Photodynamic Therapy For Recurred Subfoveal Choroidal Neovascularization After Argon-Laser Photocoagulation

Purpose: To evaluate the effects of photodynamic therapy for subfoveal recurrences of juxtafoveal or extrafoveal choroidal neovascularization (CNV), previously treated with argon-laser photocoagulation. Methods: Seven eyes, previously treated with argon-laser photocoagulation for juxtafoveal or extrafoveal choroidal neovascularization, received photodynamic therapy for subfoveal recurrence. Changes in visual acuity and fluorescein angiographic findings were analyzed. Results: The average time of appearance of recurrent CNV after laser photocoagulation was 43.14±29.62 months (range, 2-77 months). After photodynamic therapy, fluorescein leakage and neovascular lesion size decreased in all patients on fluorescein angiography. Visual acuity was stabilized or improved in 5 of 7 eyes. Conclusions: Photodynamic therapy was effective in patients with subfoveal recurrences of juxtafoveal or extrafoveal choroidal neovascularization previously treated with argon-laser photocoagulation.
