RESUMO
PURPOSE: To evaluate the efficacy and safety of dexamethasone (DEX) implant compared with inferior fornix-based sub-Tenon triamcinolone injection (PSTA) for treatment of uveitis. METHODS: A total of 48 eyes received DEX and 49 eyes received PSTA as the first treatment. RESULTS: A total of 31 eyes were implanted with DEX relapsed (64.5%) after the first injection, while 32 eyes were injected with PSTA as the first treatment relapsed (65.3%). Kaplan-Meier estimated survival to overall relapse after the first injection was a mean 20 months± 3.6 months for DEX (median,7) and 14 months± 1.9 months (median,9) for the PSTA (P = 0.505). Of 49 eyes receiving the PSTA implant as the first treatment, inflammation persisted in 14.3% after the first injection but persisted in none after the DEX injection (P = 0.005). CONCLUSIONS: DEX implantation achieved a higher rate of disease control in the initial 12 weeks postinjection with a relative equivalence in the duration of effect and relapse rates when compared with PSTA.
