PLoS ONE 13(11):Įditor: Manabu Sakakibara, Tokai University, JAPAN The APL can increase the accuracy and save operating time of pupil diameter measurement and thereby promote the quality of health assessment and nursing care practice.Ĭitation: Chiou P-Y, Chien C-Y, Lai Y-H, Chun CF (2018) The effect evaluation of advanced penlight. The average scores of convenience and confidence on pupil diameter measurements of questionnaire were higher for the APL compared to the GPL. The average operational time was 8.72 seconds shorter (t = -3.81, p = 0.001) for the APL measurement compared to the GPL measurement. Compared to the GPL, the pupil diameter measured by APL was much similar to the RM measurement. ![]() There were no statistically significant differences between the average values of pupil diameters measured by the APL and the RM. The mean age of the participants was 20.01 (SD = 0.47) years and 83% of them were female senior nursing students. A self-administered questionnaire was used to assess the opinions of the participants after using the GPL compare to the APL. After standard pupil diameter measurements by a refractometer (RM) were performed on a subjects, ninety study participants measured the pupil diameters of the same subject separately by the GPL and APL. The PMR can be rotated by any angle for adaptation to the measurement conditions. The innovation of the APL is the addition of a perspective measurement ruler (PMR) attached to one side of the penlight that allows precise measurement of the pupil diameter before and after pupillary contraction. One-group post-test and single-blind study designed was used in this study. The purpose of the presented research was to compare the accuracies and operational times of the pupil diameter measurements by means of the GPL and APL. The Advanced Penlight (APL) is a new device designed for accurate measurement of the pupil diameter. Health caregivers or nurses generally have less confidence in the value of the pupil diameter measured using the GPL. A general penlight s (GPL s) is frequently used and allow for an approximate and indirect measurement of the pupil diameter. ![]() Pupil diameter measurement is crucial for physical assessment and disease monitoring in a health and nursing care situation. ![]()
