Researchers at the University of California, Irvine have found a potential treatment to slow or reverse age-related vision loss. They tested a simple fatty acid that improved visual performance in older mice.

This is one of the most common signs of aging: changes in eyesight. You might notice your parents or grandparents having trouble reading menus or watching TV without glasses. But what if this gradual decline in vision could be reversed? A team of researchers at the University of California, Irvine has been exploring this possibility.

Their latest study investigates a potential treatment aimed at slowing or reversing 'aging' in the eye while also helping prevent conditions like age-related macular degeneration (AMD). The research involved collaborators from UC Irvine, the Polish Academy of Sciences, and the Health and Medical University in Potsdam, Germany. The findings were published in Science Translational Medicine.

The study builds on earlier research focused on a gene called ELOVL2, which is widely recognized as a marker of aging. In that earlier work, increasing ELOVL2 activity in older mice raised levels of the omega-3 fatty acid docosahexaenoic acid (DHA) in the eye and improved visual function.

In this newer study, researchers tested whether supplying the eye with the right fatty acids could help. They injected older mice with a specific polyunsaturated fatty acid and observed improved visual performance. 'It's a proof-of-concept for turning lipid injection into a possible therapy,' says Dorota Skowronska-Krawczyk, PhD.

The researchers also identified genetic variants in the ELOVL2 enzyme that are associated with faster progression of AMD. This discovery could lead to more targeted treatments and earlier interventions aimed at preventing serious vision decline.

Why It Matters

This research has implications for older people in India who may struggle with age-related vision loss. It also highlights the importance of genetics and lipid metabolism in maintaining healthy vision.
