摘　　要：目的调查弱视儿童在双眼分视状态下的眼位及注视稳定性的状况。设计前瞻性病例系列。研究对象临床眼位正常的弱视儿童,轻度、中度、重度各30例。方法应用基于计算机平台的视感知觉检查方法对弱视儿童的知觉眼位与注视稳定性状况进行量化评估检测。主要指标眼位差值与注视稳定性的对齐差值。结果弱视儿童注视3°视标其水平眼位均值:轻、中、重度组分别为(12.70±9.57)像素、(23.33±21.03)像素、(53.79±58.92)像素(H=14.765,P=0.001);垂直眼位均值分别为(4.93±5.21)像素、(9.23±9.03)像素、(20.48±23.75)像素(H=13.569,P=0.001)。注视1°视标其水平眼位均值:轻、中、重度分别为(18.67±16.19)像素、(33.27±27.95)像素、(81.61±76.02)像素(H=17.941,P=0.000);垂直眼位均值分别为(4.27±5.46)像素、(7.50±10.52)像素、(20.75±22.99)像素(H=19.927,P=0.000)。轻、中、重度组注视稳定性对齐差值平均分别为(4.77±3.18)像素、(7.23±5.54)像素、(20.44±22.99)像素(H=29.944,P=0.000)。结论临床眼位正位的弱视儿童其知觉眼位及注视稳定性均存在异常,弱视程度越深,异常越严重。弱视治疗应注重双眼视功能的改善。Objective To investigate the perceptual eye position and gaze stability of the children with amblyopia under dichoptic vision condition. Design Prospective case series. Participants 90 mild, moderate, severe amblyopic children with normal eye position, each include 30 cases. Method The main test method was the computer based visual perceptual test software, each amblyopic child must take the visual perceptual test and gaze stability test. Main Outcome Measures The deviation pixels of perception eye position and the gaze stability. Results When the target size was 3 degree, the mean horizontal eye position of mild, moderate, severe amblyopie children was 12.70±9.57, 23.33±21.03, 53.79±58.92 pixels respectively （H=14.765, P=0.001）; the mean vertical eye position was 4.93± 5.21, 9.23±9.03, 20.48±23.75 pixels respectively （H=13.569,P=0.001）. When the target size was 1 degree, the mean horizontal eye po- sition of mild, moderate, severe amblyopic children was 18.67±16.19, 33.27±27.95, 81.61±76.02 pixels respectively （H=17.941 ,P= 0.000）; the mean vertical eye position was 4.27±5.46, 7.50±10.52, 20.75±22.99 pixels respectively （H=19.927 ,P=0.000）. The mean gaze stability deviation of mild, moderate, severe amblyopic children was 4.77±3.18, 7.23±5.54, 20.44±22.99 pixels respectively （H=29.944, P=0.000）. Conclusion The deviation pixels of perception eye position and the gaze stability were abnormal in the amblyopic children with normal eye position. The more severe the degree of amblyopia, the more serious the abnormality. The treatment of amblyopia should focus on the improvement of the binocular vision.
