摘要: 目的 调查正常视力、临床正位眼儿童在分视状态下眼位及注视稳定性的生理状况。设计 前瞻性病例系列。研究对象 97例5~7岁视力正常及临床眼位正常儿童。方法 应用基于计算机平台的视感知觉检查方法对正常儿童的知觉眼位与注视稳定性状况进行量化评估检测。主要指标 分视眼位差值与注视稳定性的对齐差值。结果 正常儿童注视银屏中点,相距80 cm时,3度注视视标其水平眼位4.73~6.83个像素,平均分离(5.78±1.51)个像素;垂直眼位2.12~3.31个像素,平均分离(2.72±0.85)个像素;1度注视视标其水平眼位5.64~8.06个像素,平均分离(6.85±1.74)个像素;垂直眼位1.37~2.03个像素,平均分离(1.70±0.48)个像素。注视稳定性对齐差值4.25~5.09个像素,平均为(4.67±1.03)个像素。结论 在视力发育正常、临床眼位正位的儿童中,水平分视的知觉眼位差值为4~8个像素,垂直分视的知觉眼位差值为1~3个像素可以作为生理范围参考;注视稳定性对齐差值为4~5个像素,可以作为生理范围参考。(眼科, 2014, 23: 312-315)

Abstract:  Objective To investigate the perceptual eye position and gaze stability of the children with normal visual acuity under dichoptic vision condition.  Design Prospective case series. Participants The study included 97 children with normal visual acuity and the age of 5 to 7 years. Method The main test method was the computer based visual perceptual test. The children should stare at the center of the screen, the distance between the child and the screen was about 80 cm. Each child must take the visual perceptual and gaze stability tests after regular ophthalmology examinations. Main Outcome Measures The deviation pixels of perception eye position and the gaze stability. Results When the target size was 3 degree, the horizontal eye position was 4.73~6.83 pixels, and the mean eye position was (5.78±1.51) pixels; the vertical eye position was 2.12~2.31 pixels, and the mean eye position was (2.72±0.85) pixels. When the target size was 1 degree, the horizontal eye position was 5.64~8.06 pixels, and the mean eye position was (6.85±1.74) pixels; the vertical eye position was 1.37~2.03 pixels, and the mean eye position was (1.70±0.48) pixels. The gaze stability deviation was 4.25~5.09 pixels, the mean deviation was (4.67±1.03) pixels. Conclusion The results of the perceptual eye position and gaze stability of this study may be taken as the clinical references of children with normal visual acuity.(Ophthalmol CHN, 2014, 23: 312-315)
