Congenital primary aphakia (CPA) is a rare eye condition that is present at birth in which the lens is missing. In some cases, CPA can be associated with other eye abnormalities including microphthalmia, absence of the iris, anterior segment aplasia, and/or sclerocornea (when the cornea blends with the sclera). This condition is thought to result from an abnormality during the 4th or 5th week of fetal development, which prevents the formation of any lens structure in the eye. Mutations in the _FOXE3 _gene have been associated with this condition. CPA is thought to be inherited in an autosomal recessive fashion. Click here to view a diagram of the eye.
