Exodeviated Ophthalmoplegia in a Patient with Progressive Supranuclear Palsy

ABSTRACT

We report a patient with progressive supranuclear palsy (PSP) with his serial photographs before the onset of ocular symptoms and after the onset with two year intervals. These photographs show his progressive eyeball deviations toward complete exotropia. There were no effective voluntary eyeball movements, Bell's phenomenon, doll's eye movements, and vestibulo-ocular reflexes. These signs indicate the involvement of the oculomotor nuclear complex by the disease. We suggest that PSP may cause not only 'supranuclear' but also 'nuclear' complete ophthalmoplegia with exodeviation of the eyes.
