Current Estimates Uncertain on the Prevalence of Dry Eye in United States

A recent systematic review and meta-analysis reported uncertainty on the estimates of the prevalence of dry eye disease (DED) and meibomian gland dysfunction (MGD) in the United States population. Investigators at the University of Colorado Anschutz noted this wide range of prevalence – from 5.3% to 14.5% – estimates for dry eye reflected the notable clinical and methodological heterogeneity across studies.
