Brief Summary

Video display terminal users frequently refer computer-related visual and ocular symptoms, that are the most frequently occurring health problems among such these subjects. The Italian law has established an eye examination to assess ocular status (D.Lgs 81/08 ex law 626/96) in VDT workers: subjects are evaluated by clinical signs and symptoms. The availability of a validated questionnaire could be very useful to diagnose visual disturbances and to follow them during follow-up examinations in 2014, a Spanish group has developed and validated a questionnaire for the assessment of visual and ocular symptoms in VDT workers. Aim of the present study is to make available to Italian health professionals a new instrument to assess asthenopic symptoms, taking into account the patient's perspective.

Conditions

Video Display Terminal Workers; Computer Vision Syndrome

Outcome Measures

Primary Outcomes (1)

• To assess reliability (Cronbach alpha) of the CVSS

  Cronbach alpha

  one year

Secondary Outcomes (1)

• To assess: -item internal consistency -equality of item-scale correlations -item discriminant validity -temporal stability -discriminating ability (between VDT and non-VDT workers) -external validity

  one year

Study Arms (1)

completion of the computer vision symptom scale questionnaire, italian version

OTHER

video display terminal (VDT) workers completed the questionnaire

Diagnostic Test: computer vision symptom scale (CVSS) questionnaire

Interventions

computer vision symptom scale (CVSS) questionnaire DIAGNOSTIC_TEST

Subjects working at VDT for \>20 hours a week and accessing to the Eye Clinic in order to complete an ocular examination and subjects working at the Foundation accessing to the Eye Clinic in order to complete an ocular status evaluation according to Italian Law 81/08 will be asked to self-complete the questionnaire in presence of the attending junior ophthalmologists prior to the visit with the Ophthalmologist, to avoid interference with visit results (communication of bad/good news)
