IgG4-related ophthalmic disease

AbstractIgG4-related disease is a fibro-inflammatory condition with tendency to form tumors with inflammatory infiltrate with IgG4 rich plasma cells and elevation of IgG4 level in serum, which may affect virtually every organ and tissue in the organism. IgG4-related ophthalmic disease may present as dacryoadenitis, myositis, other orbital tissues, hypophysitis or pachymeningitis causing cranial neuropathies. The diagnosis of IgG4-related disease is based on a typical clinical scenario, supportive laboratory data, expected radiological characteristics and distinct histopathological and immunohistochemical features. Corticosteroid followed by the use of long-term immunosuppressive therapy is the most commonly attempted treatment
