How light-sensitive eye cells help control pupil size and body clock

Abstract

Intrinsically photosensitive melanopsin retinal ganglion cells are key players in regulating pupil size and circadian rhythms.

  • These cells maintain pupil diameter and are involved in the recovery and post-illumination phases of the pupillary light reflex.
  • They serve as the main source of environmental light information for the suprachiasmatic nucleus, which helps regulate circadian rhythms.
  • Recent findings enhance understanding of the histology and physiological functions of these ganglion cells.
  • A clinical framework is proposed for assessing inner retinal function through the pupillary light reflex, which may help in detecting retinal diseases.
