According to New Study, Migraine Raises Risk of Chronic Dry Eye Disease

For men, aged 65 or above, having migraine nearly doubled the odds of dry eye disease, and risk in women of the same age was almost 2.5 times

Suffering from migraine? You could be at higher odds of having chronic dry eye disease, says a new study.

The chronic dry eye is a common disease in which natural tears fail to adequately lubricate the eyes, thus affecting its functioning and lessening a person’s quality of life.

The study showed that people with migraine had a 20 per cent higher risk of having dry eye disease, the HealthDay reported.

For men, aged 65 or above, having migraine nearly doubled the odds of dry eye disease, and risk in women of the same age was almost 2.5 times.

The association between migraine and dry eye was found to be more among the elderly, particularly for women due to hormonal changes caused by pregnancy, the use of oral contraceptives and menopause, the researchers said.

“Physicians caring for patients with a history of migraine headaches should be aware that these patients may be at risk for concurrent dry eye disease,” said Richard Davis, ophthalmologist at the University of North Carolina at Chapel Hill in the US.

For the study, the team examined 73,000 adults.

The findings, published in the journal JAMA Ophthalmology, showed 8-34 per cent of adults may be affected by dry eye disease.

Further, similar underlying inflammatory processes at the cellular level are known to play key roles in both dry eye disease and migraine.

“Inflammatory changes in dry eye disease might trigger similar events in neuromuscular tissue, leading to the development and propagation of migraine headaches,” the team noted.

In addition, rheumatoid arthritis, diabetes, thyroid problems, exposure to smoke, wind and dry climates, and long-term use of contact lenses can also lead to dry eyes, the study noted. (IANS)

Migraine With Visual Aura May Increase Risk of Irregular Heartbeat

People who experience migraine with visual aura may have an increased risk of irregular heartbeat, and as a result stroke, say researchers including one of an Indian-origin.

Migraine with visual aura is when disturbances in vision occur right before the head pain begins. Those disturbances may include seeing wavy lines or flashes of light, or having blurry vision or blind spots.

With an irregular heartbeat called atrial fibrillation, the heart’s normal rhythm is out of sync. As a result, blood may pool in the heart, possibly forming clots that may go to the brain, causing a stroke.

The study suggested that atrial fibrillation may play a role in stroke in those with migraine with visual aura.

“It is important to note that people with migraine with aura may be at a higher risk of atrial fibrillation due to problems with the autonomic nervous system, which helps control the heart and blood vessels,” said Souvik Sen, from the University of South Carolina in the US.

The study suggested that atrial fibrillation may play a role in stroke in those with migraine with visual aura.

For the study, published in the journal, Neurology, the team examined 11,939 people with an average age of 60 without prior atrial fibrillation or stroke were evaluated for headache.

The results revealed an estimated nine out of 1,000 people with migraine with aura suffer atrial fibrillation compared to seven out of 1,000 people with migraine without aura.

The rate of stroke in the migraine with aura group was four out of 1,000 people annually compared to two out of 1,000 people annually in those with migraine without aura, and three of 1,000 people annually in those with no headache, the findings suggested.
