Research to Prevent Blindness

Novel Pathway Helps Eyes Quickly Adapt to Darkness

Muller cells

When Müller cells (marked with asterisks) were destroyed, cone cells quickly ran out of photopigments and could not adapt to dark.

Scientists have uncovered a previously unknown pathway in the retina that allows photoreceptor cells to adapt following changes in light exposure. The discovery could help scientists better understand diseases that affect the retina.
