Treatment of refractory posterior uveitis with infliximab: a 7‐year follow‐up study

Objective: To describe, in a 7‐year follow‐up study, the use of infliximab in patients with refractory posterior uveitis and scleritis. Methods: A 7‐year follow‐up case series study was performed. Patients with posterior uveitis and scleritis refractory to conventional therapies (steroids and at least one immunosuppressive agent) were included. Three infliximab intravenous doses of 5 mg/kg were administered at weeks 0, 2, and 6. Further infusions were allowed in patients undergoing a relapse of the uveitis after initial remission. All patients were followed up for at least 8 months. We defined uveitis improvement as an increase in the best‐corrected visual acuity or an objective and significant improvement in retinal exudates and/or haemorrhages, cystoid macular oedema (CME), and vitreous haze. Infliximab‐related adverse events, final prednisone doses, and the number of immunosuppressive agents used were recorded. A descriptive analysis was performed. Results: A total of 11 patients (17 eyes were affected at baseline) were included, 63% were women, the mean age was 43±14 years, and the median follow‐up was 80 months (p25–p75: 50–80). After infliximab treatment, six eyes maintained their basal visual acuity, nine eyes showed improvement, and two worsened (in the two patients diagnosed with choroiditis). Vitreous haze, active retinal vasculitis, and CME, but not chorioretinal lesions, improved in all patients. All patients tapered their daily steroid dose and the number of immunosuppressive agents. No infliximab‐related adverse events were reported. Conclusions: Infliximab could be an effective and safe treatment in patients with posterior uveitis and scleritis refractory to conventional therapy.
