Az IMEA ADR III kritikus fúziós frekvenciavizsgáló eszközzel végzett mérések reprodukálhatóságának
vizsgálata [Reproducibility of measurements using the IMEA ADR III critical flicker-fusion
frequency measuring device]
INTRODUCTION: Measurement of central critical flicker-fusion frequency is a common
screening test for eye diseases and additionally it can serve as a useful diagnostic
test in numerous neurological and internal diseases. The test might also be used for
monitoring purposes. AIM: The aim of the authors was to evaluate a digital central
critical flicker-fusion frequency measuring device (IMEA ADR III) in 30 young, healthy
Hungarian subjects. METHOD: After a general ophthalmological screening examination,
monocular central critical flicker-fusion frequency was measured with four colours.
Measurements were carried out on two separate days in three sessions under standardized
conditions. Intrasession, intersession and intervisit variabilities, differences in
central critical flicker-fusion frequency using the four colours and the effect of
certain other influencing factors were determined. RESULTS: There were no statistically
significant differences between sessions in the mean and standard deviation of the
measurement sets. The central critical flicker-fusion frequency threshold for red
colour was significantly lower than for other colours, and the threshold for blue
colour was significantly lower than for green. There were no significant differences
regarding sex, age, iris colour, and smoking indicating that these factors did not
influence the central critical flicker-fusion frequency threshold in these subjects.
CONCLUSIONS: Measurement results with the device are reliable and reproducible in
healthy, young population in separate sessions. Orv. Hetil., 2016, 157(27), 1079-1086.
