Answer

In ophthalmology, HLA associations are strongest in diseases of the uvea. Of patients with uveitis, 19-88% have the HLA-B27 phenotype, depending upon the study population cited. Acute anterior uveitis (AAU) as depicted in the image below, may occur as a distinct clinical entity or in conjunction with a group of autoimmune rheumatic diseases called seronegative spondyloarthropathies. [2] By definition, patients with these diseases do not have circulating  rheumatoid factor, hence the term seronegative. [3, 4]
