Presentation
The signs and symptoms of neurological disease are elusive by their very nature, presenting a confounding diagnostic challenge. [books.google.com]
If the child presents soon after onset, suppression of the non-dominant eye has usually not been present long enough to produce suppression amblyopia, but a difference in visual acuity may be present later on. [reviewofophthalmology.com]
Some patients may also present with this characteristic ocular motility pattern without overt craniofacial signs ( Figure 1 ). [nature.com]
Methods Physical exam findings from an 8 month old child with bilateral abducens palsies is presented. MRI findings of the brain and orbit are reviewed, including high resolution cranial nerve imaging. [iovs.arvojournals.org]

Treatment of systemic disorders, such as myasthenia gravis, have an excellent prognosis, while inflammation related to multiple sclerosis is likely to improve as well. [encyclopedia.com]
In children, third nerve palsies can be congenital, secondary to serious head trauma, vascular abnormality, tumor, infection, demyelination, inflammation, or even a migraine. [willseye.org]

Conversely, early developmental disturbances of vision often disrupt ocular motor control systems, giving rise to complex disorders such as nystagmus, strabismus, and torticollis. [books.google.com]
Infants noted to have torticollis, or a sustained head tilt, may be referred to a pediatric ophthalmologist to be evaluated for a congenital fourth nerve palsy. Fourth nerve palsies can also be caused by head trauma, infection, or a brain mass. [willseye.org]
Amblyopia of either eye may occur if the patient does not have binocular vision and does not maintain torticollis. Figure 19-1. [entokey.com]

Pathophysiology of strabismus Strabismus often occurs in children who are otherwise completely normal. [patient.info]
Paralytic strabismus poses a significant diagnostic and therapeutic challenge. [1] The prevalence of paralytic strabismus is variable in different studies. [jovr.org]
- Esotropia
Types of strabismus [ 1, 3 ] Esotropia This describes inward-turning squint. Esotropia is sometimes referred to - incorrectly - as lazy eye. (Lazy eye in fact refers to amblyopia, which can be a consequence of childhood esotropia.) [patient.info]
Discussion The term congenital esotropia is often used interchangeably with infantile esotropia, but few cases are actually noted at birth. [webeye.ophth.uiowa.edu]
DIFFERENTIAL DIAGNOSIS OF ESOTROPIA Not all esotropias are VI nerve palsies. Both comitant and non-comitant esotropia have many etiologies. [neuroophthalmology.ca]

Diplopia This is the term used when a patient sees an image in two different places. They are most commonly side by side (horizontal diplopia) but may be one on top of the other (vertical diplopia) or, unusually, oblique to each other. [patient.info]
This may result in horizontal double vision (diplopia) with in turning of the eye and decreased lateral movement. [encyclopedia.com]

Trigeminal neuralgia, a condition characterized by pain coming from the trigeminal nerve, which affects the face — most commonly one side of the jaw or cheek. Trigeminal neuroma, rare tumors that may involve any part of the nerves of the face. [hopkinsmedicine.org]
Involvement of any of the three branches can cause trigeminal neuralgia. [amboss.com]
(see case 13) Radiofrequency rhizolysis for trigeminal neuralgia can cause a transient VI palsy also (29). Cavernous sinus lesions can affect the VI nerve alone or in combination with the other nerves traversing the sinus. [neuroophthalmology.ca]

