Researchers discover cause, develop pharmacological treatment for reducing retinitis pigmentosa vision loss

Researchers from the University of California, Irvine have discovered that the absence of Adiponectin receptor 1 protein (AdipoR1), one of the principal enzymes regulating ceramide homeostasis in the retina, leads to an accumulation ...


Improved retinal transplant technique ready for clinical trials

Researchers led by Michiko Mandai at the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan have used a genetic modification to improve human-derived retina transplants grown in the lab. After transplant into damaged ...


New data on drug metabolism and distribution in the eye

Severe visual illnesses are increasing in our society, and effective treatments are missing for diseases as age-related macular degeneration, diabetic retinopathy, and glaucoma. Both industry and academia are highly interested ...


Using the eye as a window into heart disease

Scientists have developed an artificial intelligence (AI) system that can analyze eye scans taken during a routine visit to an optician or eye clinic and identify patients at a high risk of a heart attack. 


High-tech eye drop research targets corneal damage

New research has laid the groundwork for a long-lasting eye drop to treat corneal neovascularisation (CoNV), a condition which affects more than a million people globally each year.


Promising new treatment for dry eye disease

The University of Manchester, Seoul National University College of Medicine and Link Biologics Limited today announced that promising preclinical data on the treatment of dry eye disease using a novel protein biological drug, ...


An imaging device for seeing the biochemistry of vision

The biochemistry of vision is a complex process. The molecules supporting the visual pigments that allow us to see our surrounding reality have remained essentially invisible for scientists for a long time. The team led by ...


Eye model may improve corneal transplantation

About 600 corneal transplantations are performed in Denmark every year. Most of them are performed as treatment of the eye disease "Fuchs endothelial dystrophy," which causes cellular layers on the back of the cornea to become ...


Vision tech developments give a glimpse of the future

Advances in assistive technology have removed many access barriers for people with vision loss. But it's the development of visual prosthesis that has the potential to offer a whole new way of 'seeing' the world.

Alzheimer's disease & dementia

Cataract surgery linked with lessened dementia risk: study

Cataracts affect most older adults at risk for dementia, and now researchers are finding strong evidence that cataract surgery is associated with a lower risk of developing dementia.


Seeing and hearing: How they interplay in the brain

As it is common experience, our senses do not work in complete isolation from the others: sight helps listening (and this is maybe why it is difficult to understand people when they speak with their mask on) but can also ...


Biocompatible glue for corneal repair

A biocompatible, antimicrobial adhesive for corneal repair and grafting could replace sutures and conventional adhesives with bad side effects.


HyVIS: Hybrid synapses to treat retinal dystrophies

HyVIS, the European project coordinated by the IIT-Istituto Italiano di Tecnologia (Italian Institute of Technology), is about to start. By combining nanotechnology and optics, it will develop bionic synapses for retinal ...


Bionic eye study paves the way toward human trials

A bionic eye being developed by a team of biomedical researchers at the University of Sydney and UNSW has shown to be safe and stable for long-term implantation in a three-month study, paving the way towards human trials.


'Exercise in a pill' could offer solution for at-risk people

Researchers from The Australian National University (ANU) have identified unique molecular signals in the body that could hold the key to developing a supplement capable of administering the health benefits of exercise to ...


First patient fitted with 3D-printed eye

A 3D-printed eye is a true biomimic and a more realistic prosthetic, with clearer definition and real depth to the pupil. Unlike traditional methods, it is made using digital scans of the eye instead of an invasive mold of ...


Brief period of 'blindness' is essential for vision

Fixational eye movements are tiny movements of the eye—so small we humans aren't even aware of them. Yet they play a large role in our ability to see letters, numbers, and objects at a distance.

Growing evidence links pentosan polysulfate sodium, maculopathy

(HealthDay)—There is growing evidence that pentosan polysulfate sodium (PPS) is associated with an increased risk for maculopathy, according to a study published online Nov. 18 in JAMA Ophthalmology.


Map of mouse iris offers new look at the eye

If vision science were a movie, the iris would be a supporting actor. It doesn't get as much limelight as the retina, the eye's light-sensing tissue. And it's not as high-profile as the lens, which can cloud with cataracts ...

Alterations caused by ALS detected in the retina

Amyotrophic lateral sclerosis (ALS), characterised by harm to brain neurons and to the spinal cord, also affects the tissue of the retina, according to a study headed up by Universidad Complutense de Madrid (UCM).


New research shows virtual school can harm children's vision

When COVID-19 first shut down classrooms and virtual schooling became the new norm, ophthalmologists predicted an increase in digital eye strain in children. New research from ophthalmologists at Wills Eye Hospital confirms ...


Smoking, alcohol intake tied to age-related macular degeneration

(HealthDay)—Genetically predicted smoking initiation and lifetime smoking are associated with elevated risk of advanced age-related macular degeneration (AMD), while genetically predicted alcohol intake is associated with ...
