Ocular flutter and opsoclonus are intermittent bursts of involuntary conjugate eye oscillations, in the horizontal multidirectional planes, respectively, without intersaccadic intervals. Patients with ocular flutter/opsoclonus often present oscillopsia vertigo, sometimes cerebellar ataxia myoclonus. can be caused by various diseases, such as postinfectious encephalitis, paraneoplastic syndrome,...

background: the cervical spine is the most vulnerable part of the vertebral column and the rotational movements are the most dangerous movements which may cause damages to cervical spine. a good treatment option for the cervical disc disease is the replacement of a damaged disc with an artificial disc that has shown satisfactory clinical results. methods: the c4 to c6 vertebrae of a normal subj...

This paper presents a novel three-dimensional (3-D) eye movement analysis algorithm for binocular eye tracking within virtual reality (VR). The user's gaze direction, head position, and orientation are tracked in order to allow recording of the user's fixations within the environment. Although the linear signal analysis approach is itself not new, its application to eye movement analysis in thr...

Psychophysical studies extending over a thirty-year period have repeatedly demonstrated that visual stimuli presented close to the onset of a saccadic eye movement are mislocalised both spatially and temporally. When post-saccadic visual references are available, this spatial distortion is best characterised by a compression of visual space toward the target of the saccadic eye movement. An imp...
