ABSTRACT
Electroretinography has been used clinically for more than 50 years as useful retinal function test. But there has been no uniform recording signals, since various laboratories have employed different technologies and recording condition. Therefore, in 1989, International Society for clinical Electrophysiology of Vision (ISCEV) published Standard for clinical ERG, to ensure that ERG performed simply and uniformly worldwide for clinical and research purpose. We performed this standard ERG to 100 normal subjects whose range of ages were 8-79 years old. We obtained normal values of standard 5 basic response parameter. Additionally, we studied the parameter change according to age and sex. We found significantly decreased amplitude in the b-wave with age (p<0.05), and also obtained decreased rate b-wave amplitude with age. But no relation between b-wave implicit time and change of age was noted. B-wave amplitude found to be higher in women than in men (p<0.05).
