Protein-transport discovery may help define new strategies for treating eye disease
Many forms of vision loss stem from a common source: impaired communication between the eye and the brain. And at the root of that communication are hundreds of proteins generated by the retina's nerve cells. A new study examines these proteins in unprecedented detail, providing surprising new insights into how visual signals are distributed to different regions of the brain. (2019-08-21)

Regenerating human retinal ganglion cells in the dish to inform glaucoma treatment
People have a limited ability to regenerate nerves after injury or illness.

Now, researchers at the University of Nebraska Medical Center, USA, can induce human retinal ganglion cells, which form the optic nerve, to regenerate nerve fibers in a dish. This study providing a new system for nerve regeneration research. (2019-07-02)

NTU Singapore scientists develop 'contact lens' patch to treat eye diseases
NTU Singapore scientists have developed a 'contact lens' patch with microneedles that could be a painless and efficient alternative to current methods of treating eye diseases such as glaucoma. Patients are unable to keep up with the prescribed regime of current localised treatment methods like eye drops, which are hindered by the eye's natural defences, blinking and tears. Eye injections can be painful and carry an infection risk and eye damage. (2018-11-20)

A major step toward non-viral ocular gene therapy using laser and nanotechnology
Gold nanoparticles, which act like 'nanolenses,' concentrate the energy produced by the extremely short pulse of a femtosecond laser to create a nanoscale incision on the surface of the eye's retina cells.
