Normative Oculomotor and Vestibular Data in Pediatric Population

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to use a device called I-Portal® Portable Assessment System (I-PAS) to record eye movements in response to a number of visual and auditory stimuli designed to evaluate neural brain pathways related to oculomotor, vestibular, reaction time and cognitive (OVRT-C) development. The goal of this research is to collect normative data for the OVRT-C tests from a healthy pediatric population.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Normative data for I-PAS tests | Accuracy and gain across age: measurements of eye displacement versus stimulus displacement in saccadic and smooth pursuit tasks | 3 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Goggle evaluation | Short questionnaire consisting of 6 questions to assess the look, feel and weight of the goggles. 5 questions are Yes/No (0/1) and one question is on a rating from 0 to 3. The total score from these questions represents an evaluation of goggle comfort. The score can be between 0-8, where a score of 0 is indicative of a very good comfort level and a score of 8 of a low comfort level. | 3 years |
