Purpose: To determine the feasibility, safety, and clinical effect of treating patients with subfoveal choroidal neovascularization (CNV) in age-related macular degeneration (AMD) with indocyanine green (ICG)-mediated photothrombosis (IMP) with and without intravitreal triamcinolone acetonide (TA). Methods: Fifteen patients (19 eyes) participated in the study. Nine eyes of seven patients were treated with IMP immediately followed by an intravitreal injection of 4 mg of TA (Group A), and 10 eyes of 8 patients were treated with IMP only (Group B). Patients had a mean follow-up of 6.9 months (range: 3 to 12 months). Patients underwent single or two sessions of IMP. Results: In Group A, visual acuity (VA) showed stability in 6 eyes (66.7%), improvement of VA in 2 eyes (22.2%), and worsening of VA in 1 eye (11.1%). Group B presented VA stability in 9 eyes (90%), and improvement in 1 eye (10%). In total, of the 15 patients (19 eyes) with IMP with or without intravitreal TA, 3 eyes (15.8%) showed improvement, 15 eyes (78.9%) stability, and 1 eye (5.3%) showed worsening of VA. A significant regression of the CNV and diminishing of subretinal fluid was demonstrated with fluorescein angiography and optical coherence tomography in both groups. No patient in Group A required retreament. Four of 10 eyes (40%) in Group B required one retreatment during the study period. Conclusions: ICG-mediated photothrombosis with and without intravitreal TA may provide stability or improvement in visual acuity and fundus findings in subfoveal CNV in AMD. Further evaluation in a multicenter, randomized, placebo-controlled clinical trial with longer follow-up is needed to accurately assess the safety and efficacy of this new treatment modality.
