Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS) is a condition characterized by episodes of apnea and hypopnea during sleep, with sleep snoring being the primary symptom. The association between OSAHS and ophthalmic diseases has long been recognized, and the potential pathogenic mechanisms have been widely investigated in recent years. It is currently believed that the alteration of inflammatory factors caused by OSAHS plays a key role, affecting vascular function and ultimately leading to the occurrence of diseases. Numerous studies have found a close relationship between OSAHS and the development of fundus diseases. Further research into the pathogenesis of OSAHS is needed in the future to enrich the conclusions regarding the relationship between OSAHS and eye diseases, with the aim of achieving prevention, treatment, and favorable prognosis for related eye conditions.
