 This is a randomized controlled study of non-damaging photothermal macular grid laser versus sham laser therapy in patients with dry age-related macular degeneration AMD and large high-risk drusen. The goal of the study is to determine if this treatment will reduce macular drusen volume and also whether this might improve visual acuity or reduce the risk of conversion to advanced age-related macular degeneration defined as development of choroidal neovascularization or geographic atrophy.
