Vertical saccades in superior oblique palsy.
Vertical saccadic velocities in 10 patients who had unilateral superior oblique muscle palsy and 14 normal subjects were measured with the magnetic scleral search coil. The authors sought to determine whether downward saccades in patients who had superior oblique palsy are slow. Peak velocities of 10 degrees and 20 degrees saccades performed in the superior and inferior fields of the orbit, and...
متن کاملFacilitation of vertical vergence by horizontal saccades, found in a patient with dissociated vertical deviation.
The authors examined vertical vergence in a 15-year-old girl with dissociated vertical deviation, a 6d` convergent strabismus, no binocular vision, latent nystagmus, and a minimal left amblyopia. Eye movements were recorded during 4s-periods of (1) both eyes open, alternated with 4s-periods of (2a) right eye covered, (2b) left eye covered or (2c) both eyes closed. The patient preferred fixation...
متن کاملUp-down asymmetry in vertical vection
To investigate whether up-down asymmetry similar to that reported in vertical optokinetic nystagmus (OKN), that is, larger OKN responses for upward motion than for downward motion, would appear in vertical vection, we conducted three experiments. In all three experiments, participants viewed a vertically moving random-dot pattern. In Experiments 1 and 2, participants reported vection using a jo...
متن کاملConjugacy of eyelid movements in vertical eye saccades.
PURPOSE To examine the conjugacy of lid saccades in normal subjects. METHODS Saccades of both upper eyelids were recorded simultaneously by means of small, lightweight, magnetic search coils, fixed on each lid. Subjects then made vertical eye saccades between fixed targets. The associated eye saccades were recorded simultaneously by means of magnetic search coils. The authors further examined...
متن کاملVertical optokinetic nystagmus and saccades in normal human subjects.
PURPOSE Optokinetic stimulation induces nystagmus that can be used to test the saccadic and visual-tracking systems in some patients with voluntary gaze palsies. The purpose of this study was to characterize vertical optokinetic nystagmus (OKN) in normal human subjects, comparing the dynamic properties of the quick phases with voluntary saccades of similar size and measuring the slow-phase resp...
