Obstructive Sleep Apnea, Retinal Vein Occlusion, Retinal Artery Occlusion

January 31, 2012 updated by: Yonsei University
Obstructive sleep apnea is a common disorder linked to serious long-term adverse health consequences; such as hypertension, metabolic dysfunction, cardiovascular disease. Retinal vascular occlusion is related to many systemic illnesses especially hypertension. Obstructive sleep apnea is also related to vascular endothelial dysfunction and vascular endothelial growth factor elevation which causes vision threatening complications of retinal vascular occlusion. Therefore the relationship between obstructive sleep apnea and retinal vascular occlusion should be studied.
