Real-World Experience of Fluocinolone Acetonide 0.19 mg in the Management of Non-Infectious Uveitis.

ABSTRACT

PURPOSE: This study aims to evaluate the real-world efficacy and safety profile of fluocinolone acetonide (FAc) implants for the treatment of non-infectious uveitis (NIU). METHODS: A retrospective, observational study was conducted at Moorfields Eye Hospital, London, involving patients who received FAc 0.19 mg implants (Iluvien®) for NIU. 2-year follow-up data on baseline characteristics, indications, and outcomes was collected. The primary indicator for treatment failure was defined as the need for rescue treatment with dexamethasone (DEX) implants, while secondary indicators included changes in steroid and systemic immunosuppression requirements, or the need for a second FAc implant before 3 years. The occurrence of complications was collected. RESULTS: Of the 146 eyes treated with FAc implants, 24.0% experienced treatment failure requiring DEX implant within 2 years. About 42.9% required this within the first 6 months. There was an increase in the number of patients requiring steroids and/or systemic immunosuppression. Within the first 2 years post-FAc implant, only 13.7% experienced an IOP rise, with 4.1% requiring IOP-lowering surgery. About 57.9% of the phakic eyes developed cataracts. CONCLUSION: This study provides valuable real-world evidence supporting the efficacy of FAc implant in NIU. It demonstrates a good safety profile at 2 years, with a significant reduction in uveitis recurrence rate and treatment burden. Our results are especially pertinent to the treatment of uveitic cystoid macular oedema (CMO), which was the primary indication in over 75% of our patients. Furthermore, it suggests that while FAc implant controls retinal inflammation effectively, choroidal inflammation would require alternative treatment.
