TUESDAY, March 12, 2019 (HealthDay News) — Patients with migraine headache may have increased odds of dry eye disease (DED), according to a study published online March 7 in JAMA Ophthalmology<\/i>.<\/p>\n
Omar M. Ismail, from the University of North Carolina in Chapel Hill, and colleagues conducted a retrospective case-control study involving 72,969 patients older than 18 years to determine the strength of the association between DED and migraine headaches.<\/p>\n
Of the patients, 7.3 percent had a diagnosis of migraine headache and 13.2 percent had a diagnosis of DED. The researchers found that the odds of having DED were 1.72 times higher for those with a diagnosis of migraine headaches versus those without migraine headaches. The odds of having DED was 1.42 times higher given a diagnosis of migraine headaches than that of patients without migraine headaches after accounting for multiple confounding factors.<\/p>\n
“The exact mechanism underlying the relationship between migraine headaches and DED is unclear. However, it is well established that underlying inflammatory processes play a significant role in the pathogenesis of both disorders,” the authors write. “Physicians caring for patients with a history of migraine headaches should be aware that these patients may be at risk for comorbid DED.”<\/p>\n
