Answer

Studies indicate that HLA-B27 associated uveitis is a distinct entity characterized by a male predominance and frequent association with seronegative arthritic syndromes, such as ankylosing spondylitis, reactive arthritis, psoriatic arthritis, and inflammatory bowel disease. [9] The first episode of HLA-B27 associated AAU most commonly occurs in patients aged 20-40 years, whereas the age of onset of HLA-B27-negative AAU tends to occur a decade later. Of patients with AAU, 50-60% may be HLA-B27 positive. It is generally a benign nongranulomatous unilateral disease presenting as a classic triad of pain, redness, and photophobia.
