Key result
Sleep-disordered breathing was significantly associated with an increased risk of retinal vein occlusion in adults (RR 1.92; 95% CI 1.60-2.30; P < .001).
Why the study?
Previous studies suggested that sleep-disordered breathing may be a potential risk factor for retinal vein occlusion, motivating a meta-analysis to systematically explore this relationship.

Sleep-disordered breathing is significantly associated with an increased risk of retinal vein occlusion, highlighting the potential importance of screening for SDB in these patients.
BACKGROUND: Previous studies suggest that sleep-disordered breathing (SDB) may be a potential risk factor of retinal vein occlusion (RVO). We conducted a meta-analysis to systematically explore the relationship between RVO and SDB. METHODS: Observational studies assessing the relationship between SDB and RVO were retrieved by searches of electronic databases including the PubMed, Embase, Web of Science, China National Knowledge Infrastructure, and Wan Fang databases from database inception to August 9, 2023. In consideration of intra-study heterogeneity, a random-effects model was adopted to combine the results. RESULTS: Seven studies (1 retrospective cohort and 6 case-control studies) were included in this meta-analysis, and among 36,628 adults included in those studies, 6452 (17.6%) had SDB. The combined results indicated that SDB was associated with RVO [risk ratio (RR): 1.92, 95% confidence interval (CI): 1.60-2.30, P < .001] with no significant heterogeneity (I2 = 0%). Subgroup analyses showed consistent relationships between SDB and any RVO (RR: 1.73, 95% CI: 1.13-2.28, P < .001), central RVO (RR: 2.20, 95% CI: 1.57-3.08, P < .001), and branch RVO (RR: 1.85, 95% CI: 1.15-2.99, P = .01). Moreover, the relationship was consistent among patients with mild (RR: 1.82, 95% CI: 1.32-2.53, P < .001), moderate (RR: 2.17, 95% CI: 1.65-2.85, P < .001), and severe SDB (RR: 2.66, 95% CI: 1.96-3.62, P < .001). The association was consistent in studies that adjusted for age and sex (RR: 2.17, 95% CI: 1.50-3.13, P < .001), and in studies with additional adjustment for comorbidities (RR: 1.78, 95% CI: 1.42-2.25, P < .001). CONCLUSION: SDB is associated with RVO in adults.

Zhang et al. (2023) conducted a meta-analysis in Retinal vein occlusion (n=36,628). Sleep-disordered breathing vs. No sleep-disordered breathing was evaluated on Retinal vein occlusion (RR 1.92, 95% CI 1.60-2.30, p=< .001). Sleep-disordered breathing was significantly associated with an increased risk of retinal vein occlusion in adults (RR 1.92; 95% CI 1.60-2.30; P < .001).
