Abstract
Paralytic strabismus shows limited eye movements with, not only holizontal but also vertical and/or cyclotrosional deviation. Especially, it is difficult to diagnose vertical and cyclotorsional strabismus on the basis of its appearance or eye movements. Therefore, some patients were misdiagnosed with psychosomatic disorder or feigned illness, even though they were suffering asthenopia or persistent diplopia. Opthalmologists should diagnose paralytic strabismus that based on accurate orthoptic examinations.
I describe the important reminders of the examinations orthoptists should performe, in the cases of paralytic strabismus, i.e., abducens and trochlear palsy.
