不同年龄人群的立体视觉检查与比较

摘要

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.%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1039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<0.001)；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。
