Improved optical imaging technique can help identify patients at risk of future heart attacks

Doctors need better ways to detect and monitor heart disease, the leading cause of death in industrialized countries. A team led by Massachusetts General Hospital researchers with support from the National Institute of Biomedical Imaging and Bioengineering has developed an improved optical imaging technique that found differences between potentially life-threatening coronary plaques and those posing less imminent danger for patients with coronary artery disease.

Air pollution associated with greater risk of glaucoma

Living in a more polluted area is associated with a greater likelihood of having glaucoma, a debilitating eye condition that can cause blindness, finds a new UCL-led study in the UK.

Researchers identify genes linked to most severe symptoms of multiple sclerosis

In a bid to determine factors linked to the most debilitating forms of multiple sclerosis, Johns Hopkins Medicine researchers say they have identified three so-called "complement system" genes that appear to play a role in MS-caused vision loss.

Discontinuing popular over-the-counter vitamin can lead of reversal of retinal swelling

In a first-of-its-kind clinical report, retina specialists at the New York Eye and Ear Infirmary of Mount Sinai have shown that severe vision loss from a self-prescribed high dose of over-the-counter niacin is linked to injury of a specific cell type in a patient's eye.

The ear's sensitivity to sound is controlled by outer hair cells

The human inner ear has a type of cell called the outer hair cell. These were thought to amplify sounds from the environment. However, a new study based on hearing in gerbils shows these cells are probably involved in regulating the sensitivity of the ear to sound. This could help find ways to preserve good hearing by protecting these cells from destruction.

Ear's tiny outer hair cells regulate sound sensitivity, study shows

The ear’s tiny outer hair cells adjust the sensitivity of neighboring inner hair cells to sound levels rather than acting like an amplifier, suggests a new study published today in eLife.

QUT researchers use deep learning methods for more accurate eye testing

Queensland University of Technology researchers have applied artificial intelligence deep learning techniques to develop a more accurate and detailed method for analyzing images of the back of the eye to help clinicians better detect and track eye diseases, such as glaucoma and age-related macular degeneration.

Researchers identify changes in retinal layers of patients with mild Alzheimer's disease

Researchers at the Complutense University of Madrid have identified changes in retinal layer thickness, inflammation or thinning in patients with mild Alzheimer's disease, confirming that the retina is one of the most important biomarkers for early diagnosis of the disease.

'MasSpec Pen' could help distinguish between cancerous and healthy tissue during surgery

A major challenge for cancer surgeons is to determine exactly where a tumor starts and where it ends. Removing too much tissue can impair normal functions, but not taking enough can mean the disease could recur.

Simple, minimally-invasive tool to study nasal airways of cystic fibrosis patients

A paper published today in Science Translational Medicine describes a simple, minimally invasive new tool for viewing differences in the nasal airways of cystic fibrosis patients in vivo at a cellular level.

Low-cost OCT scanner promises to bring vision-saving technology to underserved regions

Biomedical engineers at Duke University have developed a low-cost, portable optical coherence tomography scanner that promises to bring the vision-saving technology to underserved regions throughout the United States and abroad.

Augusta vision scientist receives grant to learn more about keratoconus’ causes and treatments

It's an eye condition where genetics and environmental factors like ultraviolet light and vigorous eye rubbing conspire to make the usual curvature of the cornea more pointy, leaving us with double vision and nearsighted.

New objective model classifies degrees of iridocorneal angle to assess severity of glaucoma

Pablo Amil, a researcher from the research group in Nonlinear Dynamics, Nonlinear Optics and Lasers (DNOLL) at the ESEIAAT, has created an objective model that classifies the degrees of the iridocorneal angle, a key element for assessing the severity of glaucoma.

New 'virtual biopsy' device developed to detect skin tumors

Using sound vibrations and pulses of near-infrared light, a Rutgers University scientist has developed a new "virtual biopsy" device that can quickly determine a skin lesion's depth and potential malignancy without using a scalpel.

Expert consensus published on use of imaging for precise diagnosis of heart attack

Imaging provides a more precise diagnosis of a heart attack that can be used to individualize treatment. That's the main message of an expert consensus paper published today in European Heart Journal, a journal of the European Society of Cardiology, and presented at EuroPCR in Paris, France.

Imaging beyond routine angiography may be helpful in women with suspected MI and no obstructive CAD

A subset of women referred to the cardiac catheterization lab for suspected myocardial infarction thought to be due to a culprit artery are found to have no obstructive coronary artery disease by angiography.

New imaging technology will improve understanding of embryonic development

Soon after conception, an embryo's circulatory system connects to that of its mother. Complications that occur at this critical time can result in miscarriage or birth defects with long-term chronic conditions.

Developing imaging techniques for early detection of eye and brain diseases

The eyes may be the window to the soul, but to scientists, they are also the window to the brain. In particular, the retina, a delicate light-sensing neural network with specialized cells at the back of the eyeball, is linked directly to the brain via the optic nerve and is considered by some to be part of the brain itself.

Alzheimer’s and brain health could soon be detected using an eye exam

Soon, an eye examination may be all that is needed to confirm a diagnosis of Alzheimer's disease, according to researchers at Duke's Health.
