Using timed treatment for eye disease: Understanding the role of Rev-erbα in the body's daily rhythms

Updated

Abstract

Disruption of the retinal circadian rhythm is associated with oxidative stress and inflammation in retinal diseases.

  • Abnormal expression of clock genes and impaired light signaling in intrinsically photosensitive retinal ganglion cells (ipRGCs) characterize retinal disease.
  • Rev-erbα and melanopsin form an antagonistic system that regulates the intraocular dopamine-melatonin rhythm.
  • Disruption of the dopamine-melatonin rhythm may lead to oxidative stress and inflammation.
  • Chronotherapy could be a promising intervention for treating retinopathies linked to circadian misalignment.
