摘要
立体视觉或深度感知能力下降可能是人类运动功能异常的早期指标,因此,立体视觉测试被认为是视觉筛查的理想选择。它可以通过使用具有成本效益的智能手机应用程序来完成对立体视觉评估的需要。目的:采用Lea Symbols (manual)和SAT App for Android (digital)进行随机点立体视敏度测试,比较手动立体视敏度和数字立体视敏度的差异。方法:于2023年2月至2023年5月在拉合尔大学教学医院眼科进行比较横断面研究。我们的研究共纳入了62名年龄在15-35岁之间的受试者,其中31名为正异性,31名为变异性。筛选受试者,包括火炬光检查和基本折射。人工立体视觉测量采用Lea符号随机点立体视敏度测试,数字立体视觉测量采用SAT软件。结果:手工测试(N=62)的平均±SD立体视敏值为60.5242±36.47607秒弧,数字测试(N=62)的平均立体视敏值为70.0968±28.29569秒弧。p值为0.006,证实我们的结果具有统计学意义。结论:我们的研究强调了数字和手动立体视觉测试的比较。我们从同一个体的两次测试中获得了不同的立体敏锐度值。因此,与数字测试相比,手动测试给出了更好的立体视觉值。
A Comparative Study of Manual and Digital Methods and Stereopsis Assessment in Young Adults
Reduced stereopsis or depth perception may be the early indicator of abnormal motor functions in people therefore, the stereopsis test is considered ideal for visual screening. It can accomplish the need for the assessment of stereopsis by using a cost-effective smartphone application. Objective: To compare the stereo acuity values of manual and digital stereopsis tests by using the Random Dot Stereo Acuity test with Lea Symbols (Manual) and the SAT App for Android (Digital). Methods: A comparative cross-sectional study was carried out in the Eye department at The University of Lahore Teaching Hospital from February 2023 to May 2023. A total of 62 subjects aged 15-35 years were included in our study, out of which 31 were emmetropes and 31 were ametropes. Screening of subjects was done which included torch light examination and basic refraction. Manually stereopsis was measured using Random Dot stereo acuity test with Lea symbols and digitally it was measured by SAT application. Results: The mean ± SD stereo acuity value of the manual test (N=62) was 60.5242 ± 36.47607 seconds of arc and the mean stereo acuity value of the digital test (N=62) was 70.0968 ± 28.29569 seconds of arc. P-value was 0.006 which confirmed that our results were statistically significant. Conclusions: Our study highlighted the comparison of digital and manual stereopsis tests. We obtained different stereo acuity values from both tests on the same individuals. Hence, the manual test gave better values of stereopsis than the digital test.
