Conditions

Diabetic Retinopathy

Brief summary

This study will test the effects of a 6-week comprehensive circadian optimization intervention Amplify-RHYTHM in patients with diabetic retinopathy. The outcomes of interest are objective and subjective sleep parameters, evening salivary cortisol and melatonin levels, and glucose parameters from continuous glucose monitoring

Detailed description

This study will test the effects of a 6-week comprehensive circadian optimization intervention Amplify-RHYTHM in patients with diabetic retinopathy. The two main components of the intervention are timed light exposure and weekly remote coaching session by psychologist to optimize circadian and sleep behaviors. The outcomes of interest are objective and subjective sleep parameters, evening salivary cortisol and melatonin levels, and glucose parameters from continuous glucose monitoring

Interventions

BEHAVIORALAmplify-RHYTHM

Amplify-RHYTHM will have two main components: 1) timed light exposure (increase light in the morning, blue light reduction in the evening and eye masks at night), 2) weekly remote coaching session by psychologist to optimize circadian and sleep behaviors
