PURPOSE To investigate the effect of diffuse luminance flicker of different frequencies on retinal vessel diameter in the human eye. METHODS Nine healthy subjects participated in the study. A retinal vessel analyzer (RVA; Zeiss, Jena, Germany) was modified to allow for continuous measurement of vessel diameter during flicker stimulation. With this technique, the light used for measurement of vessel diameter consists of wavelengths between 567 and 587 nm, whereas the spectrum of the… CONTINUE READING
