Abstract

Objective

This study aimed to test the hypothesis that patients presenting with anterior uveitis who are HLA-B27 positive, either with or without associated systemic disease, have a less-favorable outcome than do patients with idiopathic anterior uveitis who are HLA-B27 negative.

Design

Retrospective case-controlled series.

Participants

Ninety-seven patients who were HLA-B27 positive with no systemic disease, 94 patients who were HLA-B27 positive with systemic disease, and 72 patients who were HLA-B27 negative who presented with anterior uveitis were studied.

Main outcome measures

Ocular complications (e.g., secondary glaucoma, cataract formation, pupillary synechiae, vitritis, cystoid macular edema, and optic disc edema), medical and surgical treatment, number of recurrent attacks, and final visual acuity were recorded for all patients.

Results

The patients who were HLA-B27 positive, either with or without systemic disease, experienced a greater number of complications than did the patients who were HLA-B27 negative. Periocular corticosteroids, systemic corticosteroids, and systemic immunosuppressive chemotherapy were required in a far greater number of HLA-B27-positive patients than in HLA-B27-negative patients (60% vs. 11%, 53% vs. 7%, and 18% vs. 1%, respectively; P < 0.001). The percentage of legally blind eyes was significantly greater in the HLA-B27-positive group, both with and without systemic disease, when compared with the HLA-B27-negative group (11% vs. 2%; P < 0.005).

Conclusions

The prognosis of anterior uveitis associated with the HLA-B27 haplotype, either with or without associated systemic disease, is less favorable when compared with that of HLA-B27-negative patients with idiopathic anterior uveitis.

Patients and methods

The clinical records of all patients with anterior uveitis seen at the Immunology & Uveitis Service, Massachusetts Eye & Ear Infirmary, between January 1982 and December 1993 were analyzed throughout patients’ entire follow-up and the following data were obtained: gender, race, age at presentation, age at onset of uveitis, follow-up time, clinical diagnosis or systemic disease association or both, clinical presentation, number and duration of recurrent inflammatory attacks, prevalence of severe

Results

A total of 191 consecutive patients, representing 28.2% of patients with anterior uveitis, referred to our service tested HLA-B27 positive and had no other primary ocular diagnosis and/or systemic disease association other than seronegative spondyloarthropathy or inflammatory bowel disease or both. Seventy-two patients (122 eyes) tested HLA-B27 negative and suffered from anterior uveitis of unknown etiology (idiopathic). The HLA-B27-positive group was further divided into 97 (50.8%) patients

Discussion

Anterior uveitis is the most common form of uveitis, and its association with the HLA-B27 haplotype in the white population has been estimated to be approximately 50%.14, 15 Patients with HLA-B27-positive anterior uveitis frequently present with unilateral or bilateral alternating, nongranulomatous, recurrent iridocyclitis in association with nonspecific arthritic symptoms or with a seronegative spondyloarthropathy.9 These clinical characteristics have made this group of patients

    Psoriatic arthritis is an inflammatory, seronegative, spondyloarthropathy (SpA) that is associated with HLA B27 positivity in 10–25%5,6 and has been reported in up to 30% psoriatic patient and usually manifests as asymmetrical oligoarthritis.7 There is a known association of uveitis and HLA-B27 spondyloarthropathies, including psoriatic arthritis.7,8 The ocular involvement in psoriatic arthritis in the form of uveitis is severe and recurrent.7,8
