比較患有電腦視覺症候群的年輕族群之乾眼狀況與視覺功能相關表現
Comparing Dry Eye Symptoms and Visual Functions in Young Population with Computer Vision Syndrome
摘要
目的： 隨著科技發展，具有視覺顯示終端（VDT）的計算設備已充斥人們之生活。然而，長期近距離觀看這些VDT可能帶來相關健康危害。因此，此研究欲透過電腦視覺症候群問卷（CVS-Q）評估當前患有電腦視覺症候群（CVS）年輕族群之乾眼情形與雙眼視覺功能相關表現，以及其他問卷之表現，並探討相關主客觀數值。 方法： 本研究的實驗流程。主要分為兩階段：第一階段為請研究對象先填寫電腦視覺症候群問卷（CVS-Q）和使用VDT之習慣調查問卷；第二階段進行檢查及其他問卷填寫。檢查項目包括雙眼視功能及乾眼症狀，雙眼視功能的檢查包括：遠方與近方眼位檢測、調節幅度、調節靈敏度、聚散能力檢測等；乾眼症狀的檢查則包括：淚膜破裂時間及淚液量。而問卷包括：電腦視覺症狀量表（CVSS17）、5項乾眼問卷（DEQ-5）、眼表疾病指數（OSDI）。 結果： 本研究所測得之CVS發生率為54%。在雙眼視檢查中，僅在調節靈敏度發現顯著差異。關於淚膜測試，Schirmer test和TBUT都具有顯著差異。關於其他問卷調查，包含CVSS17、DEQ-5、OSDI等三份問卷，在本研究中僅在CVSS17和OSDI中發現顯著差異。在生活習慣之調查中，VDT的每日使用時間和VDT的使用距離發現顯著差異。 結論： 本研究調查之雙眼視功能大多沒有顯著差異，而淚膜測試則皆有顯著差異。推測CVS影響眼表和眨眼頻率較多，使乾眼症狀增多。而與乾眼或CVS相關之問卷則能快速且高效的判斷主觀症狀，仍推薦使用。除此之外也呼籲，人們在使用VDT時應檢查環境及VDT之亮度，確保休息時間，合理分配每日使用VDT之時間，且維持良好姿勢及妥當距離。

Purpose With the advancement of technology, visual display terminal (VDT) devices have become ubiquitous in people's lives. However, prolonged close-range viewing of these VDTs may lead to associated health risks. Therefore, this study aims to evaluate the dry eye condition and binocular visual function performance in young individuals with computer vision syndrome (CVS) using the Computer Vision Syndrome Questionnaire (CVS-Q), as well as assess other related symptoms through various questionnaires, and to explore the relevant subjective and objective measurements. Methods The experimental procedure of this study is divided into two main stages. The first stage involves having participants complete the Computer Vision Syndrome Questionnaire (CVS-Q) and a survey on their VDT usage habits. The second stage includes examinations and additional questionnaire completions. The examinations cover binocular visual function and dry eye symptoms. Binocular visual function tests include: distance and near phoria tests, amplitude of accommodation, accommodative facility, and convergence ability tests. Dry eye symptoms are evaluated using tests such as tear film breakup time (TBUT) and Schirmer test. The questionnaires include: Computer Vision Symptom Scale (CVSS17), 5-Item Dry Eye Questionnaire (DEQ-5), and Ocular Surface Disease Index (OSDI). Results The prevalence rate of CVS measured in this study was 54%. Among the binocular vision tests, significant differences were found only in accommodative facility. For tear film tests, significant differences were observed in both the Schirmer test and TBUT. Regarding other questionnaires, significant differences were found in CVSS17 and OSDI, but not in DEQ-5. In the lifestyle survey, significant differences were found in the daily usage time and usage distance of VDTs. Discussion This study found that most binocular visual function tests did not show significant differences, while all tear film tests showed significant differences. It is suggested that CVS affects the ocular surface and blink frequency more, increasing dry eye symptoms. Questionnaires related to dry eye or CVS can quickly and efficiently assess subjective symptoms and are recommended for use. Additionally, it is advised that individuals check their environment and VDT brightness, ensure adequate rest periods, reasonably allocate daily VDT usage time, and maintain good posture and appropriate distance when using VDTs.
