    Abstract:
    PURPOSE: To evaluate the efficacy of photodynamic therapy with verteporfin (PDT) and high-dose intravitreous triamcinolone acetonide to treat choroidal new vessels (CNVs) associated with age-related macular degeneration (AMD). METHODS: In this prospective, consecutive, comparative, nonrandomized, interventional case series, 30 consecutive eyes of 30 patients with subfoveal CNVs associated with AMD were treated with PDT followed by the intravitreal injection of 19.4 +/- 2.1 mg /0.1 mL triamcinolone 5 days later. Fifteen eyes had received no previous treatment (group 1), and 15 had been treated previously with PDT alone (group 2). A group of 15 eyes of 15 patients treated with PDT alone, matched for age and CNV composition and size, served as controls. Changes in best-corrected visual acuity (BCVA; logMAR), the number of Snellen lines improved or lost, and the number of PDT sessions were considered as primary outcome indicators. RESULTS: Group 1 improved an average of 0.7 +/- 3.7 Snellen lines (range, -5 to 10) (P = 0.62), group 2 lost an average of -0.7 +/- 1.5 Snellen lines (range, -5 to 1) (P = 0.08), and the control group lost an average of -2.2 +/- 0.4 Snellen lines (range, -9 to 4) (P = 0.06; Wilcoxon signed rank test). The average number of PDT treatments during the 12-month follow-up was 1.6, 1.2, and 2.8 for group 1, group 2, and the control group, respectively. Intraocular pressure rose in 8 (57%) of 14 eyes in group 1 and in 7 (50%) of 14 eyes in group 2. Cataracts developed in 4 eyes (31%) in group 1 and in 4 eyes (33%) in group 2. CONCLUSION: Combined PDT/intravitreal triamcinolone acetonide as treatment for AMD-associated CNVs was associated with improved final BCVA and reduced the need for retreatment compared with historical controls.
