About this study

CVS-F3 is a valid questionnaire that includes 26 questions to be responded by the medical students to detect CVS complains and possible complications. 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.

Treatment and study plan

CVS Group

Behavioral

the students will respond to CVS-F3 questionnaire to report their potential CVS complains and associated screen factors as screen-time, screen-size, screen-resolution and other factors.

Primary outcomes

  1. Prevalence of CVS

    Time frame: 1 month

    will be reorted in form of percentage (%) of students with CVS

  2. Visual acuity

    Time frame: 1 month

    measurement of visual acuity using distance visual charts in logMAR measurements

  3. Refraction

    Time frame: 1 month

    measurement of refractive power in diopters

  4. Schirmer test

    Time frame: 1 month

    measurement of tear volume production with Schirmer test in mm unit measurements

  5. Tear Break Up Time (TBUT)

    Time frame: 1 month

    measurement of tear film stability with TBUT in seconds time unit measurements

  6. mfERG examinations

    Time frame: 6 months

    mfERG will be performed for the students to document the effect of CVS on retina
