Singapore researchers develop a bio-functional thermogel to prevent retinal scarring

Singapore scientists have developed a bio-functional thermogel, a type of synthetic polymer, to prevent retinal scarring caused by failed retinal detachment repair surgery.

Roundworms shed light on vision loss in a rare human genetic disorder

In this interview, News-Medical speaks to Xinxing Zhang, a postdoctoral research fellow at the University of Michigan, about his research investigating vision loss in Bardet-Biedl syndrome.

Proteins in the eye may predict which macular degeneration patients need life-long treatment

In a study of eye fluid from 38 patients, Johns Hopkins Medicine researchers say they have found that levels of a specific protein appears to help accurately predict whether people with the wet form of age-related macular degeneration may need lifelong, frequent eye injections to preserve vision or if they can be safely weaned off the treatments.

Study: Glaucoma diagnosis not associated with steeper rates of cognitive decline

Previous studies have looked for links between glaucoma-;a neurodegenerative disorder that's the leading cause of irreversible blindness-;and cognitive function, but they've generated mixed results.

Specific retinal cell appears to be good at housing Ebola and other viruses

A specific cell within our retina, the light-sensitive part of our eyes responsible for sending visual information to our brain, appears to be particularly good at housing Ebola and other viruses, new research has found.

New discovery could lead to the development of therapeutic approaches for retinitis pigmentosa

Retinitis pigmentosa, a degenerative genetic disease of the eye, is characterized by progressive vision loss, usually leading to blindness.

New disease that affects the macula discovered

Researchers from the National Eye Institute have identified a new disease that affects the macula, a small part of the light-sensing retina needed for sharp, central vision.

Detailed genetic roadmap of glaucoma will help develop new drugs to combat the disease

A new, detailed genetic roadmap of glaucoma – the world's leading cause of irreversible blindness – will help researchers develop new drugs to combat the disease, by identifying potential target areas to stall or reverse vision loss.

Dietary supplements can slow progression of age-related macular degeneration, NIH study confirms

The Age-Related Eye Disease Studies (AREDS and AREDS2) established that dietary supplements can slow progression of age-related macular degeneration (AMD), the most common cause of blindness in older Americans. In a new report, scientists analyzed 10 years of AREDS2 data.

Gene therapy for degenerative retinal disease has no safety concerns but fails to improve vision loss

A 28-patient phase 1 gene therapy clinical trial for the degenerative retinal disease Leber hereditary optic neuropathy (LHON) found no significant safety concerns; however, treatment failed to improve or slow vision loss, with even the highest dose. LHON affects the optic nerve, which carries visual signals from the light-sensing retina to the brain.

Study highlights the positive effects of Humanin G in reducing inflammation in AMD

A new research paper was published in Aging (Aging-US) on the cover of Volume 14, Issue 10, entitled, "Effect of Humanin G (HNG) on inflammation in age-related macular degeneration (AMD)."

Scientists discover a new role for protein complex at the center of Bardet-Biedl syndrome

Scientists have identified a new role for a protein complex at the center of a human genetic disorder called Bardet-Biedl syndrome, or BBS, for which there is currently no cure.

New drug inhibits growth of the most aggressive meningiomas

When a specific non-metastatic brain tumor — a meningioma — recurs after surgery and radiation treatment, a patient is normally out of options. No drugs are approved for these aggressive tumors, which occur in up to 20 percent of cases and can lead to patient disability or even death.

Ocular toxoplasmosis found to be common among Australians

One in 150 Australians have retinal scars caused by the Toxoplasma parasite, according to new Flinders University analysis.

Poor vision in older adults often mistakenly conflated with mild cognitive impairment

Millions of older people with poor vision are at risk of being misdiagnosed with mild cognitive impairments, according to a new study by the University of South Australia.

Single-cell-resolution map of retinal pigment epithelium could help develop precise therapies for degenerative diseases

Researchers have identified distinct differences among the cells comprising a tissue in the retina that is vital to human visual perception.

Hearing and vision impairment found to be independently associated with cognitive decline

A new nationally representative study published online in the Journal of Alzheimer's Disease Reports found hearing impairment and vision impairment to be independently associated with cognitive impairment.

Treatment for retinal vein occlusion yields long-lasting vision gains, study shows

New research shows that a treatment for retinal vein occlusion yields long-lasting vision gains, with visual acuity remaining significantly above baseline at five years.

Study shows significant increase in survival rates of extremely pre-term babies

A new study co-authored by a University of Rochester Medical Center researcher has found that the survival rates of extremely pre-term babies has increased significantly in the past decade.

Discovery provides a more precise picture of the retina's optical properties

Researchers at the National Eye Institute (NEI) have discovered that power-producing organelles in the eye's photoreceptor cells, called mitochondria, function as microlenses that help channel light to these cells' outer segments where it's converted into nerve signals.
