Abstract

• Fifteen patients with intentional or unintentional V1 lesions one to five years after percutaneous radiofrequency trigeminal rhizotomy were examined. No corneal changes developed in the majority of patients. These findings raise the question as to the precipitating factor(s) for neuroparalytic keratitis. The suggested mechanism for preservation of corneal function appears to be intact axonal mechanism(s).
