Methods 42 cases (48 eyes) of normal subjects with multi-focal ERG were detected by VERIS 40 visual evoked response imaging system. The subjects were 11 to 67 years old with an average age of 40.7 years. The horizontal field of view of the field of view was ± 2 6 6 ° and the vertical field of view was ± 2 2 1 °. Burian Allen contact lens electrodes were used to record 10 3 retinal responses over a period of 8 minutes (16 segments). Results The latency of N1 wave and P1 wave of multifocal ERG was prolonged with the age of the subjects, and there was significant difference between age <50 years and ≥50 years (t> 2.01, P < The amplitudes of N1 wave and P1 wave were significantly lower than those of the control group (P <0.05). The amplitudes of N1 wave and P1 wave were the largest among the individuals, and they were (4488 ± 1330) nV / deg2, ± 17 77) nV / deg2; the amplitude of the amplitude toward the periphery gradually decreased; the amplitude of the upper half of the N1 wave in the upper half of the retina was larger than that in the lower half of the retina; Conclusions Multifocal ERG can accurately and objectively reflect the function of different parts of the retina. Our findings will provide a normal reference for clinical
