Intravitreal Triamcinolone Injection for Uveitic Macular Edema: A Randomized Clinical Study

Purpose: To evaluate the additive effect of intravitrial triamcinolone (TA) injection in uveitic macular edema compared to systemic anti-inflammatory treatment only.Methods: Patients were randomized into the intravitreal TA injection group and the sham group. All patients received systemic anti-inflammatory treatment with follow-up monthly to 6 months, with additional treatment as needed.Results: Fifty eyes of 50 patients were enrolled. Central foveal thickness decreased significantly from month 1 in the TA group, and from month 3 in the sham group. Parafoveal area thickness significantly decreased in both groups from month 1, with greater decrease in the TA group at months 2 and 3. Leakage area on fluorescein angiography was significantly smaller in the TA group at months 1 to 3. Intraocular pressure increased in the TA group at months 1 and 2.Conclusions: Intravitreal TA injection showed earlier reduction of leakage and retinal edema compared to systemic anti-inflammatory treatment alone.
