Acute anterior uveitis is the most common form of uveitis. HLA-B27-associated acute anterior uveitis is a distinct clinical entity that has wide-ranging medical significance due to its ocular, systemic, immunologic, and genetic features. The association between HLA-B27 and the spectrum of HLA-B27-associated inflammatory diseases remains one of the strongest HLA-disease associations known to date. This review examines acute anterior uveitis with particular focus on HLA-B27-associated acute anterior uveitis, including the epidemiology, immunopathology, association with HLA-B27 and its subtypes, clinical features, complications, prognosis, and potential new therapies such as anti-TNFalpha therapy and oral HLA-B27-peptide tolerance. There have been substantial recent advances in both clinical and basic scientific research in this field, including studies of the various animal models of acute anterior uveitis and the HLA-B27 transgenic animals, and these are summarized in this review. To the ophthalmologist, HLA-B27-associated acute anterior uveitis is an important clinical entity that is common, afflicts relatively young patients in their most productive years, and is associated with significant ocular morbidity due to its typically recurrent attacks of inflammation and its potentially vision-threatening ocular complications. Furthermore, to the ophthalmologist and the internist, HLA-B27-associated acute anterior uveitis is also of systemic importance due to its significant association with extraocular inflammatory diseases.

Pterygium is an active, invasive, inflammatory process, a key feature of which is focal limbal failure. In a two-stage process, "conjunctivalization" of the cornea occurs with tissue characterized by extensive chronic-inflammation, cellular proliferation, connective tissue remodeling, and angiogenesis. An understanding of this process has resulted in efforts aimed at limbal reconstruction, which is considered the gold standard for surgical care. Although good results have been obtained with other treatment methods, a long-term approach to follow-up with at least 5-year survival figures is desirable. Sophisticated analyses of the tear film and surface epithelium in patients with pterygium may help explain symptoms. The efficacy, at least in the short term, of nonsteroidal anti-inflammatory drugs in the treatment of inflamed pterygia has been confirmed. Corneal topographic analysis has shown that surgery reduces induced astigmatism and also causes subtle changes that may explain postsurgical improvements in vision.
