Blinding diseases lead to permanent vision loss by damaging photoreceptor cells, which humans cannot naturally regenerate. While researchers are working on new methods to replace or regenerate these ...

Researchers have discovered that power-producing organelles in the eye's photoreceptor cells, called mitochondria, function as microlenses that help channel light to these cells' outer segments where ...

The neurosensory retina is a complex ecosystem composed of precisely layered and diverse neurons, multiple vascular plexuses, and glial cells. It is here that visual signals from the environment are ...

A minimally invasive retinal reattachment procedure that can be done in an ophthalmologist's office leads to better long-term integrity and structure of the retina's photoreceptors - cells that allow ...

A study on ground squirrels shows, not only do mitochondria produce bioenergy in the cone-shaped photoreceptors in the retina of the eye, they also act as micro-lenses that redirect light to the ...
