Cerulea Clinical Trials

Science and Research


This study is a prospective, single centre, randomized, sham-controlled, double-masked, clinical trial which aims to investigate the effect of subthreshold nanosecond laser on disease progression in eyes with intermediate age-related macular degeneration (AMD) and nascent geographic atrophy by functional and anatomical outcomes. This study is operated by the Centre for Eye Research Australia.



The study population will be individuals with high-risk intermediate age-related macular degeneration who meet all eligibility criteria. 60 subjects total (30 randomized to receive subthreshold nanosecond laser (SNL) treatment and 30 to receive sham treatment as per the 1:1 randomization).

The study has a 12-month study period with four scheduled visits: screening, randomisation (first treatment), 6-month follow up visit (with second treatment where eligible), 12-month follow-up.

The primary outcome is the proportion of laser-treated study eyes that develop late AMD compared to sham-treated study eyes over 12 months. The key secondary outcome is the change in retinal function of laser-treated study eyes compared to sham-treated study eyes over 12 months. Safety will be the proportion of laser-treated eyes that lose 10+ letters of vision (measured on a standard vision chart) compared to sham-treated eyes over 12 months.
