title: [Sensory status on Bielschowsky head tilt test].
abstract: The purpose of this work was to confirm ocular deviation during head tilt in cases of superior oblique muscle palsy. Ocular vertical deviation and cyclodeviation under head tilt loading were examined in nine cases with superior oblique muscle palsy using a new device, celled a modified phase difference haploscope (M-PDH). The M-PDH is able to measure a quantitative head tilt loading towards both sides. Tests using the M-PDH revealed the difference in angle of head tilt at the onset of hyperdrift and the degree of vertical deviation during head tilt towards the paretic side. Among the cases of superior oblique muscle palsy tested, ocular vertical deviation was classified into three types depending on the angle of head tilt.
