Photo-entrainment of the circadian clock is mediated by melanopsin-expressing retinal ganglion cells (mRGCs) located in the retina. Patients suffering from diabetic retinopathy (DR) show impairment of light regulated circadian activity such as sleep disorders, altered blood pressure, and abnormal melatonin secretion. The aim of this study was to assess the impact of DR on the expression of mRGCs in the human retina.
