If a child’s presentation does not precisely fulfill the criteria for congenital motor nystagmus, neuroradiologic testing is necessary. Spasmus nutans. Spasmus nutans is acquired, typically presenting between the ages of 3 and 15 months. [aao.org]

Latent Nystagmus Horizontal jerk nystagmus presents when the light stimulus is reduced to either eye (eg by occluding). In latent, no observable movement is present on uncovering and full BSV is restored. [slideshare.net]

Recommended lab workup includes TORCH titers, VDRL, serum calcium and phosphorus levels and urine for reducing substance. Additional systemic workup should be done in coordination with the pediatrician. [eyewiki.aao.org]

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]

Prognosis The course and prognosis of pediatric cataracts is highly variable. The likelihood and rate of progression is very difficult to predict. [eyewiki.aao.org]

Affected individuals should talk to their physician and medical team about their specific case, associated symptoms and overall prognosis. [rarediseases.org]

Prognosis Congenital nystagmus is usually a benign condition. It is not curable, but its symptoms can be diminished with spectacles or contact lenses. [healthofchildren.com]

Prognosis is excellent since spasmus nutans usually resolves by the age of 3 to 4 years. See-saw nystagmus. This form is clinically unique, with both vertical and torsional components. [aao.org]

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

Abstract Background: Most patients with pure nonprogressive congenital cerebellar ataxia have a sporadic form of unknown heredity and etiology. [neurology.org]

Etiology The causes of infantile cataracts have been the source of much speculation and research. Making a distinction between unilateral and bilateral cataracts may be useful when considering etiology. [eyewiki.aao.org]

Discussion The heterogeneity of congenital nystagmus has been well established on the basis of etiology, hereditary pattern, and waveforms. [healio.com]

Epidemiology The exact incidence and prevalence of nystagmus is not known but it is thought to occur in about 1 in 1,000 people. [patient.info]

Fanconi analyzed its epidemiology and found that the virus was not transmitted by droplet infection, as previously assumed and his understanding of pathophysiologic connections culminated in his prediction that Down syndrome was due to a chromosomal abnormality [wikivisually.com]

While this distinction may be conceptually correct, it does not always reflect the underlying pathophysiology. [aao.org]

An IOL can prevent the formation of a Sommering’s ring, but it is also easier for the lens epithelial cells to migrate to the center of the pupil. [eyewiki.aao.org]

Prevention In general nystagmus cannot be prevented. [healthofchildren.com]

Prevention Because some cases of Noonan syndrome occur spontaneously, there's no known way to prevent it. However, if you have a family history of this syndrome, talk to your doctor about the benefits of genetic counseling before you have children. [mayoclinic.org]
