Obstructive Sleep Apnea in Patients with Central Serous Chorioretinopathy.

Patients with central serous chorioretinopathy (CSC) show an increased sympathetic activity compared to controls. Additionally, there are several reports of increased corticosteroid and catecholamine levels in these patients. Obstructive sleep apnea syndrome (OSAS) has been shown to enhance sympathetic activity depending on severity. Respiratory disturbance increases urinary catecholamine secretion and is associated with the occurance of hypertension in a dose dependent manner. Therefore we hypothesize that OSAS may act as a risk factor for the development of CSC.
