A blind boy born with an "untreatable" eye condition is travelling to China to receive a revolutionary stem cell therapy that could partially restore his sight.
Joshua Clark, who is 22 months old, suffers from Optic Nerve Hypoplasia, a congenital condition that causes under-development of the optic nerve.
His parents, Anthony and Joanna Clark from Caernarfon, North Wales, were told by doctors there was no available treatment for the illness, but heard about the stem cell therapy through the internet.
After raising £40,000 through a local fundraising appeal, the family is due to arrive in China on Thursday to begin the treatment at a specialist hospital in the city of Hangzhou, two hours from Shanghai.
"Joshua is absolutely fantastic, he's none the wiser at the moment," said Mrs Clark a 35-year-old police officer with North Wales Police before boarding a flight from Heathrow.
