Abstract

INTRODUCTION

Stereopsis is defined as the ability to perceive object depth. It is measured in seconds of arc. Reduced stereoacuity impinges one's academic as well as a professional performance. Hence in this study, we aim to find out the mean stereoacuity among the undergraduate medical and nursing students using the Titmus fly test.

METHODS

A descriptive cross-sectional study was conducted among undergraduate students at a medical college of Nepal from April 2021 to July 2021. Ethical approval was obtained from the Institutional review committee (Registration number: 487 (6-11) E2 077/078). Simple random sampling method was used. Data were collected from undergraduate medical and nursing students while the post-graduate students were excluded from the study. Overall, 80 students were included in the study. Titmus fly test was used to assess the stereopsis. Statistical Package for Social Sciences version 21 and Microsoft Excel was used for data analysis. Point estimate at 95% confidence interval was calculated along with mean, standard deviation, frequency, and proportion.

RESULTS

The mean stereoacuity was 62.63±46.56 (range 40-800) sec of arc (52.77-72.49 at 90% Confidence Interval). A total of 80 participants in our study among which 50 (62.5%) were male and 30 (37.5%)were female. About 41 (51.2%) of the study participants had normal, borderline (>40 and ≤ 120) stereopsis was seen in 35 (43.8%) of the study participants while only 4 (5%) had reduced stereopsis (≥120 sec of arc).

CONCLUSIONS

This study showed that the mean stereoacuity among the undergraduate medical and nursing students was in subnormal range which was similar to other studies.

摘要

简介

立体视是感知物体深度的能力。它以角秒为单位进行测量。立体视锐度降低会影响一个人的学术和专业表现。因此，在这项研究中，我们旨在使用Titmus 立体镜测试来确定尼泊尔一所医学院的本科医学生和护生的平均立体视锐度。

方法

这是一项在尼泊尔一所医学院进行的描述性横断面研究，时间为 2021 年 4 月至 2021 年 7 月。该研究获得了机构审查委员会的伦理批准（注册号：487 (6-11) E2 077/078）。采用简单随机抽样法。研究对象为本科医学生和护生，不包括研究生。共有 80 名学生纳入研究。使用 Titmus 立体镜测试评估立体视锐度。使用社会科学统计软件包 21 和 Microsoft Excel 进行数据分析。计算了 95%置信区间的点估计值以及平均值、标准差、频率和比例。

结果

平均立体视锐度为 62.63±46.56 秒（范围为 40-800）（90%置信区间为 52.77-72.49）。我们的研究共纳入 80 名参与者，其中 50 名（62.5%）为男性，30 名（37.5%）为女性。大约 41 名（51.2%）的研究参与者的立体视锐度正常，35 名（43.8%）的研究参与者的立体视锐度处于边界范围（>40 和≤120），只有 4 名（5%）的研究参与者的立体视锐度降低（≥120 秒）。
