摘要:

?目的：研究不同眼位患者在观看偏光3D影像0.5 h和1 h后视功能参数的改变，并探讨参数改变与视疲劳的关系。方法：选取志愿者51名，根据近距隐斜量分为3组：正位组、外隐斜组、内隐斜组。分别测量观看3D影像前、0.5 h和1 h 的视功能参数，使用视疲劳调查问卷进行视疲劳程度统计。结果：按眼位分，正位组和内隐斜组观看3D影像0.5 h和1 h 相比于观看前调节反应增大，差异有统计学意义（p=0.004、p＜0.001，p＜0.001、p=0.001）。内隐斜组观看0.5 h和1 h 立体视锐度值小于观看前，差异有统计学意义（p=0.02、p=0.03）。按时间分，观看0.5 h和1 h ，正位组和内隐斜组注视视差均小于外隐斜组，差异均有统计学意义（p=0.03、p＜0.001，p=0.02、p=0.007）。观看1 h后，正位组和内隐斜组的注视视差斜率绝对值均小于外隐斜组，差异有统计学意义（p=0.007、p=0.013）。观看0.5 h，外隐斜组视疲劳得分大于正位组和内隐斜组，差异均有统计学意义（p=0.034、p=0.015）。结论：不同眼位患者观看3D影像后，立体视锐度有所提升；调节反应增大、注视视差变大及其斜率的改变影响了双眼协调运动，最终导致视疲劳。

Abstract:

Objective: To observe the change of visual function after viewing polarized 3D images for thirty minutes and an hour for patients with different phorias and explore the relationship between the visual function parameters’changes and visual fatigue. Methods: According to near phorias, 51 volunteers were divided into three groups：normal phoria, exophoria, esophoria. Visual function parameters were measured before viewing polarized 3D images, after viewing half an hour and an hour later. The degree of visual fatigue was measured based on visual fatigue questionnaire. Results: According to phorias , at 30 mins and 1h after viewing the 3D images, the changes of accommodation response showed statistically significant difference（P=0.004,P＜0.001,P＜0.001,P=0.001）.The accommodation response of the patients with normal phoria and esophoria, increased. After half an hourand an hour(改为at 0.5h and 1h), the changes of stereoacuity showed statistically significant difference（P=0.02,P=0.03）.The stereoacuity of the patients with esophoria, decreased. According to the time point, at thirty minutes and 1 hour, the changes of fixation disparity presented statistically significant difference（P=0.03,P＜0.001,P=0.02,P=0.007）.The fixation disparity of the patients with normal phoria and esophoria , increased. At hour, the absolute value of the slope of fixation disparity had statistically significant difference （P=0.007,P=0.013）.The patients with normal phoria and esophoria was lower than those with exophoria .For the patients with exophoria ,the visual fatigue score increased at 0.5 h than normal phoria and esophoria with significant difference (p=0.034,p=0.015). Conclusion: The stereoacuity improves in different phorias after viewing 3D images.The increasing of accommodation response, fixation disparity and the slope of fixation disparity which affect binocular coordinated movement, eventually contributing to the visual fatigue.
