Obstructive Sleep Apnea Assessed by Overnight Polysomnography in Patients With Keratoconus

Abstract

As measured by overnight home sleep apnea testing, OSA was 10 to 20 times more prevalent among patients with KCN than the rate reported for the general population. The rate lies between the prevalence estimated from sleep study data of self-reported diagnosis of OSA and the risk of developing OSA as determined by the Berlin Questionnaire.
