Doctors have discovered an extremely high rate of blindness in a remote Peruvian village where seven generations of people in Paran have a disease which causes eye damage from a young age.
A doctor last year found that among the 400 villagers of Paran, 50 were affected with the disease - that is 12 per cent of its population.
Tests in the US point to a possible cure, but for now many continue to live without their sight.
