The Connection Between Glaucoma and Sleep Apnea

Do you suffer from obstructive sleep apnea (OSA)? Sleep apnea is a sleep disorder in which breathing repeatedly stops and starts while sleeping. OSA symptoms include loud snoring, gasping for air during sleep, feeling sleepy during the day, and waking with a headache. Leaving this condition untreated may lead to serious health problems like stroke, heart attack, or high blood pressure – but it could lead to vision problems with glaucoma.

According to the American Academy of Ophthalmology and the American Optometric Association, glaucoma affects the eye’s optic nerve, and it is called the silent thief of sight because there are no signs of symptoms at first. As the optic nerve becomes damaged, vision is gradually lost and cannot be recovered.

A few studies have shown that patients who suffer from sleep apnea are more likely to develop glaucoma than those who do not have this sleep problem. Recent studies collectively showed that if an individual has OSA, there is an increased risk of glaucoma that ranged from 21% to 450%. They found that patients participating in the studies demonstrated sleep apnea and their eye pressures were lower when their intraocular pressure was measured. All the studies between obstructive sleep apnea and glaucoma came to a similar conclusion. The risk for a person diagnosed with sleep apnea could be as high as ten times more for having the eye condition glaucoma. They concluded studies that the mechanism increased the risk of oxygen deficiency to the optic nerve.

Know the Facts

  • Glaucoma affects 3 million Americans, and it is the second leading cause of blindness worldwide.
  • Many people who have glaucoma have not yet been diagnosed.
  • In 2020, about 80 million people had glaucoma worldwide, which is expected to increase to over 111 million by 2040.
  • Sleep apnea affects 100 million people around the world and 25 million people in America.
  • A blocked airway can cause snoring, gasping, or choking because breathing stops for up to two minutes.
