Abstract

Purpose:

To assess long-term effectiveness of rituximab therapy for refractory noninfectious uveitis affecting the posterior segment.

Methods:

Retrospective case series. Patients diagnosed with recalcitrant noninfectious posterior uveitis who were treated with rituximab intravenous infusions between 2010 and 2015 were included. Patients underwent best-corrected visual acuity testing and fluorescein angiography evidence of disk or vascular staining at 6, 12, 18, and 24 months. Patients had at least 24 months of follow-up.

Results:

Eleven patients (21 eyes) with refractory posterior uveitis treated with intravenous rituximab were included. Nine (81.8%) patients were female. Mean follow-up was 29.3 ± 7.8 months. rituximab was administered as complementary therapy because of previous inefficacy of other therapies in 7 (63.7%) patients, and it was the only treatment in four (36.3%) patients who did not tolerate other drugs. Inflammation signs by fluorescein angiography were controlled in nine (81.8%) patients at the end of follow-up. Baseline best-corrected visual acuity was 20/80 (logarithm of the minimal angle of resolution 0.6 ± 0.4), and final best-corrected visual acuity was 20/40 (0.3 ± 0.5) (P = 0.005). No significant side effects were reported.

Conclusion:

Rituximab therapy was associated with stability and remission of recalcitrant noninfectious posterior uveitis in patients who did not tolerate or did not respond to other therapies.
