HLA antigens and primary open-angle glaucoma in black Americans.

Black patients with primary open-angle glaucoma, when compared to nonglaucomatous individuals, demonstrate significantly increased prevalences of the HLA antigens B7 and B12 and significantly decreased frequencies of A1 and A11. White patients with primary open-angle glaucoma have in common with blacks the increases in B7 and B12 and the decrease in A11, but present no deficit of A1. In addition, white patients with primary open-angle glaucoma demonstrate a significant increase of A3 and a decrease of Bw35, both of which are not found in blacks.
