Abstract

BACKGROUND: A novel, ultra-low energy nanosecond laser (retinal rejuvenation therapy) has been developed with the aim to slow progression of early age-related macular degeneration (AMD). The safety, changes in fundus characteristics and macular function in a cohort of participants with bilateral intermediate AMD are reported. DESIGN: Prospective non-randomised, pilot intervention study. PARTICIPANTS OR SAMPLES: Subjects with bilateral intermediate AMD (n = 50, aged 50-75 years). METHODS: Ultra-low energy laser pulses applied in 12 spots around the macula of one eye (0.15-0.45 mJ), using 400 μm diameter spot, 3 nanosecond pulse length, 532 nm wavelength and energy titrated to each patient.
