PURPOSE: To assess the efficacy and tolerability of interferon (IFN) alpha-2a in post-infectious uveitis secondary to presumed intraocular tuberculosis (IOTB). METHODS: Patients with chronic uveitis secondary to presumed IOTB who, after completing an antitubercular treatment, showed poor response to treatments or recurred after tapering oral corticosteroids to ≤7.5 mg/day were enrolled. All patients were treated with IFN alpha-2a subcutaneous injections. Best-corrected visual acuity (BCVA), central retinal thickness (CRT), and inflammatory signs were compared between baseline and follow-up visits up to six months. RESULTS: Twelve eyes (six patients) were enrolled. Mean BCVA improved from 0.64 ± 0.55 logMAR at baseline to 0.32 ± 0.31 logMAR at 6 months (p = 0.03). Mean CRT decreased from 372 ± 132.2 μm to 274.66 ± 34.9 μm at six months (p = 0.01). Inflammatory signs (vitritis, vasculitis) also decreased overtime. No major complications or tuberculosis reactivations were recorded. CONCLUSIONS: IFN alpha-2a was efficacious and safe in treating chronic post-infectious uveitis secondary to presumed IOTB.
