FLICKER‐ELECTRORETINOGRAPHY

Acta Ophthalmologica, 1972
Flicker ERGs from normal human eyes are recorded using an averaging technique. After 300 msec the curve is in a stationary phase with strict periodicity. It is constructed by algebraic summation of individual flash responses with “head‐to‐tail” overlapping in higher frequencies. At a flash frequency of 25 cps.

Flicker photometry: residual minimum flicker

Journal of the Optical Society of America A, 1986
We show that when all possible optical artifacts are eliminated in a flicker photometric procedure, there is still a residual minimum flicker after color fusion occurs. The stimuli were alternated with approximately rectangular counterphase pulses and we obtained results contrary to those of a previous report where the stimuli were alternated ...

Critical Flicker Frequencies in Flicker Perimetry

Archives of Ophthalmology, 1968
Flicker fields from 270 individuals between 6 and 95 years of age were grouped into nine age ranges, each covering a decade and containing 30 individuals. For each decade, mean critical flicker frequencies were computed for 49 points of the visual field situated on the horizontal, vertical, and oblique meridians from 0° to 60°.
