[Prevalence of sleep-disordered breathing in patients with retinal vein occlusion].
ABSTRACT To investigate the prevalence of sleep-disordered breathing (SDB) in retinal vein occlusion (RVO) patients.
Forty RVO patients who had undergone either vitreous surgery or anti-coagulation therapy were included in this study. Pulse oximetry was conducted during the night and 4% oxygen desaturation index (4% ODI times/hour) and mean SpO2 (%) were calculated. If 4% ODI > or = 5, SDB was diagnosed. The results were compared between branch retinal vein occlusion (BRVO), and central retinal vein occlusion (CRVO). In addition, simple linear regression analyses were conducted to investigate whether 4% ODI related to systemic factors for RVO patients, i.e., incidences of hypertension and diabetes and body mass index(BMI kg/m2).
Forty two percent of the men, 33% of the women and 37% of all the RVO patients were diagnosed as having SDB. The prevalence of SDB and 4% ODI, and the mean SpO2 were not significantly different between the BRVO and CRVO cases. The incidences of diabetes tended to correlate to the 4% ODI, however, neither proved significant. The BMI had a statistic correlation with the 4% ODI.
The results of our study suggested that RVO cases have a high frequency of SDB. We believe that at the time of ophthalmic medical examinations or during the treatment of RVO, ophthalmologists should be aware of the possibility of SDB.
