Usefulness of HLA determination and pathergy test in the diagnosis of uveitis in Turkey.

Forty consecutive patients with uveitis constituted the probands. Behqet's disease was excluded by O'Duffy's criteria.2 The diagnosis and the localisation of the uveitis was based on clinical symptoms and signs. The nonspecific hypersensitivity to the needleprick pathergy test was done as previously described.3 The tissue typing for HLA B5 and HLA B27 was done with antisera against these 2 specificities obtained from Behringwerke AG, Marburg Lahn, W. Germany. The 2-stage NIH method was used4 and there were 2 wells for each specificity, including positive and negative controls.
