Antiretinal antibodies in central serous chorioretinopathy: prevalence and clinical implications
Purpose: To investigate the possible role of autoimmune reactions directed against retinal tissue in central serous chorioretinopathy (CSC), by analysing the presence of serum antiretinal antibodies (ARAs) and establishing their clinical relevance. Methods: Sixty-three patients with CSC were included, and clinical characteristics were collected. Serum samples of all patients with CSC, 101 uveitis patients and 60 healthy donors were analysed for the presence of ARAs by indirect immunofluorescence. Furthermore, all CSC serum samples were analysed on Western blot. Correlations between laboratory findings and clinical features of CSC were determined by logistic regression. Results: Antiretinal antibodies (ARAs) were present in 54% of the patients with CSC, in 46% of uveitis patients (p = 0.153) and in 17% of healthy controls (p < 0.001). The majority of ARAs in CSC were directed against photoreceptors (27%), which occurred significantly more often compared to uveitis patients (15%, p = 0.039) and to healthy controls (5%, p = 0.003). No associations between clinical CSC characteristics and the presence of ARAs were found. Conclusion: Serum ARAs are present in more than half of the patients with CSC, and especially, ARAs directed against photoreceptors were detected more frequently compared to both healthy controls and uveitis patients. Further research is warranted to unravel the role of ARAs in the pathogenesis of CSC.
