Video oculography (VOG) is a simple, non-invasive technique of recording eye movements using digital cameras. It could prove useful in the diagnosis of certain forms of myasthenia gravis, as proposed by Turkish clinicians in a study involving 18 myasthenic patients and 50 volunteers:
- the investigators used an EyeSeeCam device to measure eye saccades in several gaze directions,
- the myasthenic patients had a particular profile of movements in the vertical and horizontal gaze,
- VOG is of practical interest in forms where, clinically, oculomotricity disorders are difficult to perceive by the human gaze alone.
