Light-emitting sleep mask yields no long-term benefit for DME

According to the results of the phase 3 CLEOPATRA trial, patients with non-center-involving diabetic macular edema who wore a light-emitting mask during sleep did not experience long-term therapeutic benefits.
The single-masked, parallel-group, randomized controlled trial included 308 patients with DME randomly assigned to wear either a light mask during sleep (Noctura 400 sleep mask, PolyPhotonix Medical) or a sham non-light mask for 24 months. Researchers examined the change in maximum retinal thickness on OCT from baseline to 24 months.
The study included 155 patients who wore the light mask
