两种随机点立体视检查法在临床应用比较

The application comparison of two kinds of random-dot stereopsis inspection methods in clinical work

目的比较两种随机点立体视检查方法的差异。方法选用颜少明等联合研制的《立体视觉检查图》与金贵昌等联合研制的《双眼立体视觉检查图》，对一组5～7岁的儿童，在视力、眼位正常的前提下，在相同的环境中进行立体视锐度的检查。结果共检查128人，对两种检查方法的结果进行配对t检验，其结果差异有统计学意义（t=12．49，P〈0．01）。结论在应用两种随机点立体图进行近立体视锐度的检查中。

Objective To compare the difference of two kinds of random-dot stereopsis inspection methods. Methods Using the ＂Stereovision Inspection graph＂ which was developed by Yan Shao-ming and the ＂Binocular Stereovision Inspection graph＂ which was developed by Jin Gui-chang, the stereopsis acuity examination was performed to a group of 5-7 year-old children whose vision and the eye position were normal under the same environment. Results Two groups of 128 children were examined using two kinds of inspection methods and the matching t-test was done to the results. There were statistical significant differences between two groups （ t =12.49, P 〈 0.01 ）. Conclusions Two different stereovision inspection graphs used in this study to examine the children＇s stereopsis acuity showed significant differences between two testing results.
