Abstract
PURPOSE: To evaluate the association between obstructive sleep apnea and diabetic macular edema (DME) in patients with Type II diabetes, using the apnea-hypopnea index and other nocturnal hypoxemia parameters.
METHODS: This cross-sectional, case-control study included 99 patients with Type II diabetes: the first group included patients with DME (DME+ group) and the second patients without DME (DME- group). Polysomnography was performed in all patients. The two groups were compared, and the risk factors were studied using logistic regression.
RESULTS: The DME+ group comprised 38 patients, and the DME- group comprised 61 patients, aged a mean 68.8 years and 66.3 years (P = 0.27), respectively; mean body mass index was 29.7 and 30.9 (P = 0.16), respectively. The mean apnea-hypopnea index was significantly higher in the DME+ group (43.95 [13.5-87.3]) than in the DME- group (35.18 [3.55-90.7]) (P = 0.034). Patients with DME had more severe obstructive sleep apnea (apnea-hypopnea index >30) than the others: 71% versus 50.8% (P = 0.049). Cumulative time of SPO2 below 90% (CT90%) was independently associated with DME after adjusting for confounding factors, whereas there was no difference between the oxygen desaturation index and minimum O2 saturation.
CONCLUSION: Severe obstructive sleep apnea (apnea-hypopnea index >30) and parameters of nocturnal hypoxemia (cumulative time of SPO2 below 90%) are associated with DME.
