A Field Test of Web-Based Screening for Dry Eye Disease to Enhance Awareness of Eye Problems Among General Internet Users: A Latent Strategy to Promote Health

Abstract

BackgroundA Web-based self-check system including a brief questionnaire would seem to be a suitable tool for rapid disease screening.ObjectiveThe purpose of this preliminary study was to test a Web-based self-screening questionnaire for drawing attention to dry eye disease among general Internet users and identifying those with a higher risk of developing the condition.MethodsA survey website was launched and used to recruit participants from general Internet users. In the first phase, volunteers were asked to complete a Web-based self-screening questionnaire containing 12 questions on dry eye symptoms. The second phase focused on the respondents who reported five or more dry eye symptoms and expressed their intention to seek medical attention. These participants performed the Schirmer test, for evaluating tear production, and completed a paper-based lifestyle questionnaire to provide relevant background data.ResultsOf the 1689 visitors to the website, 980 (58.0%) volunteers completed the Web-based self-screening questionnaire. Among these, 355 (36.2%) respondents reported five or more dry eye symptoms. Then, 99 (27.9%) of the symptomatic participants performed the Schirmer test and completed the paper-based lifestyle questionnaire. Out of these, 32 (32.2%) had abnormal tear production (≤5 mm).ConclusionsThe proposed Web-based self-screening questionnaire seems to be a promising tool for raising awareness of dry eye disease among general Internet users and identifying those with a higher risk of developing the condition, although further research is needed to validate its effectiveness.

The Association between Dry Eye Disease and Physical Activity as well as Sedentary Behavior: Results from the Osaka Study

“…Ocular symptoms such as eye dryness, eye strain, and blurry vision are symptoms commonly reported by VDT users [ 22 ]. A large-scale epidemiologic study amongst office workers in Japan recently showed that VDT work is an important risk factor for DED [ 9 ].…”

The association of sleep quality with dry eye disease: the Osaka study

“…Ocular symptoms such as dryness, eyestrains, and blurry vision are commonly reported symptoms related to visual display terminal (VDT) users. 10 VDT exposure has been increasing among office workers because of the rapid advancement of information technology. A recent large-scale epidemiologic study of office workers in Japan concluded that VDT work is considered one of the key risk factors for DED.…”

Prevalence of Dry Eye Disease in a Rural Niger Delta Community, Southern Nigeria

“…In a web-based screening for DED study carried out on 1689 computer users aged 20 years and above, 36.2% of participants reported 5 or more dry eye symptoms. The participants that had symptoms of dry eye were investigated with schirmer test and 32.2% of them had abnormal tear production [20].…”

“…In 2003, in the United States of America, a population-based survey on prevalence of dry eye among mid-aged and above, 39,876 women participating in the Women's Health Study showed the prevalence of DED to be 5.7% among women less than 50 years old and 7.8% among women greater than 50 years [20].…”
