Study Details

Study Description

Brief Summary

the university students will respond to CVS-F3 survey form and then they will be subjected to complete ophthalmic examination and investigations

Condition or Disease Intervention/Treatment Phase
  • Diagnostic Test: mfERG (multifocal-retinogram)
N/A

Detailed Description

CVS-F3 is a survey form consisted of up to 30 questions regarding Computer Vision Syndrome (CVS) complains, thereafter a randomized sample of students will be subjected to complete ophthalmic examination including visual acuity and refractive measurements, intraocular pressure measurements, Slitlamp and fungus examinations, mfERG examinations. the sudents will be requested to decrease their screen time and the examinations will be repeated one month later.

Arms and Interventions

Arm Intervention/Treatment
Placebo Comparator: Non-complaining group

the students in this group are not complaining of CVS symptoms but will be examined to diagnose CVS or exclude it

Diagnostic Test: mfERG (multifocal-retinogram)
mfERG will be performed for the students to document the effect of CVS on retina

Experimental: Complaining group

the students in this group are complaining of CVS symptoms but will be examined to document their complains and correlate to clinical findings

Diagnostic Test: mfERG (multifocal-retinogram)
mfERG will be performed for the students to document the effect of CVS on retina

Outcome Measures

Primary Outcome Measures

  1. visual acuity [1 month]

    visual changes i.e. uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA) using logMAR measurements following reduction of screen time

  2. near vision [1 month]

    near vision changes following reduction of screen hours using card test, near visual acuity chart and near point test while the measurements will be diopters and lines of near chart
