It is present physiologically in everyone to a minor degree under certain conditions but it is often pathologic when exaggerated movements are present during normal visual activities. [disorders.eyes.arizona.edu]

The signs and symptoms of neurological disease are elusive by their very nature, presenting a confounding diagnostic challenge. [books.google.com]

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]

Inheritance - congenital achromatopsia is transmitted in an autosomal-recessive trait Presentation - patients present in early childhood with nystagmus, abnormal visual behaviour or photophobia. Acuity is less than 20/200. [patient.info]

• Nystagmus

  If the nystagmus is horizontal, the eye movement is usually "to-and-fro". [disorders.eyes.arizona.edu]

  See Caloric nystagmus, Irritative nystagmus, Paralytic nystagmus, Recovery nystagmus, Opticokinetic nystagmus, Seesaw nystagmus. nys·tag·mus ( nis-tag'mŭs ) Rhythmic oscillation of the eyeballs, either pendular or jerky. [medical-dictionary.thefreedictionary.com]

  Although the nystagmus frequency was also gaze-angle dependent, it was equal in both eyes. In the null region both nystagmus amplitude and frequency were minimal and equal for the two eyes. [journals.lww.com]

  Dissociation is common with pendular nystagmus. Acquired pendular nystagmus is dysconjugate in both size and direction in half of cases (Video “acquired pendular nystagmus” ). [neuroophthalmology.ca]

  Pendular nystagmus) Characterised by slow pendular oscillations generally the wave form is very variable. Established pendular nystagmus (by about 6 months in congenital visual deprivation) has a poor visual prognosis. Rarely ever better than 6/36. [slideshare.net]

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]

Treatment Treatment Options: Congenital nystagmus cannot be cured. However, several treatments may be beneficial. Glasses and contact lenses, and, occasionally, extraocular muscle surgery may be helpful. [disorders.eyes.arizona.edu]

What treatments are available for Nystagmus? Unfortunately, there are not many good treatments for nystagmus. For some specific types, medicines can help and surgery can be used to improve certain features, but for most, little treatment exists. [rnib.org.uk]

Current treatments, such as prism glasses, acupuncture, electronic nerve stimulation, contact lenses, various drug treatments, and others have had limited success. [clinicaltrials.gov]

At present, there is no treatment for this condition. [afb.org]

Prognosis - there is no progression. [patient.info]

Diagnosis and Prognosis: Pediatricians and ophthalmologists are likely to make this diagnosis. It is important that complete physical and neurological examinations are done to rule out other conditions with which nystagmus is associated. [disorders.eyes.arizona.edu]
