Davis Visual Scan Test Normative Data For A Sample.

Purpose: .The purpose of this study is to provide normative data for the Davis Visual Scan Test (DVS Test). Method: Subjects will be selected at random from the Michigan College of Optometry (MCO) Clinic in Big Rapids, MI and a private optometrist's practice in Grand Rapids, MI. The subjects must have experience using a pencil in a paper and pencil task, otherwise no other restrictions apply to the selection of subjects. The Davis Visual Scan Test will be administered to the subjects, and the data will be recorded. Results: The data was recorded and statistically analyzed to determine normative data for performance on the DVS Test in the different age ranges of the randomly selected subjects that were selected. It was found that the mean score was 44.33 with a standard deviation of 11.46. The mean age was 25 years. Conclusion: Normative data for the DVS Test will be useful to clinicians for diagnosing a problem with visual scanning ability. This will further lead to the proper focus oftherapy for the
patient.
