Abstract

Abstract: : Purpose:The spontaneous eyeblink activity in the primary gaze position and its relationship to age and sex were assessed using image processing techniques to quantify the eyeblink opening (EOT) and closing time (ECT). Methods:180 healthy volunteers (90 males and 90 females) separated into age groups (0-3, 4-12, 13-20, 21-40, 41-60 and ≷ 60 years-old) were prospectively evaluated. The subjects were digitally videotaped in a standard setting and the images were transferred to a personal computer (Macintosh 400) and processed with iMovie software. The EOT and ECT were measured using frames scale. The data were submitted to statistical analysis. Results:ECT was significantly higher than EOT in all age and sex groups. Elderly individuals (≷ 41 years-old) and women presented significantly higher ECT. Conclusion:It was possible to observe differences on the opening and closing time of the spontaneous eyeblink rate according to age and sex with the image processing techniques used in this study.
