Correlation between the c wave and the corneoretinal potential in man.
In the human DC-ERG the amplitude of the slow negative potential is modulated by the corneoretinal potential as well as the c wave. Depending on the phase of the slow oscillation of the corneoretinal potential some subjects show a c wave and others do not. Some subjects, who show a c wave during the maximum of the slow oscillation, have no c wave during the minimum, but show the slow negative potential. A hypothesis of slow oscillation influence on the c wave is given.
