Obstructive sleep apnoea prevalence in non-arteritic anterior ischaemic optic neuropathy: A response

摘要

We have found similar evidence of obstructive sleep apnoea syndrome (SAS) tested by overnight pulse oximetry in a cohort of 17 consecutive patients presenting to the eye clinic with non-arteritic ischaemic optic neuropathy (NAION). Patients answered an abbreviated questionnaire of SAS and were sent for sleep studies if they had symptoms. They were tested by the sleep clinic with overnight oximetry and answered the Epworth sleepiness scale. Of the patients 64.7% were diagnosed with SAS, 55% were men, and the mean age was 79 years. The prevalence of SAS in patients with NAION has been previously found to be as high as 89%. SAS is also associated with other ophthalmic conditions such as normal tension glaucoma, diabetic maculopathy and central serous choriore-tinopathy. It is becoming an important comorbidity to think about in the eye clinic.
