Background and objective: To evaluate the efficacy of intravitreal triamcinolone acetonide 1 week before photodynamic therapy (PDT) with verteporfin in the treatment of exudative age-related macular degeneration (AMD).
Patients and methods: Retrospective chart review of 70 eyes of 66 consecutive patients who were treated with intravitreal triamcinolone acetonide followed by standard PDT 1 week later. Group 1 consisted of 42 eyes that received one or more previous treatments with PDT alone and responded poorly. Group 2 consisted of 28 eyes that had never received PDT.
Results: No statistically significant change in mean visual acuity was seen during the follow-up period for either group. At 12 months, 90% of group 1 eyes and 80% of group 2 eyes lost less than 2 lines of Snellen visual acuity. A mean of 1.24 additional PDT sessions were required in group 1 eyes and 1.04 additional sessions in group 2 eyes during the follow-up period.
Conclusion: In eyes with exudative AMD, intravitreal triamcinolone acetonide preceding PDT with verteporfin results in stabilization of visual acuity and a decreased need for re-treatments with PDT. This regimen may be superior to PDT monotherapy.
