Pupillometry, the precise measurement of pupil size and dynamics, has emerged as a valuable tool in evaluating both autonomic nervous system integrity and central neural function. In particular, ...

This story is part of a series on the current progression in Regenerative Medicine. This piece is part of a series dedicated to the eye and improvements in restoring vision. In 1999, I defined ...

Until now, it has been difficult to maintain retinal ganglion cells deep inside organoids over extended periods. The supply of nutrients and oxygen in the densely packed tissues is limited, leading to ...

The chemical composition of cryogenically frozen materials that have remained hydrated is technically challenging to investigate due to the limited radiation resistance of hydrated living cells. This ...

A concern for people diagnosed with glaucoma is the uncertainty about whether they will lose their sight.While current treatments that include ...

Using adaptive optics, scientists have identified elusive retinal ganglion cells in the eye's fovea that could explain how humans see red, green, blue, and yellow. Scientists have long wondered how ...

In most retinal ganglion cells, the dendrites spread in all different directions around the cell body, Meister told __The Scientist.__ In order to find out the function of this unusually shaped subset ...

There’s an old saying, attributed to writers from Cicero to Shakespeare, that says the eyes are the windows to the soul. But it may be more accurate to say that your eyes, and in particular your ...
