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]

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]

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]

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]
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]

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]
PreventionPrevention 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]
Occlusion using Bangerter filter or pirate patch can eliminate diplopia and confusion, prevent amblyopia or suppression in younger patients, and decrease the possibility of ipsilateral medial rectus contracture.[eyewiki.aao.org]
