A primary attribute for proper functioning in life is gaze stabilisation. 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 stabilisation 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 computerised gadgets available to measure the 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 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 leads to a concrete diagnosis of neurological pathology.
This lecture discusses these eye movements with the author’s personal collection of more than 80 abnormal eye movements.
