Purpose: To report on visual outcome of patients receiving an intravitreal inj ection of triamcinolone acetonide as treatment of progressive exudative age-rel ated macular degeneration. Methods: The prospective comparative nonrandomized clinical interventional study included 187 consecutive patients with progressive exudative age-related macular degeneration, divided into a study group of 115 patients receiving an intravitreal injection of 25 mg triamcinolone acetonide, and a control group of 72 patients without treatment. The mean follow-up was 6.0± 4.2 months. Results: Visual acuity increased significantly (P=0.03) in the study group, and decreased significantly (P=0.01) in the control group, at 1 month an d 3 months after start of the study. Between the study group and control group, the differences in change of visual acuity were significant (P=0.001). In the st udy group, the number of patients with an increase in visual acuity of 2 or more Snellen lines was significantly (P=0.001) larger than in the control group. Cor respondingly, the number of patients with a decrease of 2 or more Snellen lines was significantly (P=0.007) smaller in the study group. In all, 43 (37.4%) pati ents of the study group experienced an increase in best visual acuity by 2 or mo re Snellen lines. Conclusions: Visual acuity increased in patients with exudativ e age-related macular degeneration at 1 month and 3 months after an intravitrea l injection of 25 mg triamcinolone acetonide.
