[A study in immunofluorescence of the plasma cells in allergic conjunctivitis, in particular of the cells forming immunoglobulin E (IgE) (author's transl)].

The relatively simple and precise technique of direct immunofluorescence on a tissue section enables the study and enumeration of all types of plasma cells including mastocytes (stained with acridine orange) in normal conjunctiva (5 cases), chronic non-allergic conjunctivitis (5 cases), allergic conjunctivitis of the educt (11 cases) and vernal conjunctivitis (11 cases). There is evidence of elevation of IgE plasma cells in type I allergic conjunctivitis where they are twice as raised as in non-allergic cases in adult forms, and three times more elevated in vernal conjunctivitis. There was no correlation between the number of IgE plasma cells in the tissues and IgE level in sera. Thus in air-borne conjunctival allergies local hypersensitivity seems to be the predominant, even exclusive, feature.

Lymphocyte transformation test in uveal pathology.

Comparative studies of skin tests and in vitro lymphocyte transformation tests were found to be fruitful with the following antigens: tuberculin and PPD, Streptococcus, vaccine and protein M of Streptococcus, candidin, herpes antigen, Brucella antigen, antigen from autologous saliva. Three types of response occur: (1) positive skin test with syndromic ocular reaction and positive LTT: the diagnosis of hypersensitivity is certain; (2) positive skin test without syndromic reaction but positive LTT in vitro; less sensitive than the in vivo test but enhancing the value of the latter; the diagnosis is presumptive, and (3) skin test positive or negative and LTT negative: indicates that the in vitro test is less sensitive than the in vivo one. Practical interest of this comparison stems from those cases in whom skin testings is contra-indicated because it is considered to be dangerous (macular choroiditis, Eales' disease). Specific desensitization treatment was carried out on most of the cases and seemed to be effective in several of them.
