Obstructive sleep apnea-hypopnea syndrome may have predisposition for evaporative dry eye

Patients with obstructive sleep apnea-hypopnea syndrome may experience damage to the meibomian glands and a shortened first noninvasive tear breakup time, which can lead to a predisposition for evaporative dry eye.
Researchers evaluated the effect of obstructive sleep apnea-hypopnea syndrome (OSAHS) on the meibomian glands, ocular surface and tear parameters in a prospective study of 59 individuals. The study included 32 participants with OSAHS and 27 control subjects.
All subjects underwent polysomnography, and Apnea Hypopnea Index value was recorded. Average noninvasive tear breakup time and
