Chronic carbon monoxide poisoning resulting in bilateral cataracts and a cystic globus pallidus lesion.

The authors describe a case of a 43-year-old lady who developed bilateral cataracts, seizures and a unilateral cystic lesion of the basal ganglia following low-dose carbon monoxide (CO) exposure over 7 years. Cataract formation may result from sustained oxidative stress as a result of chronic environmental CO exposure.
