| Résumé : | The amplitude of the early receptor potential (ERP) produced by a given flash in the human eye provides a measure of the amount of visual pigments present in the eye. After a flash of very high intensity and short duration (1 msec) the ERP to a weaker second flash delivered 2 sec later is not reduced in amplitude below 15 to 24% of the ERP produced by the same flash in the dark adapted eye. This suggests a proportional reduction of the amount of visual pigments still present in the eye after the bleaching flash, which is in agreement with fundus reflectometry results of Weale for the human retina. |
