The more precisely we want to examine the human retina, the more clearly one of the fundamental limits of physics becomes apparent. In cellular-resolution eye imaging, the same tradeoff has applied ...

Researchers at the University of Twente and Radboudumc are developing a promising new model to enhance understanding of the human retina. They are developing a retina-on-a-chip, in which the three ...

During retinal development, Setd8 safeguards chromatin accessibility through the histone marker H4K20me1. When Setd8 is present (right), genes required for retinal progenitor cell maintenance and DNA ...

For individuals with inherited eye disorders such as retinitis pigmentosa or macular degeneration, the irreversible degeneration of the retina—a layer of photoreceptors at the back of the eye—can ...

A hybrid retinal implant using stem-cell-derived neurons and microelectrodes lowers activation thresholds and improves signal precision, offering a more natural interface for high-resolution vision ...

Photoreceptors are specialized neurons that convert light into electrical signals that are processed in the visual cortex to form images. The RPE is a cell layer that is adjacent to the photoreceptors ...

Scientists at USC are launching a new trial to test a tiny stem cell implant that could restore vision in people with advanced dry macular degeneration. The hair-thin patch replaces damaged retinal ...

The bird retina is one of the most energetically expensive tissues in the animal kingdom, yet it doesn’t use the energy advantage of oxygen. New research finally explains how this is possible.

Researchers have developed a soft contact lens embedded with electrical stimulation electrodes that, in a mouse model of ...
