Cone Electroretinography by Flicker [PDF]

Nature, 1951
IT is generally assumed that the b-wave of the human retinal action potential is due to the stimulation of the rods. With an intensity of 2,000 lux, the b-waves fuse at a frequency of about 20 flashes per second. At lower intensities the fusion frequency in our experiments decreased.

Potentiality of Evaluating Flash Electroretinography with a Montage of Skin Electrodes Connecting the Inner Canthus to the Ear in Younger Children: A Pilot Study [PDF]

This study aimed to determine whether more stable electroretinography parameters could be obtained in younger children using skin electrodes placed at the inner canthus and ears compared to using contact lens electrodes. The study included three Japanese

Protective Effect of Prunus Cerasus (Sour Cherry) Seed Extract on the Recovery of Ischemia/Reperfusion-Induced Retinal Damage in Zucker Diabetic Fatty Rat

Molecules, 2017
Among diabetes patients, ophthalmological complications are very frequent. High blood glucose and (consequential) ischemia-reperfusion (I/R) injury contribute significantly to the severity of retinopathies.
