Can central eye movement disorders be a window to brain function?
A primary attribute for proper functioning in life is gaze stabilization. This enables a subject to track objects, orient in space, and perceive a three-dimensional existence. The process is a complex interplay between peripheral sensors and the brain sending signals thereafter to oculomotor and spinal muscles. The vestibular system plays an important role in gaze stabilization in response to gravity and to motion and connects with vast tracts in the brain that leads to final integration and perception.
Therefore, it is intuitive to understand that eye movements reflect this integration process, and if there are deficits in the system, these movements become abnormal. There are sophisticated computerized gadgets available to measure eye movements and their abnormalities. Since control of eye movements in the brain is highly site and topography specific, different abnormalities indicate the site of lesion in different areas of the brain that are extremely sensitive and may predate imaging findings. To date, more than 50 different eye movements are known, all of which tell a story and lead to a concrete diagnosis of neurological pathology.
SYNAPSYS Video-scope is a new Video-Frenzel system by Inventis fully controllable by the diagnostic software Maestro, which allows video recording of the eye with or without an environmental image and also video playback or extraction. A basic solution for eye movement visualization and analysis. Suitable for both diagnostic and rehabilitation purposes, with SYNAPSYS Video-Scope, the user can choose between a standard wired camera configuration or the flexibility and unique advantages of a wireless system which provides an unprecedented user experience in terms of patient mobility, freedom of movement, and flexibility of use, offering great advantages in performing especially Dix-Hallpike maneuvers.
