Abstract: Objective: To observe the clinical changes of long-term video multifocal electroretinogram in medical staff and to explore the early effect of video terminal on macular visual function. Methods: We collect 25 cases (50 eyes) of our young and middle-aged clinical medical workers, who are di-vided into control group (<8 h) and observation group (8 h or higher), according to the daily video terminal use time. Using the Roland RETI-Port/scan 21 focal electro physiological System (my-ERG) in the macular area retinal function to record the macular center concave from inside to outside 1 ring (2.18˚), 2 rings (7.46˚), 3 rings (12.36˚), 4 rings (19.66˚), 5 rings (29.75˚) of N1 wave and P1 wave amplitude density and peak while SPSS 18.0 soft-ware was used for statistical processing and t-test was used for comparison between groups. Paired t-test was used for comparison between left and right eyes. Results: There was no significant difference in gender, age and dominant eye between the two groups (P > 0.05). There was no statistically significant difference in amplitude density and peak time of N1 and P1 waves in mf-ERG ring 1, 4 and 5 (P > 0.05), and no statistically significant difference between the left and right eyes (P > 0.05). There was a significant difference between the two groups at the peak of P1 in the left eye of the 2 ring (P < 0.05); there was a signifi-cant difference between the two groups at the peak of P1 in the observation group (P < 0.05); there was a significant difference between the two groups at the peak of n1 wave density in the left eye of the 3 ring and n1 wave density in the right eye (P < 0.05); and there was a significant difference be-tween the two groups at the peak of P1 in the observation group (P < 0.05). Conclusion: mf-ERG ob-jectively reflects the average daily use more than 8 h video terminals; macular center near the con-cave area retinal photoreceptor cells have reduced amplitude; the peak latency uncovers the fact that blue light from the terminal video watched for a long time may cause macular center near the concave area function in retinal photoreceptor cells decreasing, which is potentially damaging. This provides a reference for safe and correct use of terminal video time.

1) 两组间性别、年龄、主视眼比较差异无统计学意义(P > 0.05)。

2) 两组间mf-ERG各环N1、P1波振幅密度、峰时比较：一环、四环、五环N1、P1波的振幅密度、峰时两组间及组内差异无统计学意义(P > 0.05)。2环两组间比较，左眼p1波峰时差异有统计学意义(P < 0.05)；左–右两眼配对t检验，仅观察组的P1波峰时左右两眼间差异有统计学意义(P < 0.05) (见表1)。3环两组间比较，左眼n1波振幅密度、右眼n1波峰时差异有统计学意义(P < 0.05)；左–右两眼配对t检验，仅观察组p1波峰时左右两眼间差异有统计学意义(P < 0.05) (见表2)。
