In Reply.  —All three children described in our article1 were followed up by a pediatric neurosurgeon who obtained computed tomographic scans of the head before and after each shunt revision and also during follow-up. The lateral ventricles were dilated before and reduced in size after surgery. One child had chronic intracranial pressure monitoring before revision, and the pressure level was elevated. Visual evoked potential studies were done in all children but, unfortunately, not consistently both before and after shunt revision.
