Primary congenital upper eyelid retraction in infants and children.

Four infants with unilateral or bilateral eyelid retraction were examined. A full clinical evaluation revealed no ocular or systemic pathology. In all cases, clinical examination, thyroid function tests, and neuroimaging of the brain and orbits revealed no underlying disease process. The eyelid retraction did not change over the follow-up period of 2 to 6 years. Unilateral or bilateral eyelid retraction in infants and children may be an isolated clinical entity without an associated underlying disease.
