Figure

  • Fig. 1 Evaluation of diplopia, ocular torsion and vestibular function tests. A: An ocular motility test with a Hess-Weiss screen showed hypertropia of the left eye (skew deviation to the right). B: Fundus photographs indicating 20° extorsion of the right eye and 2° intorsion of the left eye. C: Video head impulse tests showed a decreased vestibulo-ocular reflex gain with corrective catch-up saccades of the right PC (normal gain=0.88–1.06), but normal gains for the left posterior and both the AC (normal gain=0.91–1.07) and the HC (normal gain=0.88–1.03). D: Cervical vestibular-evoked myogenic potentials showed symmetrical responses (an interaural difference at 16%, normal range <22%). AC: anterior semicircular canal, HC: horizontal semicircular canal, LE: left ear stimulation, PC: posterior semicircular canal, RE: right ear stimulation.
