Neuroscience Regenerative Medicine Retina Retinitis Pigmentosa Visual Processing

Basic Research

Grantee

Millions of Americans are progressively losing their sight as cells in their eyes deteriorate, but a new therapy developed by researchers at the University of California, Berkeley, could help prolong useful vision and delay total blindness.

The treatment — involving either a drug or gene therapy — works by reducing the noise generated by nerve cells in the eye, which can interfere with vision much the way tinnitus interferes with hearing. UC Berkeley neurobiologists have already shown that this approach improves vision in mice with a genetic condition, retinitis pigmentosa, that slowly leaves them blind.
