Ocular myasthenia gravis (OMG) is an autoimmune neuromuscular disease mediated by pathogenic autoantibodies. Its etiology and pathogenesis are not completely clear. The occurrence and development of OMG are the result of the joint participation of genetic factors, environmental factors and immune factors. The role of infectious factors in the pathogenesis of autoimmune diseases is a hot topic in the international discussion.By analyzing the difference in the positive rate and titer of CMV antibodies between ocular myasthenia gravis and healthy people. By analyzing the correlation between the positive rate and titer of CMV antibodies and ocular myasthenia gravis clinical manifestations, acetylcholine receptor antibodies, ESR, hypersensitive C-reactive protein, complement C3, complement C4 and thymus status.To investigate the correlation between cytomegalovirus and ocular myasthenia gravis. It can provide new insights for further studies on the etiology and possible pathogenesis of ocular myasthenia gravis.
