Within the cavernous sinus the CN III runs in the lateral opposite tilt (BOOT). As the name suggests, the oculomotor nerve supplies the majority of the muscles controlling eye movements (four of the six extraocular muscles, excluding only the lateral rectus and superior oblique ). Other common causes include[2]: Also, all pediatric patients with strabismus should be checked for uncorrected refractive error after administering cycloplegics.[5]. innervates the If the pupil is affected and patients are increasingly unresponsive, neuroimaging is done as soon as possible to check for transtentorial herniation. differentiates a surgical from a medical lesion.

There are 12 pairs of cranial nerves that control most head and neck functions. If the pupil is affected, consider aneurysms and transtentorial herniation; if the pupil is spared, consider ischemia of the nerve (usually secondary to diabetes or hypertension). failure of [11]CT angiography should be urgently performed if clinical examination suggests an aneurysm.

The main trunk of CN III is supplied by the vasa nervorum. After the paralytic strabismus is treated, the ptosis can be corrected. Third Cranial Nerve Palsy. The etiology and presentation of acquired third-nerve lesions at various levels are different[2]: All acquired third-nerve palsycases should be investigated thoroughly to exclude any space-occupying lesion. These fibres are located superficially in the superomedial part Parks-Bielschowsky 3-step test is useful in the diagnosis.

[11]This shows the nerve as a dark linear image in contrast to the high intensity of the signal from the surrounding cerebrospinal fluid (CSF). The third cranial nerve is also known as oculomotor nerve and has two major components, the outer parasympathetic fibers that supply the ciliary muscles and the sphincter pupillae tumour causing the nerve trunk to be stretched and tethered, vasculitis associated with collagen vascular In addition, pupillary dilatation can cause anisocoria (greater in the light), . A cranial nerve palsy can occur due to a variety of causes. The third cranial nerve controls specific eye movements, certain pupil functions and upper eyelid function. Keane JR.

Unilateral CN IV palsy is characterised by less Left hypertropia may be caused by South Africa, Correspondence causes include hypertension and diabetes. Edinburgh: Butterworth On the other hand, medical lesion such as diabetes mellitus or hypertension microangiopathy will affect the vasa vasorum and thus spare the pupillary fibers. The nerve then divides into a superior and inferior division and enters the orbit through the superior orbital fissure. Involvement of CN III will produce a symptom Imaging of Cranial Nerves III, IV, VI in Congenital Cranial Dysinnervation Disorders. Cases of Stroke Presenting With an Isolated Third Nerve Palsy Magnetic Resonance Imaging of Third Cranial Nerve Palsy and - LWW [7]Pupil involvement was seen in 43% of patients on presentation, however, 86% of patients presented with ptosis on the first visit. Overall, the common etiologies in children and adolescents include the following, in decreasing order: neoplasm (tumor), idiopathic, inflammation, and non-aneurysmal vascular problem. People have double vision when they look in a certain direction, the eyelid droops, and the pupil may be widened (dilated). These functions include swallowing, facial sensations, eye movements and other facial movements. While there are several causes of third cranial nerve palsy, the most common have been identified as hypertension and diabetes mellitus [1,2]. leaves the brainstem on the dorsal An interesting point to note is that before the 3 nerve reaches the orbit, the fibers innervating the pupillary muscles (pupillomotor fibers) are located superficially in the nerve trunk. Third cranial nerve palsy in children - PubMed Sometimes the pupil is also abnormally enlarged on that side. A palsy of the 3rd cranial nerve can impair eye movements, the response of pupils to light, or both. This is all the more true for people above the age of 60. An overview of the third, fourth and sixth cranial nerve palsies . Even excluding third cranial nerve palsies from this cohort (as the majority of third cranial nerve palsy patients will undergo neuroimaging regardless of the presence of vasculopathic risk factors), the incidence of other causes for fourth and sixth cranial nerve palsies was 13.5% (five of 37).
