Dry eye disease (DED) is an ocular disease that affects 5% to 17% of the US population. Because of the negative effects of DED on patients' quality of life (QOL), disease-specific questionnaires that assess QOL in patients with dry eyes are essential in the monitoring and management of this chronic ocular condition. This review provides clinicians and researchers with a summary of the current questionnaires available for assessing QOL in patients with dry eyes.
A systematic review of the literature was performed in March 2013.
There are only 2 validated, reliable dry eye questionnaires with QOL measures currently available for clinic use: the Ocular Surface Disease Index (OSDI) and the Impact of Dry Eye on Everyday Life questionnaire (IDEEL). Multiple other dry eye questionnaires assess some degree of QOL, but they have either not been tested for validity and reliability or are limited in QOL measures they assess.
The OSDI and IDEEL are validated, reliable disease-specific questionnaires that assess QOL measures in patients with DED. Because of its extensive development process and multiple QOL measures, the IDEEL offers a more thorough assessment of the effect of DED on QOL for clinical trials, whereas the OSDI may be the more convenient option for clinical use as a result of its shorter completion time. Other questionnaires used to assess QOL in DED (eg, 25-item National Eye Institute Visual Function Questionnaire and Texas Eye Research and Technology Center DEQ) are fairly limited in this assessment. Finally, because of the negative effects of DED on QOL, this review emphasizes the importance of including QOL measures in future questionnaires for the monitoring and management of DED.
