Interleukin 4, IgG and oligoclonal IgG in aqueous humor of cataract patients.

We measured interleukin 4, total IgG, IgG-albumin relative concentration ratio, and oligoclonal IgG in aqueous humors of patients with uncomplicated senile cataracts and cataracts complicated by previous uveitis of unknown etiology. The values of all mentioned parameters are significantly elevated in aqueous humors of patients with complicated cataracts. The possible implications of our findings are briefly discussed.
