Abstract

  The movements of the eye, such as smooth pursuit, saccades and eye tracking are called Oculo Motor Behavior (OMB). Eye tracking is being increasingly used to examine oculomotor behavior (OMB) for visual and neurological health and normative studies like this has relevance in this context.

The aim of this study was to

  The test was carried out on a volunteer group of healthy individuals, via an infrared camera, and digital analysis tracking of the pupil. The Oculomotor Saccadic tracking was done for different groups both in Horizontal and Vertical directions and in 2 speeds i.e. 0.3Hz and 0.45Hz. The parameters analyzed were Velocity, Precision and Latency.

  Across all the groups, when these parameters were studied, there was a definite influence of age groups but no statistical difference between these values in males and females. The results argue for the necessity of using such normative values in the assessment of OMB metrics in patients of a particular age group, and the necessity for using contralateral assessments in comparing values obtained from individual patients.
