An undergraduate research conducted during the pre-covid times, to highlight the importance of screen time and its association with dry eye in medical students. The aim was to study the prevalence of dry eye among medical students using the ocular surface index (OSDI) questionnaire.
This was a cross-sectional study. This study was conducted among medical students using an OSDI questionnaire in the pre-covid times. Based on the pilot study, the minimum sample size calculated was 245. A total of 310 medical students participated in the study. These medical students answered the OSDI questionnaire. The OSDI score was used to categorize students with dry eye as mild (13-22 points), moderate (23-32 points), and severe (33-100 points). In addition, the associations between the OSDI score and possible risk factors such as gender, contact lens/spectacle wear, laptop/mobile usage, and duration of exposure to air conditioners were also studied.
The analysis of the study revealed that out of 310 students, dry eye was seen in 143 (46.1%) and severe dry eyes were seen in 50 (16.1%). A high OSDI score (>13 points) was associated with the usage of a laptop/mobile for more than 6 h in 40 (52.6%) (P < 0.001).
The prevalence of dry eye among medical students was 46.1% in the present study. Longer duration of usage of visual display units (laptop/mobile) was the only factor that showed a statistically significant association with dry eye in our study.
这是一项在新冠疫情前进行的本科生研究，旨在强调屏幕时间的重要性及其与医学生干眼症的关联。目的是使用眼表疾病指数（OSDI）问卷研究医学生干眼症的患病率。
这是一项横断面研究。本研究在新冠疫情前使用 OSDI 问卷对医学生进行。根据预试验，计算出的最小样本量为 245 人。共有 310 名医学生参与了这项研究。这些医学生回答了 OSDI 问卷。OSDI 评分用于将干眼症患者分为轻度（13-22 分）、中度（23-32 分）和重度（33-100 分）。此外，还研究了 OSDI 评分与可能的危险因素（如性别、隐形眼镜/眼镜佩戴、笔记本电脑/手机使用以及暴露在空调下的时间长短）之间的关联。
研究分析显示，在 310 名学生中，有 143 名（46.1%）患有干眼症，50 名（16.1%）患有严重干眼症。高 OSDI 评分（>13 分）与使用笔记本电脑/手机超过 6 小时有关，其中 40 名（52.6%）学生（P<0.001）。
本研究中，医学生干眼症的患病率为 46.1%。在我们的研究中，只有使用视觉显示设备（笔记本电脑/手机）的时间较长与干眼症有统计学显著关联。
