目的：评估马来西亚一所私立大学使用视觉显示装置(VDU)的学生非斜视双眼视觉异常(NSBVA)情况。

方法：对2019-01/2019-05期间每天使用3h及以上VDU的大学生进行横断面研究。使用一种简便的样本收集方法，所有受试者均通过初级视力检查且满足入选标准，对符合入选标准的学生进一步进行NSBVA评估。采用描述性分析排除NSBVA的百分比，采用Chi-square独立性检验，观察NSBVA与年龄、性别、VDU使用时间的相关性。

结果：研究共纳入140名学生，其中女88名(62.9%)，男52名(37.1%)。受试者平均年龄为22.54±1.48a，平均VDU使用时间为5.76±2.49h。使用VDU学生的NSBVA百分比为40%。在VDU使用者中，调节异常和倾斜异常的发生率分别为17.86% 和22.14%。性别与NSBVA之间存在适度关联(P=0.010)。但是，年龄(P=0.334)和VDU使用时间(P=0.835)与NSBVA无显著相关。

结论：马来西亚一所私立大学的学生中，有40%的人使用VDU。在所有NSBVA中，VDU用户调节异常(15%)和会聚功能异常(10%)更为常见。

METHODS: A cross-sectional study was conducted among university students who use VDU 3h or more from January 2019 to May 2019. A convenient sampling method was utilized. All subjects had gone through primary eye-examinations to satisfy the inclusion criteria. Those who satisfy the inclusion criteria, further gone through the NSBVA assessment. The descriptive analysis was done to rule out the percentage of NSBVA and Chi-square test of independence was carried out to observe the association of NSBVA with age, gender and hours of VDU usage.

RESULTS: A total of 140 students including 88 females(62.9%)and 52 males(37.1%)participated in this study. The mean age of the participants was 22.54±1.48 years and the mean VDU usage hours were 5.76±2.49h. The percentage of NSBVA is 40% among the students those who use VDU. The occurrence of accommodative and vergence anomalies among the VDU users is 17.86% and 22.14% respectively. There was a moderate association between gender and NSBVA(P=0.010). However, there was no significant association observed for age(P=0.334)and hours of VDU usage(P=0.835)with NSBVA.

CONCLUSION: NSBVA is 40% among the students of a Malaysian private university uses VDU. Accommodation insufficiency(15%)and convergence insufficiency(10%)is more common among all NSBVA for VDU users.
