[Asthenopic symptoms in cervical vertebrae syndrome]

The vertebral cervical syndrome is a clinical entity defined as a dysfunction of the cranio-cervical junction of traumatic or non traumatic cause. The authors report on asthenopic disorders occurring in such a syndrome. The fusion amplitude and the accommodation power were reduced in all patients and were a cause of delayed job recurrence. The treatment of fusion was long, painful and, in some cases, not successful. A depressive status associated with a prolonged job interruption were bad prognosis factors. A differential diagnosis has to be made with the so-called insurance neurotic reaction.
