How to treat involuntary eye movement with magnets

Magnets implanted behind the eye of a patient have been used to treat involuntary eye movements known as nystagmus, according to new research from the University College London (UCL) and the University of Oxford. The research team implanted a set of magnets in the eye socket beneath each eye in a patient who has nystagmus.

Macular degeneration recreated on a chip

Tohoku University researchers say they’ve recreated retinal diseases such as macular degeneration on a chip for disease modeling and drug screening. A research team from the Graduate Schools of Engineering and Medicine at Tohoku University cultured human retinal cells and vascular endothelial cells to replicate the outermost structure of the retina. Retinal cells exposed to

Stratasys 3D printing is speeding up vision diagnostic systems prototyping

Stratasys – the 3D printing and additive manufacturing solutions company – today announced that Italy-based surgical eye equipment maker Nidek Technologies is using a Stratasys Objet500 Connex3 multi-material color 3D printer to accelerate clinical trial evaluations of its ophthalmological devices (vision diagnostic systems). The R&D division has reported a 75% reduction in prototyping costs, while cutting

How deep learning algorithms could detect diabetic eye disease

Researchers at the Byers Eye Institute at Stanford University believe deep learning algorithms, a form of artificial intelligence, hold the key to detecting diabetic retinopathy and averting blindness in patients. Diabetic retinopathy damages the blood vessels at the back of the eye and is the leading cause of preventable blindness globally. Up to 45% of

6 visual impairment breakthroughs you need to know

About 285 million people have some form of visual impairment in the world, according to the World Health Organization. Of that number, 39 million are considered blind, and 246 million have low vision. Three-fifths of all vision impairment can be prevented or cured. Uncorrected refractive errors are one of the main causes of vision impairment in

These new electronic glasses allow the legally blind to see

Toronto-based eSight Corp. has launched a pair of electronic glasses that allow the legally blind to see. The eSight3 glasses use high-tech image processing to give those who are legally blind the chance to experience what it is like to have 20/20 vision. Users can control a variety of functions that are important for vision,

AGTC and Bionic Sight partner to cure blindness

Applied Genetic Technologies Corp. (AGTC) and Bionic Sight have announced their collaboration to develop an optogenetic therapy device for visual deficits and blindness. AGTC is a biotechnology company that conducts human clinical trials of adeno-associated virus-based gene therapies to treat rare diseases. Bionic Sight is an innovator in optogenetics and retinal coding. Those who have

HOYA Vision Care announces agreement to acquire safety prescription eyewear business from 3M

HOYA Vision Care, a division of HOYA Group (HOYA) announced a definitive agreement to acquire the safety prescription eyewear business of 3M. This safety prescription eyewear business is an industry leader with over 90 years experience in North America and provides HOYA with a comprehensive line of frames, prescription lenses and premium coating options in

Smartphone-based device could detect glaucoma

D-EYE, a developer of advanced devices for mass health screenings, is pleased to share findings from a study which shows that its groundbreaking portable imaging technology could play an important role in the detection of glaucoma. Glaucoma is a common age-related disease characterized by a buildup of pressure in the eye. If left undetected and

Parkinson’s could potentially be detected by an eye test

Researchers may have discovered a method of detecting changes in the eye which could identify Parkinson’s disease before its symptoms develop. Scientists at University College London (UCL) say their early animal tests could lead to a cheap and non-invasive way to spot the disease. Parkinson’s affects 1 in 500 people and is the second most common

Optical magnetic field sensor can detect signals from the nervous system

Quantum physics: The human body is controlled by electrical impulses, including the brain, the heart and nervous system. These electrical signals create tiny magnetic fields, which doctors could use to diagnose various diseases of the brain or heart in young foetuses. Researchers from the Niels Bohr Institute have now succeeded in developing a method for

Draper develops diagnostic method for macular degeneration

Approximately 15 million people over 60 years old in the United States suffer from vision loss due to age-related macular degeneration (AMD). Identifying the small subset of 10-15% of those patients who are experiencing Wet AMD, which involves fluid accumulating in the retina that can cause irreversible damage and blindness, is a difficult challenge. Clinicians

New technique for rapidly killing bacteria using tiny gold disks and light

Researchers have developed a new technique for killing bacteria in seconds using highly porous gold nanodisks and light, according to a study published in Optical Materials Express, a journal published by The Optical Society. The method could one day help hospitals treat some common infections without using antibiotics, which could help reduce the risk of
