In efforts to tackle the leading cause of blindness in developed countries, researchers have recruited nanotechnology to help regrow retinal cells.

Macular degeneration is a form of central vision loss, which has massive social, mobility, and mental consequences. It impacts hundreds of millions of people globally and is increasing in prevalence.

The degeneration is the consequence of damaged retinal pigment cells. Our bodies are unable to grow and replace these cells once they start dying, so scientists have been exploring alternative methods to replace them and the membrane within which they sit.
