目的探讨视盘晕大小与瞳孔对光反应、近视的关系。设计横断面研究。单位单一屈光手术中心。参与者在这项研究中，197例20至35岁之间的患者的197只右眼进行了评估的磁盘晕的大小和瞳孔对光的反应与视力监视器。主要和次要结果测量晕半径、年龄、等效球镜（SE）、眼轴长度（AL）、初始直径、收缩幅度、收缩潜伏期、收缩持续时间、收缩速度、扩张潜伏期、扩张持续时间、扩张速度、最大瞳孔、最小瞳孔、平均瞳孔和暗瞳孔。结果视盘晕大小与SE（r=-0.219，P =0.002）、AL（r=0.152，P=0.033）和最小瞳孔（r=0.149，P=0.037）显著相关。视盘晕大小与初始直径、收缩幅度、收缩潜伏期、收缩持续时间、收缩速度、扩张潜伏期、扩张持续时间、扩张速度、最大瞳孔、平均瞳孔、暗瞳孔及年龄均无相关性（P>0.05）。在低度-中度和高度近视（SE<-6 D）组之间（P=0.002）以及小和大（最小瞳孔≥4 mm）最小瞳孔大小组之间（P=0.014），检测到视盘晕圈大小存在显著差异。结论高SE、最小瞳孔直径大（最小瞳孔直径≥4 mm）的患者比低SE、最小瞳孔直径小的患者更易发生失能眩光。
Objectives To evaluate the relationship between pupillary response to light, myopia and disk halo size. Design Cross-sectional study. Setting Single refractive surgery centre. Participants In this study, 197 right eyes of 197 patients between 20 and 35 years of age were evaluated for disk halo size and pupillary response to light with a vision monitor. Primary and secondary outcome measures Halo radius, age, spherical equivalent (SE), axial length (AL), initial diameter, amplitude of contraction, latency of contraction, duration of contraction, velocity of contraction, latency of dilation, duration of dilation, velocity of dilation, maximum pupil, minimum pupil, average pupil and dark pupil. Results Significant associations were found between disk halo size and SE (r=−0.219, P=0.002), AL (r=0.152, P=0.033) and minimum pupil (r=0.149, P=0.037). There were no associations between disk halo size and initial diameter, amplitude of contraction, latency of contraction, duration of contraction, velocity of contraction, latency of dilation, duration of dilation, velocity of dilation, maximum pupil, average pupil, dark pupil and age (P>0.05). A significant difference in disk halo size was detected between the low-moderate and high myopia (SE< −6 D) groups (P=0.002) and between the small and large (minimum pupil≥4 mm) minimum pupil size groups (P=0.014). Conclusions Patients with a high SE and large minimum pupil size (minimum pupil ≥4 mm) suffered more disability glare than those with a low SE and small minimum pupil size.
