Dennis Mee, aged 78, was the first person to use the £50,000 Occular Coherance Tomography machine at Perspective Opticians in Drury Lane last December.
But what started out as ‘a bit of fun’ revealed Mr Mee was suffering from Wet Macular Degeneration, the largest cause of vision loss in the western world.
“It’s a fantastic piece of equipment. It put me in a position where I could go to the hospital and get treatment straight away so I didn’t lose my eyesight,” said the grandfather of two.
“It needs quick treatment or anything can happen up to going blind so I’m very fortunate I got to it.”
