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]

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

It is accepted as neurologically benign, however, in cases with associated systemic and neurological problems and in cases that is diagnosed after 6 months neuroradiological evaluation and systemic workup are required. [omicsonline.org]

Pedigree: Autosomal dominant Autosomal recessive X-linked recessive, carrier mother X-linked recessive, father affected Treatment Treatment Options: Congenital nystagmus cannot be cured. However, several treatments may be beneficial. [disorders.eyes.arizona.edu]

In this Children's Channel video, Richard Hertle, MD, FAAO, FACS, FAAP, director of pediatric ophthalmology at Akron Children's Hospital, discusses the signs and symptoms of congenital nystagmus, as well as the comprehensive care required for proper treatment [akronchildrens.org]

Prognosis Nystagmus intensity (frequency x amplitude) often improves spontaneously with increasing age but depends on etiology. [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]

Prognosis Nystagmus intensity (frequency x amplitude) often improves spontaneously with increasing age but depends on etiology. [emedicine.medscape.com]

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

It can have many etiologies—structural and functional brain abnormalities, medication side-effects, cancer, genetic and metabolic disorders and many more. [aapos.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]

Differential diagnosis Nystagmus should be distinguished from inappropriate saccades that prevent steady fixation (eg, ocular flutter). [patient.info]
