks to months after nerve paralysis or damage has occurred. Zamproni LN, Ribeiro RT, Cardeal M. Treatment of Recurrent Painful Ophthalmoplegic Neuropathy: A Case Where Pregabalin Was Successfully Employed. American Academy of Ophthalmology. Third cranial nerve palsies can cause variable patterns of diplopia, and manifestations of horizontal and vertical misalignment will reflect to what extent elevation, adduction, and depression of the eye are impaired. Progressive improvement over weeks to months after acute onset symptomatology (diplopia) may implicate an ischemic cranial nerve palsy. [6] Not surprisingly, the annual incidence was higher in older patients (aged greater than 60 years) relative to younger patients (12.5 vs 1.7 per 100 000; difference, 10.8 per 100 000; P < .001).
