BACKGROUND AND OBJECTIVE: To evaluate the role of photodynamic therapy (PDT) in the management of vascularized pigment epithelial detachment in age-related macular degeneration (AMD) when the pigment epithelial detachment is the predominant component of the neovascular complex. PATIENTS AND METHODS: Seventeen eyes of 17 patients underwent indocyanine green angiography-guided PDT and had at least 6 months of follow-up. Data retrieved included visual acuity and angiographic features prior to the treatment, number of PDT sessions, visual acuity, angiographic outcomes at the end of the follow-up, length of follow-up, and status of the fellow eye. in the series, with an average age of 77 years and a mean follow-up time of 11 months. Six (35%) of the patients lost less than 3 lines of visual acuity, 6 (35%) lost between 3 and 6 lines, and 5 (30%) lost 6 or more lines. Angiographic outcomes were categorized as failures in 14 (82%) of the treated eyes and successful in 3 (17%) eyes. CONCLUSIONS: In 82% of the eyes, PDT failed to flatten the pigment epithelial detachment or prevent growth of the choroidal neovascular membrane. Visual acuity outcomes correlated poorly with angiographic outcomes. PDT does not seem to improve the prognosis of eyes with large pigment epithelial detachments in AMD.
