Cause of destructive cascade of diabetic retinopathy
The retina can be bombarded by reactive oxygen species in diabetes, prompting events that destroy healthy blood vessels, form leaky new ones and ruin vision.Now researchers have learned that those chemically reactive molecules must come from both the b…
Stem cell replacement for frequent age-related blindness
Age-related macular degeneration (AMD) is the most frequent cause of blindness. Scientists at the Department of Ophthalmology at the Bonn University Hospital and from the Neural Stem Cell Institute in New York (USA) have developed a method for using st…
FDA approves first gel for sealing corneal incision after cataract surgery
The U.S. Food and Drug Administration has approved the first gel sealant for use in stopping fluid from leaking through the incision in a patient’s cornea after cataract surgery with intraocular lens placement in adults. Prior to today’s approval, stit…
Pilot study for the first implantable, permanent intraocular pressure sensor for glaucoma patients successfully completed
Implandata Ophthalmic Products GmbH (Implandata) has successfully completed its ARGOS-01 pilot study for the first implantable, permanent intraocular pressure sensor. Implant safety and functionality has been demonstrated in this study. In addition imp…
Aflibercept in macular oedema: added benefit not proven
Neither the new drug nor the comparator therapy was used in accordance with their approvals in the studiesFor the third time in one year, the German Institute for Quality and Efficiency in Health Care (IQWiG) dealt with the drug aflibercept.
Residual activity ‘hot spots’ in the brain key for vision recovery in stroke patients
Scientists know that vision restoration training (VRT) can help patients who have lost part of their vision due to glaucoma, optic nerve damage, or stroke regain some of their lost visual functions, but they do not understand what factors determine how…
Insight into likelihood of retinal detachment following open globe injury
Ocular trauma causing open globe injury, or a breach in the wall of the eye, remains an important cause of vision loss, with more than 200,000 open globe injuries occurring worldwide each year. In many cases, retinal detachment follows the traumatic in…
‘Quit smoking to cut risk of impaired vision’
In a large study of Swedish men, further evidence has emerged of the smoking link to cataract development in the eye, with addiction to 15 cigarettes a day raising the risk of needing a cataract operation by 42%, compared with people who have never smo…
New technique could boost corneal transplant acceptance rates
New research from the University of Texas Southwestern Medical Center at Dallas has detailed a new technique that may be able to boost patients’ acceptance rates of corneal transplants. This is according to a study published in the American Journal of …
Regular eye exams key to preventing vision loss from glaucoma
Glaucoma is a group of eye diseases that can damage the optic nerve. This nerve carries images from the retina – specialized light-sensing tissue – to the brain, which allows you to see. If left untreated, glaucoma can result in loss of vision and even…
New hand-held optical device to catch early signs of retinal disease
A new optical device puts the power to detect eye disease in the palm of a hand. The tool – about the size of a hand-held video camera – scans a patient’s entire retina in seconds and could aid primary care physicians in the early detection of a host o…
All in the eyes: corneal reflections in photos can help solve crimes
The eyes are not just the mirror of the soul, they also mirror the world around us. Now, a UK team has found that today’s high-resolution digital images are now so detailed, they can enlarge the eyes in people’s photos and retrieve images of out-of-sho…
Association between angiogenic factor secretion by melanocytesa and pigmentation leve
The decreased vision loss that accompanies age-related macular degeneration (AMD) is associated with abnormal blood vessel growth in the eye. Frequencies of AMD development are different among racial backgrounds, with occurrence of AMD highest among in…
Success in mouse model of aniridia is first instance of drug reversing a congenital deformity
University of British Columbia and Vancouver Coastal Health scientists have developed a potential cure for a rare eye disease, showing for the first time that a drug can repair a birth defect.
For the first time cells from the eye are inkjet printed
A group of researchers from the UK have used inkjet printing technology to successfully print cells taken from the eye for the very first time.
The brain’s data compression mechanisms
Researchers have hitherto assumed that information supplied by the sense of sight was transmitted almost in its entirety from its entry point to higher brain areas, across which visual sensation is generated.
Diabetic macular edema: ‘not enough awareness and patient care’
Individuals with diabetes have a significantly higher risk of developing diabetic eye disease. But new research reveals that less than 50% of US adults with diabetic macular edema – retina swelling that can lead to blindness – are told by their doctor …
Intermittent vision of the action can improve brain’s visual perception, improve hockey players’ performance
Professional hockey players who trained with special eyewear that only allowed them to see action intermittently showed significant improvement in practice drills, according to a Duke University study with the NHL’s Carolina Hurricanes.
Partially blocking blood vessels’ energy source may stop cancer growth, blindness & other conditions
Inhibiting the formation of new blood vessels is a common strategy for treating a range of conditions such as cancer, inflammatory diseases, and age-related macular degeneration. Unfortunately, drug inefficiency, resistance, and relapse have limited th…
