In intraocular parasitosis the immunologic reactions in the vitrectomy-fluids depend on the parasitic agent: there is a lymphocytical reaction without any IgE production in toxoplasmic chorioretinitis, whereas there is a strong hypersensitivity reaction with a local IgE production as well as the presence of eosinophils and an antigenic stimulation in fluids with toxocara parasitosis. The electrophoretic patterns are quite similar in both cases.
