Adaptive optics detect diabetes eye damage early

Indiana University professors Ann Elsner and Stephen Burns have developed an optic imaging method to detect the earliest stages of diabetic retinopathy. The device uses small mirrors to reflect light into the eye to overcome optical imperfections.  It detected damage spread widely across the retina in early disease states, including changes to blood vessels not thought to occur until the disease […]

Perceptual learning training improves vision

http://www.cell.com/current-biology/retrieve/pii/S0960982214000050 Professor Aaron Seitz, Professor Daniel Ozer , and Jenni Deveau at UC Riverside combined perceptual learning approaches to determine if improvements gained from an integrated, perceptual learning based training program would transfer to real world tasks. They found that  the brain-training technique significantly improved the vision of baseball players. Before the start of the 2013 NCAA Division 1 baseball season, 19 […]

Cancer cells glow when viewed through surgical glasses

https://news.wustl.edu/news/Pages/26496.aspx Washington University Professor Samuel Achilefu has developed surgical glasses that detect tumors by making cancer cells glow and appear blue in color.  This is accomplished through custom video technology, a head mounted display, and a targeted molecular agent that attaches to cancer cells.  Tumors as small as 1 mm in diameter could be detected. […]

Smart holograms diagnose and monitor medical conditions

http://www.cam.ac.uk/research/news/holographic-diagnostics-0 Cambridge researchers are developing responsive, color-changing diagnostic holograms.  Silver nanoparticles are formed into three dimensional holograms of predetermined shapes in a fraction of a second using a single laser pulse.  They will be used for portable medical tests and devices, to monitor diabetes, cardiac function, infections, electrolyte or hormone imbalance easily,inexpensively, and non-invasively. The […]

Miniature 3D sensor maps surgical field; scope small enough for use in neurosurgery

http://www.visionsense.com/hp.html Visionsense’s miniature 3D sensor optically maps the surgical field, based on (and imitating) the eye of a bee. A single sensor is divided into hundreds of thousands of tiny “eyes” looking in different directions, using an array of micron-sized elements.  The elemental information is translated into left and right eye images, resulting in a […]

Brain processes images viewed for 13 milliseconds

http://web.mit.edu/newsoffice/2014/in-the-blink-of-an-eye-0116.html MIT professor Mary Potter has published a study showing that the human brain is capable of processing images viewed through the eyes for 13 milliseconds. This is significantly faster than the 100 milliseconds reported in earlier research. The study offers evidence that “feedforward processing” — the flow of information in only one direction, from retina through […]

Smart contact lens with potential to monitor intraocular pressure

http://www.nature.com/ncomms/2014/140107/ncomms3982/full/ncomms3982.html Swiss Federal Institute of Technology scientists have developed a light, flexible, ultra-thin membrane with the potential to detect intraocular pressure in glaucoma.  Researchers claim that the technology “could offer significant advantages over existing solutions in terms of thickness, lightness, and transparency and, hence, comfort for the patient.” The device consists of layered polymer films, one […]
