PURPOSE: To report three cases of nonarteritic anterior ischemic optic neuropathy (NAION) that occurred in patients with sleep apnea syndrome (SAS) while being treated with continuous positive airway pressure (CPAP).
DESIGN: 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 treatment with CPAP for SAS. All the patients were being treated with CPAP for a period ranging from 4 months to 6 years before the onset of NAION.
CONCLUSIONS: In this series, CPAP did not prevent the development of NAION in SAS patients. Largerobservational studies are needed to study the benefit of CPAP in preventing NAION in patients with SAS.
