Abstract

Introduction:
Sleep apnea syndrome (SAS) is a known disease involving intermittent hypoxia (IH), recurrent symptoms of deoxygenation while sleeping, long daytime sleepiness, and significant loss of quality of life. In-laboratory polysomnography is marked as the gold standard for diagnosis of clinically suspected sleep-related breathing disorders in adults. A home sleep test is an alternative diagnostic method for patients with no major comorbid conditions. Obstructive sleep apnea is characterized by episodic sleep state– dependent collapse of the upper airway, resulting in periodic reductions or cessations in ventilation, with consequent hypoxia, hypercapnia, or arousals from sleep. Obstructive sleep apnea (OSA) is very common but unfortunately frequently undiagnosed. Motor vehicle accidents due to drowsy driving are a particular concern. Evaluation and treatment should focus on symptomatic patients, both to alleviate symptoms and to potentially decrease cardiovascular risk. Among the symptoms include loud snoring, nocturnal awakening, and daytime sleepiness. Keratoconus is one of corneal ectatic disorders characterized by a progressive thinning into a conical shape leading to a progressive loss of vision.
Aim of the work: The aim of this work was to study the prevalence of floppy eyelid and keratoconus in patient with obstructive sleep apnea syndrome.
