Summary:To observe the ophthalmic artery (OA), central retinal artery (CRA) and posterior ciliary artery (PCA) blood flow and the changes of eye vascular auto-regulation in patients with obstructive sleep apnea-hypopnea syndrome (OSAS). It was a case-control study. Fifteen health overweight male adult (as normal control) and 42 patients with OSAS were randomly selected from examination center and sleep detection center, respectively. The OSAS patients were divided into mild (14 patients) and moderate and severe (28 patients) groups based on the apnea-hypopnea index (AHI). All subjects filled the sleep questionnaire and carried out polysomnogram monitoring all night for at least 7 hours. Fasting peripheral venous blood was collected at 7 AM on next day. The end-tidal CO(2) (ETCO(2)), intraocular pressure and color doppler sonography were examined next day to record the data in the inspection process before and after Mueller maneuver.
