Abstract
Using isoelectric focusing (IEF) and immunoperoxidase staining of proteins transferred to nitrocellulose membranes, we have examined the IgG band pattern in tears and matched serum and CSF specimens of 28 patients with MS, 4 patients with optic neuritis (ON), 30 individuals with systemic, inflammatory, or other neurologic diseases, and 5 patients with tension headache. We found no evidence of positive oligoclonal IgG in tears in any MS or ON patients, while 10 out of 16 cases with systemic immune disorders or infections of the CNS had positive tear oligoclonal bands. We are thus not able to support the hypothesis that tears from MS patients reveal abnormalities in their humoral immune response.
