Abnormal spatial localization in patients with herpes zoster ophthalmicus. Evidence for the presence of proprioceptive information
E. C. Campos, C. Chiesi and R. Bolzani
Patients with herpes zoster of the ophthalmic branch of the trigeminal
nerve and normal ocular motility were examined. They were asked to point to
targets without the sight of their own hand. Significant errors were found
on the affected side. Proprioceptive information of the extraocular muscles
is assumed to travel in the trigeminal nerve, and these results thus
suggest the existence of peripheral afferent signals influencing eye-hand
coordination.
