Scottish researchers develop low-cost 3D imaging device

University of Strathclyde researchers have developed prototype technology that could increase access to screening for eye conditions such as glaucoma.

The simple, inexpensive device can be added to a slit lamp, capturing 3D images of the retina and cornea.

Dr Mario Giardini, who was involved in the development of the device, highlighted that the technology enables patients to have images captured inexpensively, without the need for a specialist to be present.

“Our device reliably takes 3D images, and it is comfortable and fast, in less than a second,” he said.

Giardini added that the device has the potential to make eye diagnostics more accessible and reduce inequalities.

“The technology has the potential to revolutionise the screening and follow-up within the community of conditions such as glaucoma, as any optometrist, anywhere in the world, could afford it,” he said.

Consultant ophthalmologist, Dr Iain Livingstone, explained that the device uses visible light to recreate a high-fidelity 3D representation of structures within the eye.

“It’s a crucial addition to the way we interpret information, harnessing digital to glean so much more from a slit lamp exam, with potential reach far beyond the hospital toward community optometry,” he emphasised.

The initial prototyping was funded by the Engineering and Physics Research Council, part of UK Research & Innovation.
