In this paper, the authors present a case study of a patient whose nystagmus has a strong and exclusive male hereditary component. Genetic argumentation is presented in support of this conclusion. [ncbi.nlm.nih.gov]

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]

• Lymphadenopathy

  Fever, anorexia, nausea and vomiting, lymphadenopathy and skin hyperpigmentation may occur. There can be pleural effusions and lobar infiltrates (1257). [neuroophthalmology.ca]

• Cheyne-Stokes Respiration

  Cheyne's nystagmus a peculiar rhythmical eye movement resembling Cheyne-Stokes respiration in rhythm. congenital nystagmus may be a primary functional defect or secondary to lesions in the visual pathways, sometimes associated with albinism. [medical-dictionary.thefreedictionary.com]

• Flushing

  Cold or warm water flushed into the ear canal will generate motion signals from the inner ear. The eyes will respond to this signal with nystagmus if the pathways are intact. Causes and symptoms There are many causes of nystagmus. [medical-dictionary.thefreedictionary.com]

• Nystagmus

  Our present understanding of the genetics of hereditary nystagmus is somewhat limited. Few published medical sources have documented the existence of true cases of sex-linked hereditary nystagmus. [ncbi.nlm.nih.gov]

  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]

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

  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]

• Pendular Nystagmus

  Associated with congenital blindness. optokinetic nystagmus nystagmus induced by looking at objects moving across the field of vision. oscillatory nystagmus pendular nystagmus. pendular nystagmus that which consists of to-and-fro movements of equal velocity [medical-dictionary.thefreedictionary.com]

  Differences in phase or amplitude between eyes is often seen in acquired pendular nystagmus. Acquired pendular nystagmus may be temporarily suppressed by saccades. [tchain.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]

• Hyperactivity

  Most of the affected individuals also showed absent optokinetic nystagmus and a hyperactive vestibulo-ocular response. Only two similar families have been reported previously. Full Text Download PDF Full Text Cite This Citation Marmor MF. [jamanetwork.com]

  The horizontal VOR is hyperactive (1276,1278) or normal (1283) Caloric tests frequently show increased responses, though a few may have absent caloric responses (1275). [neuroophthalmology.ca]

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]

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]

This is in contrast to other etiologies of congenital corneal clouding like Peter’s anomaly or a limbal dermoid, which can vary in size/location and often obscure underlying iris. [reviewofophthalmology.com]
