Analysis of Autoantibodies Against Human Retinal Antigens in Sera of Patients with Glaucoma and Ocular Hypertension

The aim of this study was to show that complex antibody patterns against retinal antigens in sera of patients with glaucoma, found in previous studies, are autoantibodies against human antigens.Sera of 179 patients were collected at the Department of Ophthalmology (University of Mainz, Germany): non-glaucomatous control patients (n=45), primary open-angle glaucoma (n=45), ocular hypertension (n=44), and normal tension glaucoma patients (n=45). The sera were tested against Western blots of human retinal antigens. IgG antibody patterns were analyzed by multivariate statistical techniques, and some significant antigens were identified by mass spectrometry.All subjects, even healthy ones, showe…
