摘　　要：目的 :了解不同年龄人群的立体视觉现状与规律 ,为开展立体视觉检查与评价提供参考 ;提出一种新的立体视觉检查工具与方法。方法 :选用全息立体视觉检查仪 ,用相同方法 ,对四组不同年龄人群进行立体视觉的检查和分析。结果 :共检查 10 39人 ,立体视锐度总正常率为 82 .6 %。其中 ,学龄前儿童组立体视觉正常率是 86 .9% ;学生组最高为 98.0 % ;青壮年组次之为 94.7% ;老年组的立体视觉正常率明显降低为 35 .4% ,立体视盲的比例明显增加。结论 :年龄与立体视觉之间明显相关 (P <0 .0 0 1) ;各年龄组立体视觉正常率与近视力关系密切 ;全息立体视觉检查仪可作为一种新的、可靠的检查工具在临床上推广使用。Objective:To find out the current conditions and regular pattern of stereopsis of the different age groups, to offer reference for the examination and evaluation of stereopsis and propose a new steropsis test device. Methods:The stereopsis of the four different age groups was examined with the holographic stereopsis test facility in the same procedure.Results:According to the results of statistics, the percentage of normal stereopsis acuity is 82.6% in the total 1039 cases examined, of which 86.9% in the preschool children group, 98.0% in the student group,94.7% in the young adults group and 35.4% in the old people group respectively. The percentage of stereopsis blindness in the old people group is 12.4%,which is by far higher than that of the others.Conclusion:The stereopsis acuity examined in this study is closely related to the age by χ2 text(P<0.001) and the near vision acuity. It is suggested that the holographic stereopsis text facility can be used more comprehensively as a new reliable stereopsis test device.
