New device could revolutionise eye disease diagnosis - creating eye maps on the high street

06.03.2007
A new digital ophthalmoscope, devised by a research team led by the University of Warwick, can provide both doctors and high street optometrists with a hand-held eye disease diagnosis device equal to the power of bulky hospital-based eye diagnosis cameras. It will also give optometrists the ability to email detailed eye maps of patients to specialist eye doctors.

Ophthalmoscopes, which act as an illuminated microscope for the eye, have changed little in design in the last century. As a result the effective operation of the device is constrained by the skill, expertise and eyesight of the eye specialist.

The new digital ophthalmoscope (developed from a three-year research partnership bringing together the University of Warwick, ophthalmoscope manufacturer Keeler Optics, City University, & UCL) uses a combination of specialist lens digital imaging and lighting technology which for the first time allows a high quality digital image to be captured and recorded by an ophthalmoscope.

University of Warwick research Professor Peter Bryanston-Cross has also been able to apply software used to stitch together detailed map images to assemble the captured images from the digital ophthalmoscope. This produces a highly detailed single picture of medical significance and usefulness. It provides a map of the eye equal to the field of view and resolution of the large “Fundus” cameras typically used in hospital settings to examine eyes. The new digital ophthalmoscope would also be around 10 times cheaper than a Fundus camera.

This technology will be a powerful tool in the hands of specialist eye doctors, but it will also revolutionize eye care on the high street. Previously high street opticians have had to rely on notes and hand drawn sketches when referring customers to eye clinics. This new technology will allow them to create and email detailed eye images to hospital specialists cutting patient referral and diagnosis times and massively easing the burden on expensive and overstretched hospital eye equipment.

Warwick Hospital consultant eye surgeon Gary Misson has been working with Professor Peter Bryanston-Cross’s digital ophthalmoscope research digital programme for several years. He says:

“This is an exciting development as it makes an instrument that is traditionally difficult to use much easier to handle and therefore available for use to a wider range of health care workers. It will allow digital images of disease such as the potentially blinding complications of diabetes and glaucoma to be accurately and quickly sent to specialists who will then be able to arrange appropriate treatment. I foresee a relatively inexpensive instrument that is about the size of a mobile phone in common use in the near future”

Im Focus: New interactive machine learning tool makes car designs more aerodynamic

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.

When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: Lining up surprising behaviors of superconductor with one of the world's strongest magnets

Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...

Im Focus: World record: Fastest 3-D tomographic images at BESSY II

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.

Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
