Prevalence and Sequelae of Computer Vision Syndrome in Egyptian Universities

Visual, Ocular Surface and Extraocular Diagnostic Criteria for Prevalence of Computer Vision Syndrome: A Cross-sectional Smart-survey Based Study

CVS-F4 questionnaire will be used as an instrument to survey CVS prevalence and severity among medical students

CVS-F4 (30 questions) will be an online survey via the SurveyMonkey Company. We will collect the responses and analyze the results. Informed consent will be obtained from the participants as an item within the survey itself that he/she agrees to use his/her data in this research work. The questionnaire includes questions regarding potential ocular, extra-ocular, musclo-skeletal and neuro-psychatric complains caused by CVS. Complete statistical analysis of the survey data will be done using univariate and multivariate logistic and linear regression analysis. The CVS diagnosis will be based on the 5 diagnostic criteria (5DC) to create a new short self-assessment questionnaire for accurate prevalence of CVS.
