Libby Clegg is a double Paralympic champion sprinter who won silver at the 2008 Summer Paralympics and gold in Rio at the 2016 Paralympic Games, where she broke the world record for her sprinting performance.
The Paralympian’s next challenge will be on ITV’s Dancing on Ice 2020, which starts in January.
The fact that Libby lives with the degenerative eye condition makes her extensive list of achievements and goals all the more impressive.
Libby lives with Stargardt disease, a a rare inherited condition affecting one in 8,000 to 10,000 people in the UK, according to the NHS.
In Stargardt’s the light-sensitive layer of cells in the macular region of the eye degenerate.
The macular is the area at the back of the eye which is responsible for the fine detailed vision necessary for activities such as watching TV and reading, explains the NHS.
Whilst people with Stargardt’s do not lose their peripheral (side) vision, many people will reach the point of severe vision loss.

Libby added: “But you get the feeling that you’re falling forward into nothing, and you have no concept of where the ground is. It made me feel sick at first.”
According to the NHS, the main symptoms Stargardt disease are:
- A loss of detailed vision and colour perception
- Wavy vision
- Blind spots
- Difficulty adapting to low light levels
Can it be treated?
UV-blocking sunglasses can offer some protection for remaining vision. At the moment, however, Stargardt’s is untreatable, says the NHS.
A number of novel interventions are currently under investigation, including stem cell therapies, which hold some promise, reports the health site.
“Stem cells are a special type of cell which, when put under the right conditions, can develop into many other types of cell including those found in the macular,” explained the health body.
It is hoped that new cells derived from stem cells can be grown in a laboratory to be transplanted into the eye to replace areas of dead or non-functioning cells, says the medical site.
Stem cells can be sourced from a number of places including blood, bone marrow, umbilical cord and fertilised egg cells.
“More research will need to be undertaken in the future to determine to what extent stem cell therapy might help improve vision for people with Stargardt’s,” added the NHS.
