In early January, researchers from the Massachusetts Institute of technology (MIT) announced in Biomedical Optics Express about the development of their innovative ophthalmic devices for the primary examination of patients. Innovative medical device able to diagnose the disease the eye, just by being taken in hand. Tool, a portable video camera, looking at the whole retina of a patient in seconds, and can assist the primary care physicians in the early detection of weight-related diseases of the retina, including diabetic retinopathy, glaucoma and macular degeneration.
Although other research groups and companies have already previously created portable devices based on similar technology, new equipment design from MIT was able to unite advanced technologies, such as ultramicroelectrodes 3D display and a tiny mirror with microelectromechanical systems (MEMS). These innovations should enable clinicians to collect comprehensive data about the condition of the retina in just one measurement.
Usually, to diagnose diseases of the retina, the ophthalmologist or optometrist should examine the patient in his own office, usually with the use of specialized desktop tools. However, not many people regularly visit these professionals. To improve public access to eye care, the MIT group, in collaboration with the University of Erlangen and Praevium/Thorlabs has developed a portable tool that can be used even without the presence of an ophthalmologist.
The instrument uses the technique of optical imaging sequence (OCT). Infrared light is projected into the eye and onto the retina. Gradient echo is returned to the apparatus, which uses interferometry to detect the time delay, as well as private displays tissue structure of the retina like display of ultrasound or radar. In order to compensate for the instability of the portable handheld device, the tool uses multiple 3D images.
