Study explores link between sleep duration and major eye disorders
There may be a possible link before the risk of developing a major eye disorder, including myopia, glaucoma, cataract, age-related macular degeneration (AMD), and diabetic retinopathy (DR), and circadian rhythms, according to a study that evaluated sleep duration and risk of eye disorder.
Researchers identified 21 articles (n =17 cross-sectional, n = 3 longitudinal, n= 1 was case-control) assessing the relationship between sleep duration and major eye disorders, including 777,348 participants.
When results were pooled, long sleep duration was significantly associated with the risk of DR whereas and short sleep duration was significantly associated with the risk of cataracts. There was a significant relationship found between the risk of DR and long sleep duration each day, which included sleeping at night in addition to naps during the day compared with sleep duration at night. If an individual slept >10 h per night, an increased risk of myopia was observed.
“Inappropriate sleep duration might increase the risk of major eye disorders. The findings could contribute to the growing knowledge on the possible relationship between circadian rhythms and eye disorders,” the authors concluded.
