Living with Congenital blue dot cataract

An eye condition with bluish or whitish cloudy areas in the lens, present at birth or appearing early in childhood.

Understanding Congenital blue dot cataract

Congenital blue dot (cerulean) cataract is a condition with cloudy areas, often bluish or whitish, in the lens of the eye.

It may be present at birth or develop in early childhood, but may not be diagnosed until adulthood. It usually affects both eyes and gets worse over time. Infants can have no symptoms, or may have poor vision from birth, shaky eye movements (nystagmus) or lazy eye (amblyopia).

Signs & symptoms

Symptoms vary from person to person. GARD's summary lists these features:

  • Cloudy bluish or whitish areas in the eye lens
  • Usually affects both eyes
  • Reduced vision
  • Shaky eye movements (nystagmus)
  • Lazy eye (amblyopia)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
