Abstract
The video retinoscope presented here makes it possible for the first time to interactively demonstrate, discuss, evaluate and document optical phenomena with the aid of an integrated touch display. The precision in relation to the objective refraction results between the conventional retinoscope (CS) and video retinoscope (VS) is comparable (p = 0.093, Wilcoxon test). On the basis of questionnaires using visual analogue scales (0 = very unfavorable/10 = very favorable; subsequently the median/interquartile range is given) during a pilot study, 12 test persons rated the CS (VS) with respect to the feasibility of continuous light band movements with 6.9/1.3 (6.0/4.2) and the ease of use with 8.1/2.1 (8.9/1.6) out of a maximum of 10 points each and thus both retinoscopes as equivalent. In terms of weight, the subjects favored the conventional retinoscope with a rating of 8.7/2.2 (4.0/4.8).
