Cataracts, Anterior Polar 2

Background and History: 

Cataracts are opacifications of the lens in the eye.  There are multiple types and may be caused by a number of mechanisms including trauma, infections, metabolic errors, and gene mutations.  This is one of a number of congenital cataracts located at the front (anterior) surface.

Clinical Correlations: 

This type of cataract is present at birth and usually does not progress.  The opacity is located at the very front (anterior) of the lens in the form of a dot or small plaque.  There is usually little if any interference with vision.  No systemic abnormalities have been found.

 

Genetics: 

Most anterior polar cataracts occur sporadically.  In the few families reported, the pattern of transmission is parent-to-child as is characteristic of autosomal dominant disorders.  The gene mutation responsible has not been identified.

Diagnosis and Prognosis: 

Anterior polar cataracts are usually diagnosed by ophthalmologists.  The prognosis is excellent as they usually do not progress and surgery is seldom required.
