INTRODUCTION: Anterior uveitis (AU) without underlying systemic disease sometimes requires immunomodulatory therapy (IMT) to control inflammation. Our primary purpose was to characterize the immunomodulatory therapy profile in patients with idiopathic AU (IAU) at our ophthalmology department.METHODS: Data from all patients with AU under IMT evaluated in the past 10 years at the uveitis department of Hospital de S. João were reviewed. Data regarding demographics, type and duration of IMT, the pattern of disease remission and relapses were noted.
RESULTS: A total of 158 patients with AU under IMT were reviewed, from whom 30 patients with IAU were included and 128 patients with underlying systemic disease were excluded. The mean total follow-up time was 73.87±44.73 months [range 12-168]. Twenty-one patients (70%) presented bilateral involvement. The mean duration of treatment was 46.50±34.40 months and 21 patients (70%) were under IMT for at least 2 years. Methotrexate was the most widely used immunomodulator agent able to maintain disease remission (n=26, 86.7%) and the first attempt in IMT in 96.2% of the patients. Two patients (6.7%) needed the association of methotrexate and adalimumab to control the disease. Before treatment, patients presented a mean of 2.07±1.31 flare-ups per year, significantly decreasing to a mean of 0.60±0.67 relapses per year with the implementation of IMT (p<0.001). Twelve patients (40%) stopped treatment, in 5 cases (41.7%) a medical-based decision because of long-term remission of the disease, in 5 cases (41.7%) by patient initiative and in 2 cases (16.7%) because of medication side effects. Three (25%) of these 12 patients developed recurrence after a mean period of 10.67±6.43 months without IMT [range 6-18]. All patients who stopped IMT based on medical decision had been treated for a minimum of two years [range 2-5.8] without relapse of ocular inflammation.
CONCLUSION: Some patients with IAU need IMT to achieve the ultimate goal of durable remission. Methotrexate was the most widely used immunomodulatory drug for the treatment of IAU in our department. The medical decision to stop IMT based on a 2-year remission period appears to be a safe approach.
