Abstract: Obstructive sleep apnea (OSA) is a chronic sleep-related breathing disorder,which can lead to a series of local and systemic complications. The effects of OSA on fundus structure and retinal microcirculation in children include increased intraocular pressure, thinner choroidal thickness, and decreased retinal microvascular density.After adenotonsillectomy, the intraocular pressure of children with OSA decreased and the thickness of retinal nerve fiber layer increased compared with that before surgery.

Key words: Children, Obstructive sleep apnea, Retinal microcirculation
