Scientists have taken a significant step forward in their search for the origin of a progressive eye condition which causes sight loss and can lead to corneal transplant.
A new study into keratoconus by an international team of researchers, including a University of Leeds group led by Chris Inglehearn, Professor of Molecular Ophthalmology in the School of Medicine, has for the first time detected DNA variations which could provide clues as to how the disease develops.
Keratoconus causes the cornea, which is?the clear outer layer?at the front of the eye, to thin and bulge outwards into a cone shape over time, resulting in blurred vision and sometimes blindness. It usually emerges in young adulthood, often with lifelong consequences, and affects 1 in 375 people on average, though in some populations this figure is much higher.
