It is postulated that idiopathic central serous chorioretinopathy (ICSC) may be induced by a variety of underlying choroidal diseases capable of producing initially alterations in the permeability of the choriocapillaries. A history of unusual emotional stress frequently accompanies the onset of visual complaints. We have reported that alterations of serum lipids may exert a powerful effect on tissue plasminogen activator (t-PA) levels acting as a risk factor of variable cardioangiopathies. In this study, we evaluated the levels of t-PA activity, t-PA antigen and plasminogen activator inhibitor-1 (PAI-1) in blood from the patients with central serous chorioretinopathy, and compared them with the levels of total cholesterols (TCH), triglycerides (TG), and high-density lipoprotein cholesterol (HDL). t-PA activity levels and HDL were lower than in standard controls but t-PA antigen, PAI-1 antigen, and TG were higher. These facts may be associated with the pathogenesis or pathophysiological features of ICSC.