Workup
Mortality/Morbidity A young patient should have an aggressive workup because of the greater likelihood of a neoplasm causing the palsy. [thehealthscience.com]
Testing: A suggested workup for 6th nerve palsy, adapted from Galetta and Lawton Smith (1989) is as follows: At presentation: General physical, ophthalmologic and neurologic Blood pressure Ascultation for bruits over the eyes and mastoid Cocaine test [dizziness-and-balance.com]
Non-traumatic third nerve palsy cases must undergo a full workups with neuro-imaging. The usual clinical sign of a third nerve palsy is the outward and downward location of the involved eye. This may or may not be accompanied by lid drooping. [wrighteyecare.com]
For any patient who develops signs of aberrant regeneration, workup for a structural lesion is initiated, or repeated if previous workup has been carried out and no lesion found. Nonisolated Cranial Neuropathies MULTIPLE CRANIAL NEUROPATHIES. [medtextfree.wordpress.com]
Workup includes labwork (ESR, CRP, platelets) and potentially temporal artery biopsy in certain cases. Increased intracranial pressure (ICP) can manifest as papilledema, swelling of the optic nerves in the back of the eye. [timroot.com]
Treatment
Thorough coverage for each neurological disease clearly defines age at onset, course of illness, clinical features, and treatment options. Differential diagnosis tables and treatment algorithms expedite clinical decision making. [books.google.com]
It can be used as the sole treatment for sixth nerve palsy, or in addition to a surgical treatment. The operations performed in this study were either transpositions or recess-resect procedures. [healio.com]
A patient's age and clinical findings help a doctor decide the right course of treatment. Treatment: There are no particular treatments which can speed up the recovery of cranial nerve palsy. [lybrate.com]
Two (3.8%) subjects received only medical treatment. 26 (50%) patients received only surgical treatment and both medical and surgical treatments were done in 20 (38.4%) cases. [jovr.org]

Etiology
The aim of this study is to describe demographics and etiologic factors of patients with paralytic strabismus. [austinpublishinggroup.com]
Conversely, slowly progressive onset suggests a compressive etiology. Subacute onset suggests a demyelinating process as a possible etiology. Associated pain suggests a microvascular etiology. [eyewiki.aao.org]
This loss of control of the facial muscles may be temporary or permanent, depending on the etiology, and may affect the eyes, mouth and other areas of the face. [news-medical.net]
Etiology Clinical features Extorsion of the eye : inability to depress and adduct the eyeball simultaneously (the pupil shoots upward during attempted adduction of the eyeball) Diplopia ( double vision ) Mild esotropia Trigeminal nerve lesion (V) Etiology [amboss.com]
An inflammatory etiology, such as Tolosa-Hunt syndrome, is painful and typically responds quickly to steroids. Other etiologic considerations would include aneurysm, bone metastasis, and ophthalmoplegic migraine. [arabmedmag.com]

Epidemiology In 2007, the Moebius Syndrome Foundation estimated that there were at the time a total of approximately 2,000 cases of Moebius Syndrome worldwide [6]. [physio-pedia.com]
Pathophysiology
Sixth nerve palsy causes the eyes to deviate inward (see: Pathophysiology of strabismus ). [en.wikipedia.org]
Pathophysiology Only the ipsilateral lateral rectus that is solely innervated by the involved peripheral sixth cranial nerve is affected; therefore, only deviations in the horizontal plane are produced. [thehealthscience.com]
Pathophysiology of strabismus Strabismus often occurs in children who are otherwise completely normal. [patient.info]
Pathophysiology The fourth cranial nerve nucleus is located in the dorsal mesencephalon. Nerve fibers decussate and exit the brain stem dorsally into the subarachnoid space. [reviewdiseasehandbook.com]
Cadera et al 24 studied pathophysiology of double elevator palsy in two patients with magnetic resonance imaging (MRI) with volume scanning technique. [entokey.com]
Prevention
Prevention Prevention of paralysis depends on prevention of the underlying causes. Risk of stroke can be reduced by controlling high blood pressure and cholesterol levels. [medical-dictionary.thefreedictionary.com]
The hope is that preventing secondary contracture of the medial rectus muscle will increase the chances of recovery without strabismus surgery. [wrighteyecare.com]
Therefore, if close follow-up to resolution of the palsy or paresis is not possible, neuroimaging is recommended.24 Treatment Amblyopia prevention is always key in children younger than 7 to 9 years of age. [guwsmedical.info]
Babies require the use of artificial tears during their waking hours, and eye ointments during sleep, to prevent eye dryness because of inability to close the eyelids completely. [news-medical.net]
