Scientists have discovered that donated human retinas can remain responsive to light for up to 10 hours after death when supplied with oxygen and nutrients using a specialized artificial circulation system. While this does not mean vision or consciousness can be restored after death, it marks a major advance in vision research. The breakthrough allows researchers to study living human retinal tissue for longer, improving efforts to understand diseases such as age-related macular degeneration and diabetic retinopathy. The findings could accelerate the development of new drugs, gene therapies, and regenerative treatments, while also highlighting the vital role of eye donation in advancing medical research.
