Photodynamic Therapy of Subfoveal Choroidal Neovascularization-Interval and Number of Application of Verteporfin Treatment

ABSTRACT

PURPOSE: To evaluate the interval between, and the total number of, applications of photodynamic therapy in-patients with subfoveal choroidal neovascularization caused by various etiologies. METHODS: Ninety-five patients (108 eyes) received photodynamic therapy. At follow-up examination every 6 weeks, retreatment with the same regimen was applied if angiography showed definite fluorescein leakage. We retrospectively evaluated the interval between treatments and their total number in the group of patients who were able to be followed up for more than 6 months. RESULTS: The average number of applications of verteporfin treatment was 2.46 over a mean follow-up of 14.93 months. The average interval between treatments was 3.65 months. CONCLUSIONS: Further evaluation is needed to analyze the results of photodynamic therapy in Koreans and thereby produce a set of more accurate guidelines.
