Researchers at MIT have developed a cheap and easy to use system, called Catra, that uses a cameraphone clip-on device to map out cataracts.
The technology functions by sweeping the eye with a beam of light and using the phone’s camera to detect fuzzy spots. It can provide both a map of the cataracts and maybe help make an overall assessment of whether surgery might be necessary.
Oxford University is touting the work of its researchers who are building a special set of electronic glasses that may help people with all sorts of vision conditions. Cameras in the frame would analyze the scene ahead and active glass would display important things either in a different part of the frame of view or interpret it with colors, brightness, and basic representations. The idea is being profiled at the Royal Society Summer Science Exhibition where visitors get to see how the system would function.

Diabetic retinopathy is a complication of diabetes mellitus that can eventually lead to blindness. Current treatments are not the terribly effective or reliable. For example, drugs in the form of eye drops often have a lower than desirable rate of diffusion into the eye, as well as potential systemic side effects. And, for obvious reasons, most patients aren’t too fond of the more direct needle in the eye approach.
At the University of British Columbia, researchers have developed a novel device that will make drug treatment for diabetic retinopathy safer and more effective. The device, no larger than the head of a pin, consists of a sealed reservoir made of flexible polydimethylsiloxane that is implanted behind the eye. Part of the reservoir’s flexible membrane is magnetic; an electric field applied to the device causes the magnetic membrane to deform and release a controlled amount of drug out of a small hole, much in the same way water is released from a plastic bottle when it’s squeezed.
Researchers from Luleå University of Technology in Sweden are developing a wheelchair that senses its environment in 3D and transmits this information to its user. It features a laser scanner that uses a time-of-flight technique to map its surroundings in 3D. A haptic robot, held in the left hand, translates this data to useful information for the user, enabling one to feel obstacles, essentially acting as a virtual white cane. A joystick is used with the right hand for steering.

Keratoconjunctivitis sicca, better known as “dry eye”, is an annoying and sometimes painful condition in which the eyes often itch and burn because a person cannot produce sufficient tears to bathe and cool the eyes. Ophthalmologists usually diagnose dry eye through a series of tests that often analyze the tear fluid and its interaction with the surface of the eye, but environmental conditions such as ambient humidity and temperature can skew the results.

Most kids, many pediatricians, and the occasional Medgadget editor would relish any opportunity to utilize video games to improve health. Microsoft’s Kinect sensor has been featured here on Medgadget numerous times for its medical applications in imaging and gesture controls. The Nintendo Wii was one of the first systems to exercise more than your fingers.

Second Sight Medical of Sylmar, California has received European approval for its bionic eye system that can bring a modicum of sight to people with advanced retinal degenerative diseases. The Argus II system uses a head worn video camera to capture the scene, processes it by a computer, and sends a signal to an implant that stimulates the retina’s still functioning cells. Although the resulting sight is nowhere near normal, it is nevertheless a major improvement on total blindness.

French startup E(ye)Brain, in collaboration with neurologists at La Pitié-Salpêtrière Hospital in Paris, has been working on a video-oculography measurement technology for early diagnosis of neurological diseases. The company has recently announced that its Mobile Eye Brain Tracker will soon be hitting the market, probably in Europe and elsewhere, except for the United States where no FDA clearance has been given to the device. The company hopes that its technology will be validated for early diagnosis in a range of disorders, such as progressive supranuclear palsy, corticobasal degeneration, multiple sclerosis, and even Parkinson’s.

CSEM (Centre Suisse d’Electronique et de Microtechnique) has joined Israel’s Rainbow Medical and Zyvex Labs in their Nano Retina joint venture to develope a retinal prosthesis. The tiny Bio-Retina would be implanted in a minimally invasive procedure and the development team believes that return of sight would be immediate, save for a week of traditional post procedure recovery.
