Tight Necktie May Boost Glaucoma RiskLashallF
July 28, 2003 — Depending on your tastes, wearing neckties may be an ambush to some folks’ vision. According to a modern think about, wearing them as well tightly may hurt your own.
Researchers say that a too-tight necktie may increment the risk of glaucoma by boosting blood pressure interior the eyes to perilous levels. Particularly, a tight bowtie contracts neck veins and raises the pressure within the eyes. Glaucoma, which torments at least 3 million Americans and is the leading cause of visual impairment in the U.S., more often than not occurs when weight within the eyes increments to dangerous levels.
In their ponder, distributed within the Eminent issue of the British Journal of Ophthalmology, analysts noticed a little but critical increase in this intraocular weight in men who wore tight neckties. The 40 men examined — half of them glaucoma patients and the others with no obvious vision-threatening condition — were observed beneath three scenarios. When their neckties were fixed for three minutes, intraocular pressure spiked in 60% of the glaucoma patients and 70% of the sound men. There were no such increments when they extricated their ties for three minutes or while wearing open-collared shirts.
Does this mean that neckwear will before long join a list of established hazard components for glaucoma that incorporates being more seasoned than age 40; of African-American, Irish, Russian, Japanese, Hispanic, or Scandinavian plummet; or having diabetes, hypertension, poor vision, or a family history of glaucoma?
Maybe not, but it does suggest that when it comes to neckwear, tight isn’t right — at least when it comes to ensuring your vision.
“No one says you’ve got to strangle yourself,” says think about author Robert Ritch, MD, chief of glaucoma administrations and specialist chief at the New York Eye and Ear Clinic. “On the off chance that you can’t get your finger in between your neck and your collar effectively, it’s as well tight.”
Ritch tells WebMD that he conducted the consider with other Unused York researchers because he taken note that in his claim patients — particularly those with thick necks — their intraocular pressure would decrease when he had them extricate their neckties during an eye exam.
“I have been telling my patients for years that on the off chance that they have glaucoma, they should not wear tight neckties.” Still, although eye weight increases can be noted after just a few minutes of a wearing a tight necktie, Ritch says that in all probability, it would have to be compelled to be “visit and delayed” to likely make tight neckwear a real threat to vision.
Other experts not involved in Ritch’s ponder say that whereas it copies what has long been known — that a short-term boost in neck pressure produces a sudden and gentle increment in eye pressure — there’s no reason to believe that neckties can cause glaucoma.
“Since the study endured as it were three minutes, it is inconceivable to know how long it would take to return to the original eye pressure,” says glaucoma pro Harry A. Quigley, MD, of the Wilmer Eye Founded at Johns Hopkins School of Medicine.
“This investigate does not display any real evidence that this calculate increases chance of glaucoma,” he tells WebMD. “It is basically common sense not to wear collars that are so tight that they cut off blood return from the brain. How many men tie their ties to the point of distress and leave them that way for prolonged periods?”
Steven J. Gedde, MD, of Bascom Palmer Eye Organized, lauded the consider — and its research group — for reminding ophthalmologists that a tight necktie may be along the other “outside” factors, such as holding one’s breath or having the hiccups, which can temporarily raise intraocular weight and conceivably produce untrue readings.
“When I degree someone’s intraocular weight, I tell patients not to hold their breath because we know that can cause a (short-term) rise in intraocular pressure. Which might impact how these levels are examined and the chosen course of treatment,” Gedde says. “Wearing a tie seems to drop beneath that same category.”
