Bionic eye helping patients with retinitis pigmentosa After more than two decades of field work, the first bionic eye for the blind is finally available. It is call the Argus II Retinal Prosthesis System (“Argus II”) and is used to treat patients with late stage retinitis pigmentosa (RP). The system involves implanting a small electronic device in and around the eye. It also uses a tiny video camera attached to a pair of glasses and a video processing unit that is worn or carried by the per...
Phone technology may play dramatic new role in health care In the next 12 months, doctors will be able to make house calls where they diagnose and treat the patients on the spot using their phones. Researchers and physicians in the field are about to start running on-the-spot tests for environmental toxins, medical diagnostics, food safety and more with their smartphones. University of Illinois researchers have developed a cradle and app for the iPhone that uses the phone’s built-in camera and p...
Detecting Alzheimer’s disease in its earliest stages Australian scientists say they now are much closer to developing a screening test for the early detection of Alzheimer’s disease. The investigators have identified blood-based biological markers that are associated with the build-up of amyloid beta, a toxic protein in the brain. This plaque build-up develops years before symptoms appear and irreversible brain damage has occurred. “Early detection is critical, giving those at risk a much bette...
Wearing a contact lens at night may help restore age-related loss of near vision It may be possible to get rid of your reading glasses. Many older adults have age-related declines in near vision (presbyopia) requiring bifocals or reading glasses. Now, a newly emerging technique called hyperopic orthokeratology (OK) may provide an alternative for restoring near vision without the need for glasses. Researchers have just completed a small study showing that wearing OK contact lenses overnight can...
New magnetic approach to treating heartburn It may be possible to replace your daily stomach medicine with a new magnetic device. It is called the LINX system and is composed of a series of titanium beads, each with a magnetic core. The beads are connected to form a ring shape and then implanted at the lower esophageal sphincter (LES), a circular band of muscle that closes the last few centimeters of the esophagus. The LES prevents the backward flow of stomach contents. This new medical device...
