To evaluate functional vision, general health status, and work productivity in individuals with and without dry eye disease (DED).
Cross-sectional study.
SettingGeneral US population (2018).
Adults ≥18 years with (n = 1003) or without (n = 1006) self-reported DED.
All respondents completed the National Eye Institute Visual Function Questionnaire (VFQ) and the EuroQol 5-dimensions 5-levels (EQ-5D-5L). All respondents with DED completed the eye dryness score (EDS) visual analogue scale, Ocular Comfort Index (OCI), and Work Productivity and Activity Impairment (WPAI) questionnaire. Half of respondents with DED completed the Impact of Dry Eye on Everyday Life (IDEEL) questionnaire; the other half completed the Dry Eye Questionnaire 5 (DEQ-5) and Standardized Patient Evaluation of Eye Dryness (SPEED), McMonnies, and Symptom Assessment in Dry Eye (SANDE) questionnaires. All analyses were descriptive.
Respondents with DED reported more comorbidities, greater exposure to adverse environmental conditions, and lower (worse) mean (standard deviation) scores on the modified Rasch-scored 28-item VFQ (VFQ-28R) total score (68.8 [11.9] vs 81.2 [12.7]) and EQ-5D-5L (0.82 [0.13] vs 0.88 [0.14]) than respondents without DED. Respondents with DED and EDS≥60 (highest discomfort) fared worse on OCI, VFQ-28R, and WPAI than respondents with DED and EDS<40 (lowest discomfort). Similar findings were observed with IDEEL, DEQ-5, SPEED, McMonnies, and SANDE scores.
There is a substantial burden of DED on functional vision, general health status, and productivity and further, these parameters appear to worsen with increasing EDS.
