1. Smooth Pursuits __ampersandsignndash; the ability to stabilize gaze and follow a moving object with the eyes accurately.&#13;
2. Saccades __ampersandsignndash; the ability to move eyes accurately from one target to another. Saccades are necessary for tracking skills while reading or copying information. In order to process visual information properly, the eyes must move smoothly and quickly from one object to another.&#13;
3. Convergence/Divergence __ampersandsignndash; the ability of the eyes to move inward/outward in order to focus on an object and keep it single as it moves near/far.&#13;
In oculomotor dysfunctions, a person may have difficulty reading. He may lose place while reading or repeat sentences. He may also have difficulty with balance, depth perception, sports, or hand eye coordination. Children suffering from autism spectrum disorder haveproblems with eye contact and also have eye movement disorders.&#13;
Currently validated procedures to measure oculomotor abilities require verbalization, cognition and comprehension on the part of the subject. This is done in the form of reading out the numerals/alphabets subjectively and or/ follow instructions of the examiner. This becomes difficult for subjects who are unable to communicate and comprehend. An objective, non-verbal software was designed to objectively evaluate the ocular movements.&#13;
Methods: Commercial Tobii eye tracker was used with a software (developed to objectively measure ocular movements). This was validated against NSUCO, which is a validated procedure. NSUCO, however requires understanding and comprehension.&#13;
Results: The equipment was designedand validated against NSUCO. It was found to correlate well with it. Repeatability, inter and intra observer reliability was tested and found to be good.&#13;
Conclusion: Thenew equipment allows an eye care professional to objectively and quantitatively evaluate eye movements innon-communicating individuals.&#13;
