Occasional central nystagmus patterns may also present simply with a primary position nystagmus (such as this torsional nystagmus due to a midbrain lesion ). [dizziness-and-balance.com]

• Anorexia

  […] is associated with other ocular conditions (eg, bilateral congenital cataracts) that impair visual acuity and occasionally can herald life-threatening conditions. [1] Some other associated conditions include achromatopsia, Leber congenital amaurosis, anorexia [emedicine.medscape.com]

• Impulsivity

  Oblique muscle surgery was done to correct the oblique plane torticollis which also spontaneously changed the innervational impulses to the neutral zone to the primary position thus correcting the abnormal head posture for distance and for near which [ijo.in]

• Mydriasis

  Fundus viewed ophthalmoscopically after mydriasis did not reveal any rotatory nystagmus. Colour vision was normal. No horizontal or cyclovertical ocular oscilliopsia or ocular torsion could be demonstrated. [ijo.in]

If MRI is not diagnostic, a complete ophthalmologic workup should be pursued. [ncbi.nlm.nih.gov]

Nystagmus that presents after age 6 months is considered late infantile or childhood nystagmus and carries a graver prognosis. The exception is spasmus nutans, with onset in children aged 4 months to 3 years. [emedicine.medscape.com]

Prognosis: Prognosis of all nystagmus and ocular oscillations depends on type of underlying ocular and systemic disease. [omicsonline.org]

Management will depend on the underlying cause of the sensory deficit, as will the prognosis. Neurological nystagmus Neurological disease can present with many forms of nystagmus. Babies tend to present before 2 months of age. [patient.info]

Another benefit of molecular genetic testing in children with a clinical diagnosis of LCA, either before or after ERG, is prognosis for kidney failure. [ncbi.nlm.nih.gov]

Although the exact type of IN waveform is not crucial for the diagnosis of IN itself, knowledge about the different waveforms is helpful in estimating the visual prognosis. [dovepress.com]

Pendular and jerk nystagmus are different manifestations of the same ocular motor instability and simple classification on the basis of waveform is erroneous when used to infer etiology. [jamanetwork.com]

Nystagmus can be physiologic or pathologic according to etiology. [omicsonline.org]

Epidemiology Frequency United States In one US study, the annual incidence of pediatric nystagmus was estimated to be 6.72 per 100,000 persons younger than 19 years, with infantile nystagmus comprising 87% of the study patients. [2] Mortality/Morbidity [emedicine.medscape.com]

We conclude that a congenital‐type nystagmus can emerge or enhance in later life without apparent provocation and is probably associated with a benign pathophysiology. [n.neurology.org]

This work identifies FRMD7 as a key regulator in establishing a neuronal circuit asymmetry, and it suggests the involvement of a specific inhibitory neuron type in the pathophysiology of a neurological disease. [mendeley.com]

Pathophysiology Few patients are noted to have nystagmus onset at birth. The term infantile is probably more accurate than congenital and includes nystagmus that presents within the first 6 months of life. [emedicine.medscape.com]

The pathophysiologic basis for decussation of retinal axons is an area of active research. Pathfinding of retinal axons at the optic chiasm is incompletely understood at this time. [ajnr.org]

The exact pathophysiologic mechanism of true congenital nystagmus is not known. [ijo.in]

Prevention There are no known ways to prevent nystagmus. Treatment Treatment for nystagmus depends on the kind of nystagmus present. There is no cure for nystagmus. [sauganasheye.com]
