Association of HLA antigens and primary open-angle glaucoma.

HLA testing of 55 patients with primary open-angle glaucoma revealed no increased frequencies of any of 17 HLA-A and 29 HLA-B antigens. However, the subgroup with a known family history of primary open-angle glaucoma had an increase in the frequency of the HLA-B12 antigen (48%). Intrafamily studies might further define the strength and importance of this association.
