Headaches may be independent risk factor for dry eye disease
Headaches, especially migraines, are related to a higher risk of dry eye disease, according to results of a meta-analysis covering more than 3.5 million individuals.
The analysis included 1 cohort study, 4 case-control studies, and 6 cross-sectional studies covering 3,575,957 individuals. Pooled analysis showed that all-cause headache was related to a higher risk of dry eye disease.
A higher risk of dry eye disease was noted with migraine headaches, tension headaches, and cluster headaches.
The authors concluded that “These results suggest that headaches should be regarded as an independent risk factor for dry eye.”
