  • 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]
