SHARES in retinal imagine business Optos have been removed from the London Stock Exchange following the completion of its £259 million takeover by Nikon.

Optos is one of Scotland's medical technology success stories and been listed on the main market in London since 2006.

The business was founded by Douglas Anderson in the early 1990s following an incident where a retinal detachment that was detected too late in his then five-year-old son caused the boy to lose sight in one eye.

Now around 7,000 of the devices, made at its headquarters in Dunfermline, Fife, are installed around the world.
