Presenile cataracts

What it means

Presenile cataract is a kind of cataract that occurs in early adulthood, that is, at an age that is younger than usual.

Presenile cataract is rare. Some cases have a hereditary cause; others result from trauma or chromosomal, endocrine, metabolic, or systemic disorders. Many cases are idiopathic. The term 'presenile' is used differently in the literature. The HPO defines it to mean a cataract that is diagnosed after the age of 20 years but before old age.
