Association of obstructive sleep apnea and continuous positive airway pressure on risk of corneal ulceration and surgical interventions.

Obstructive sleep apnea was associated with higher incidence of corneal ulceration, severe ulcer-related sequelae, and corneal surgical interventions.

continuous positive airway pressure was associated with fewer severe ulcer complications and reduced keratoplasty utilization, but higher dry eye burden.

continuous positive airway pressure was associated with reduced but persistent ocular risk in patients with obstructive sleep apnea.
