医务人员终端视频的多焦视网膜电图临床调研
The Clinical Research of the Multifocal Retinal Electric Diagram about Medical Staffs’ Terminal Video

目的：观察医务人员长期终端视频多焦视网膜电图的临床变化，探讨视频终端对黄斑视功能的早期影响。方法：收集我院中青年临床医务工作者共25例(50眼)，按每日累计终端视频使用时间分为对照组(<8 h)、观察组(≥8 h)，采用罗兰RETI-Port/scan 21多焦电生理系统(mf-ERG)进行黄斑区视网膜功能检查，记录黄斑中心凹自内至外的1环(2.18度)、2环(7.46度)、3环(12.36度)、4环(19.66度)、5环(29.75度)的N1波和P1波振幅密度和峰时，应用SPSS 18.0软件，统计学处理方法采用t检验进行组间比较，左–右两眼之间采用配对t检验比较。结果：两组间性别、年龄、主视眼差异无显著意义(P > 0.05)，mf-ERG 1环、4环、5环的N1、P1波的振幅密度、峰时两组间差异无统计学意义(P > 0.05)，组内左右两眼差异无统计学意义(P > 0.05)。2环左眼P1波峰时两组间差异有显著性(P < 0.05)，观察组P1波峰时左右两眼间差异有显著性(P < 0.05)，3环左眼n1波振幅密度、右眼n1波峰时两组间差异有显著性(P < 0.05)，观察组p1波峰时左右两眼间差异有显著性(P < 0.05)。结论：mf-ERG客观反应出平均每日使用8 h以上视频终端，黄斑中心凹旁区视网膜感光细胞振幅有降低，峰时延迟，说明终端视频发出的蓝光长期注视可导致黄斑中心凹旁区视网膜感光细胞功能反应下降，具有潜在破坏性，为安全、正确使用终端视频时间提供参考。
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;
