Congenital hereditary endothelial dystrophy
Congenital hereditary corneal dystrophy (CHED) is a form of corneal dystrophy which presents at birth.
CHED has two types:
- type I or the autosomal dominant form.
- type II or the autosomal recessive form is linked to mutations in SLC4A11 gene
In the recessive form corneal clouding is observed at birth or within the neonatal period, nystagmus is often present, but no photophobia or epiphora is seen. In the autosomal dominant type corneal opacification is usually seen in the first or second year of life and progresses slowly, and nystagmus is infrequently seen.
