| Abstract |
The aim of the study was to evaluate the prevalence of serum anti-retinal (ARAs) and anti-endothelial cell antibodies (ACEAs) in patients with acute and chronic central serous chorioretinopathy (CSC). We enrolled 28 patients with acute CSC, 42 patients with chronic CSC, and 40 healthy controls. The presence of ARAs was determined by indirect immunofluorescence using monkey retina as an antigen substrate, while the presence of AECAs was determined using cultivated human umbilical vein endothelial cells (HUVECs) and primate skeletal muscle according to the manufacturer's instructions (Euroimmun AG). There were no differences in the prevalence of antibodies against rods, cones, cytoplasmic components of retinal nuclear layer cells, and retinal vessels between the acute and chronic CSC groups and the control group (P = 0.27, P = 0.16, P = 0.71, and P = 0.06, respectively). However, AECAs reactive with HUVECs were observed in 46% of patients with acute CSC, 45% of those with chronic CSC, and 22% of controls, whereas AECAs reactive with the skeletal muscle were present in 46%, 45%, and 15%, respectively (difference between groups: P = 0.045 for HUVECs and P = 0.005 for the skeletal muscle). Furthermore, AECA titers were higher in CSC patients than in controls (P = 0.004). This study provides evidence for the possible involvement of an autoimmune process directed against vessel antigens in the pathogenesis of CSC. AECAs may be more important than ARAs in this disease and may be involved in endothelial damage in the choroidal vessels and choriocapillaris, leading to hyperpermeability, which is central to the pathophysiology of CSC.
