Low-Dose Radiotherapy for Age-Related Macular Degeneration with Subfoveal Choroidal Neovascularization: Update of Results of the St. Gallen Prospective Randomized Study

Based on long-term experience in our hospital with low dose radiotherapy of age-related macular degeneration (AMD), we performed a prospective randomized study between November 1994 and February 1999. The aim of this double-blind study was to evaluate the extent of subfoveal choroidal neovascularization (CNV) and analyze the level of visual acuity after treatment-with different radiation doses.
