Time-course of adaptations for electroretinography and pupillography

Cones are primarily involved in photopic vision and light adaptation. Rods responsible for scotopic dark The typical time-courses of adaptations have been known century. However, information regarding the minimal adaptation time electroretinography (ERG) pupillography would be helpful practical applications clinical efficiency. Therefore, we investigated relationship between parameters ERG pupillography. Forty-six eyes 23 healthy women (mean age, 21.7 years) were enrolled. tested right left eyes, respectively. with a skin electrode was used to determine amplitude (µV) implicit (msec) by records rod-, flash-, cone-, flicker-responses white (0.01–30 cd·s/m2). Infrared record pupillary response 1-sec stimulation red (100 cd/m2). Cone- flicker- (rod-, pupil) responses recorded after (dark) at 1, 5, 10, 15, 20 min. Amplitude significantly different 1 min ≥5 or ≥10 b-wave cone- rod-response, Implicit differed rod-response. There significant differences parameter minimum pupil diameter constriction rate, Consequently, light-adapted ERGs can recorded, even 5 without special condition, whereas dark-adapted results obtained 10 longer complete darkness.
