Abstract
PURPOSE: To evaluate the secondary and exploratory outcomes of the Laser Intervention in Early Stages of Age-Related Macular Degeneration (LEAD) study, a 36-month trial of a subthreshold nanosecond laser (SNL) treatment for slowing the progression to late age-related macular degeneration (AMD) in its early stages. DESIGN: Multicenter, randomized, sham-controlled trial. PARTICIPANTS: Two-hundred ninety-two patients with bilateral large drusen. METHODS: Participants were randomly assigned to receive SNL or sham treatment to the study eye at 6-month intervals. MAIN OUTCOME MEASURES: The secondary outcome measure of the LEAD study was the time to development of late AMD, defined by multimodal im..

The Centre for Eye Research Australia receives operational infrastructure support from the Victorian Government. Ellex R&D Pty Ltd. (Adelaide, Australia) provided partial funding of the central coordinating center and the in-kind provision of Ellex 2RT~ laser systems, ongoing support of those systems, and the Macular Integrity Assessment microperimeters for the duration of the study. The web-based Research Electronic Data Capture (REDCap) application and open-source platform OpenClinica allowed secure electronic data capture. The study is sponsored by the Centre for Eye Research Australia, an independent medical research institute and a not-for-profit company.
