摘　　要：目的通过对屈光不正患者不同视光条件下立体视锐度和视差的分析,了解立体视觉的影响因素。方法测量85例门诊屈光不正志愿者立体视指标,对年龄、屈光参差、远近视力、调节性辐辏与调节比(AC/A)等因素与远近立体视锐度、交叉视差及非交叉视差进行相关分析。结果远立体视锐度与四种因素均不相关;近立体视与屈光参差及近视力呈正相关;交叉视差与屈光参差及近视力呈负相关;非交叉视差与近视力呈负相关。结论立体视功能各项指标有各自独立或共同的影响因素。立体视是受多因素影响的。Objective To find out the influential factors of stereopsis through the analysis in ametropic cases. Methods Eighty - five volunteem with different age, anisometropic status, visual acuity and AC/A were tested to get their stereoacuity, crossed stereopsis and uncrossed stereopsis, After that, the data of their stereopsis were compared, Results There was no correlation among far stereoacuity and four factors. Near stereoacuity had positive correlation with anisometropic status and near visual acuity. Crossed stereopsis had negative correlation with anisometropic status and near visual acuity. Uncrossed stereopsis had negative correlation with near visual acuity. Conclusion Stereopsis is influenced by various factors.
