To investigate the characteristics of waveform generated by blue and red light stimulations in a dark-adapted electroretinogram (ERG) those cone responses condition.The study subjects were 52 persons (88 eyes) with no previous medical history. The author recorded b-waves (rod response) stimulation x-waves (dark-adapted that appeared before b-waves. also stimulation, which had same amplitude as from stimulation. differences respect to age gender studied. Waveforms ERGs using digital subtraction technique.The x-wave always b-wave 0 dB (2.4 cd.s/m2) With equivalent stimulated intensity at an average -14.57 dB. implicit time for was delayed significantly male group. There significant between different groups. ERG demonstrated negative response followed series oscillatory potentials (OPs) positive response.The rod ERG. waveforms obtained dark adaptation
