A team of researchers has developed experimental eye drops containing photoswitchable small molecules that restore saccadic eye movements and visually guided behaviors in blind mice. This breakthrough, led by scientists at the Institute for Bioengineering of Catalonia (IBEC), could pave the way for treating advanced retinal degeneration in humans. The study demonstrates that these molecules can activate light-sensitive proteins in damaged retinas, enabling photoreceptor cells to respond to ambient light even when traditional vision is lost. This approach is notable for its potential universality, as it works independently of specific genetic mutations or retinal disorders, making it applicable to a wide range of patients. The research was funded by multiple organizations including Fundaluce, CaixaHealth, and the Government of Catalonia, with significant contributions from Rosalba Sortino's doctoral thesis at the University of Barcelona. If successful in human trials, this technology could offer an affordable and accessible alternative to existing vision-restoration methods, particularly for individuals with advanced retinal degeneration who currently lack effective treatments. The findings were published in the Journal of the American Chemical Society and highlight the promising future of gene therapy and molecular engineering in ophthalmology.

From Turin comes a surgical world-first: the simultaneous transplant of a complete human macula, along with the cornea, sclera, and connective tissue, from one of the patient’s eyes to the other. It allowed a woman blind for several years to immediately gain enough vision to recognize both her son and her faithful canine companion, Joe.
