Sleep apnea

People with obstructive sleep apnea syndrome are prone to suffer from glaucoma at rate about 10 times higher. Study found optic nerve could be damaged due to hypoxia without a spike in eye pressure. Glaucoma is thought to be a disease in which the optic nerve sustains damage due to increased eye pressure, resulting in restricted visual field. “However, it has been technically difficult to measure eye pressure. We employed a special sensor akin to a contact lens to monitor pressure changes when OSAS patients’ breathing repeatedly stopped during sleep,” said Yasuhiro Shinmei, Hokkaido University.
