Bioabsorbable stents show promise

A study published online in The Lancet presented two year data for the bioabsorbable everolimus coronary stent.

Shining light on diabetic retinopathy

A group of scientists in California is trying to develop a cheaper, less invasive way to spot the early stages of retinal damage from diabetic retinopathy, the leading cause of blindness in American adults, before it leads to blindness.

Optical frequency-domain imaging provides 3-D view of human coronary arteries

For the first time researchers are getting a detailed look at the interior of human coronary arteries, using an optical imaging technique developed at the Wellman Center for Photomedicine at Massachusetts General Hospital (MGH).

New technique sees into tissue at greater depth, resolution

By coupling a kicked-up version of microscopy with gold nanoparticles, investigators at Duke University have been able to peer so deeply into living tissue that they can see molecules interacting.

Research targets diabetes-related eye conditions

World Diabetes Day is on 14 November this year highlighting that diabetes is on the increase and to create awareness to aid prevention of figures growing larger. To help prevent diabetes becoming a burden to the NHS resources in the future, new research projects commissioned by the National Institute for Health Research's Health Technology Assessment (NIHR HTA) programme will evaluate the effectiveness and cost-effectiveness of different screening tests used in diabetic eye care.

Vulnerable plaque may be easier to detect through optical coherence tomography

Research results indicate that optical coherence tomography (OCT), a newly evolving imaging method, may be the best tool available to detect vulnerable plaque in coronary arteries. The findings will be presented at the 20th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, sponsored by the Cardiovascular Research Foundation (CRF).

Optical coherence tomography helps track multiple sclerosis

A five-minute eye exam might prove to be an inexpensive and effective way to gauge and track the debilitating neurological disease multiple sclerosis, potentially complementing costly magnetic resonance imaging to detect brain shrinkage - a characteristic of the disease's progression.

Near-infrared resonant nanoshells for combined optical imaging and photothermal cancer therapy

Using metal nanoshells designed to both absorb and scatter near-infrared light, a team of investigators at Rice University has shown that such nanoparticles can both image and treat tumors in animals. Their experiments revealed complete tumor destruction in more than 80 percent of animals treated with these nanoshells.

Researchers find cure for dogs with sudden acquired retinal degeneration syndrome

If two dogs are any indication, Iowa State University veterinary researchers may have found a cure for a previously incurable disease that causes dogs to go blind suddenly.

New type of laser for providing high-resolution 3-D images of the retina

In efforts that may improve diagnoses of many eye diseases, researchers will introduce a new type of laser for providing high-resolution 3-D images of the retina, the part of the eye that converts light to electrical signals that travel to the brain.

University of Kent spin out to revolutionise biomedical optics

Kent Enterprise and the School of Physical Sciences at the University of Kent have 'spun out' a high-tech company that is set to revolutionise biomedical optics.

Yellow pigment that sits on the retina focus of macular degeneration research

Whether a tiny yellow pigment is the main thing standing between many older people and macular degeneration is under study at the Medical College of Georgia.

Using light under your skin

You have a tiny wound on your hand that doesn’t heal, a bad burn on your chest – or an injured retina. Your doctor cannot tell how serious the injuries are below the surface. He needs tissue samples. That means using a scalpel, which again equals pain, perhaps even a risk. Soon there may be hope for an improved and totally harmless method to peer under the surface of the skin: light.

Optical coherence tomography (OCT) can successfully identify the characteristics of coronary plaques

A catheter-based imaging technology called optical coherence tomography (OCT) can successfully identify the characteristics of coronary plaques in patients with various cardiac symptoms. The report from researchers at Massachusetts General Hospital (MGH) will appear in the journal Circulation.

Oak Ridge technology used to understand semiconductor defects helps people at risk of becoming blind

Millions of people at risk of becoming blind could one day be helped by an Oak Ridge National Laboratory technology originally intended to understand semiconductor defects.

A unique new non-invasive technique for high resolution optical imaging of the eye

The technique, pioneered by the University of Kent, is funded by the Toronto-based company, Ophthalmic Technology Inc (OTI). The University’s Applied Optics Group is currently working with university hospitals in New York (USA), Osaka (Japan), Asahikawa (Japan), Amsterdam (Netherlands) and Milan (Italy) to carry out preliminary clinical trials.
