Eye Tracking (Ocular Motility)
Ocular Motility involves the 6 external muscles around each eye working equally to move the eyes into different positions (up, down, left right, and 4 corners). Problems with ocular motility can occur following nerve palsies or caused by mechanical restrictions of the muscles to move (e.g. trapped muscles).
​
​Eye Tracking, describes the eye movements that allows a person to fix their eyes on an object and smoothly follow it as it moves, or follow a sentence on a page from left to right. Eye tracking also includes eye-hand coordination skills.
​
Eye tracking skills are particularly important in sports such as football, soccer and tennis.
Symptoms of a breakdown in eye tracking include:
-
Skipping over words when reading,
-
Re-reading words or lines unintentionally,
-
Over-reliance on finger or ruler to keep place while reading (in children), and
-
Excessive head movements during desk work.
​
​
Eye Tracking skills are made up of 3 components:
-
Fixation - keeping the eyes steady without looking away from a target/object.
-
Saccades - accurate jumps between objects without overshooting or undershooting.
-
Pursuits - the ability of the eyes to remain fixated on a target/object as it moves.
