There was no convincing evidence that obstructive sleep apnoea was associated with diabetic retinopathy, although some evidence suggested that obstructive sleep apnoea was associated with greater severity of diabetic retinopathy and advanced diabetic retinopathy in people with Type 2 diabetes. Only six studies examined the impact of obstructive sleep apnoea on diabetic maculopathy and our narrative review suggests there is an association in Type 2 diabetes. Oxygen desaturation index, mean oxygen saturation or time spent with\u00a0&lt;\u00a090% oxygen saturation were not associated with diabetic retinopathy, and insufficient evidence was available to draw conclusions on their effects on diabetic maculopathy; however, there was evidence from both narrative synthesis and meta\u2010analysis that minimum oxygen saturation had an impact on diabetic retinopathy (pooled odds ratio 0.91, 95% <jats:styled-content style=\"fixed-case\">CI<\/jats:styled-content> 0.87\u20130.95; I<jats:sup>2<\/jats:sup>\u00a0=\u00a00%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>There is a need for large cohort studies with long\u2010term follow\u2010up data to examine the long\u2010term effects of obstructive sleep apnoea and other sleep variables on advanced retinal disease in diabetes.<\/jats:p><\/jats:sec>","DOI":"10.1111\/dme.12817","type":"journal-article","created":{"date-parts":[[2015,5,29]],"date-time":"2015-05-29T18:24:45Z","timestamp":1432923885000},"page":"158-168","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":64,"title":["Effect of obstructive sleep apnoea on diabetic retinopathy and maculopathy: a systematic review and meta\u2010analysis"],"prefix":"10.1111","volume":"33","author":[{"given":"W.
