DESI- GN: A prospective, noncomparative case series. METHODS: Prospective review of 108 patients with NAION diagnosed between 2002 and 2003 to identify any patients who developed NAION while being treated for SAS with CPAP. RESULTS: One patient had bilateral sequential NAION and two patients had unilateral NAION despite tr eatment with CPAP for SAS. All the patients were being treated with CPAP for a p eriod ranging from 4 months to 6 years before the onset of NAION. CONCLUSIONS: I n this series, CPAP did not prevent the development of NAION in SAS patients. Larger observational studies are needed to study the benefit of CPAP in preven ting NAION in patients with SAS.展开更多
