Background Many individuals with migraine report symptoms of dry eye (DE). However, it is not known whether DE profiles are similar between individuals with and without migraine. To bridge this gap, we evaluated symptoms and signs of DE, including symptoms suggestive of nerve dysfunction, in a large group of individuals with DE symptoms, and compared profiles between individuals with migraine and those without migraine or headache.
Methods Prospective cross-sectional study of individuals with DE symptoms seen at the Miami VA.
Results Of 250 individuals, 31 met International Classification of Headache Disorders criteria for migraine based on a validated screen. Individuals with migraine were significantly younger (57 vs 62 years) and more likely to be female (26% vs 6%) than controls. Individuals with migraine had more severe DE symptoms and ocular pain compared with controls (mean Ocular Surface Disease Index 53.93 ± 21.76 vs 36.30 ± 22.90, p=0.0001; mean Neuropathic Pain Symptom Inventory modified for the Eye 39.39 ± 23.33 vs 21.86 ± 20.17, p=0.0001). The difference in symptom profile occurred despite similar ocular surface parameters between the groups.
Conclusions Individuals with migraine had a different DE symptom yet a similar DE sign profile when compared with controls without migraine. This suggests that DE symptoms in individuals with migraine may be driven by nerve dysfunction as opposed to ocular surface abnormalities.
