Impact of HLA-B51 on Uveitis and Retinal Vasculitis: Data from the AIDA International Network Registries on Ocular Inflammatory Disorders
The clinical relevance of HLA-B51 in relation to Behçet’s disease-related uveitis and non-infectious uveitis not associated with BD.

This pioneering study has shed new light on ocular inflammation in patients with HLA-B51, even in cases without a specific diagnosis of Behçet’s disease (BD). Analyzing records from 213 patients (341 eyes) through the International AIDA Network registries for Behçet’s disease and non-infectious uveitis (NIU), researchers compared three key groups: NIU unrelated to BD but positive for HLA-B51, BD-related uveitis positive for HLA-B51, and BD-related uveitis negative for HLA-B51. In particular, the study examined any differences in long-term ocular complications, visual acuity, anatomical patterns, and the incidence of retinal vasculitis or macular edema. Among other results, a notable finding emerged: NIU patients carrying the HLA-B51 haplotype have a significantly higher risk of developing retinal vasculitis, regardless of a systemic BD diagnosis. Therefore, this groundbreaking research highlights the importance of HLA-B typing for patients with NIU or retinal vasculitis, even if they do not display classic Behçet’s disease symptoms. This opens new avenues for understanding and managing ocular inflammatory conditions associated with HLA-B51.
