What is convergence deficiency and what causes it? Could it be caused by premature birth?
The medical term for a convergence deficiency is "convergence insufficiency." It refers to an abnormally reduced ability to converge or utilize the eyes together for near activities such as reading. The problem is not caused by premature birth. Children born prematurely, however, often have neurologic impairment, and the condition is more common in children with some forms of neurologic impairment. The vast majority of children with convergence insufficiency are completely normal otherwise.
