Cataract in early onset and classic Cockayne syndrome.

PURPOSE: To describe cataracts in classic and early onset Cockayne syndrome (CS). Classic CS typically has an onset after the first year of life; intrauterine growth failure and severe neurologic dysfunction from birth distinguishes the less common early onset CS from the classic form. METHODS: A complete ophthalmic evaluation was performed in four affected patients, one with the early onset and three with classic CS. RESULTS: We report cataract in all patients and glaucoma in one, the latter never previously reported in CS. CONCLUSION: CS should be considered in babies with low birth weight and congenital cataract.
