Additionally, individuals with sleep apnea are at a tenfold increased risk of developing glaucoma. This is thought to be due to the lack of oxygen during episodes of breath cessation, which gradually causes the optic nerve tissue to die. In these cases, eye pressure may not rise like it does in most glaucoma patients. Although many people with sleep apnea snore loudly, not everyone who snores has sleep apnea. Therefore, if someone snores loudly and experiences other symptoms such as:

1. Choking
2. Shallow or labored breathing while asleep
3. Brief or prolonged periods of breath cessation
4. Restless or excessive movement during sleep
5. Waking up with headaches
6. Daytime drowsiness
