Ophthalmology News and Research

RSS

Ophthalmology is the specialized field of medicine that focuses on the health of the eye. It includes the anatomy, physiology and diseases that may affect the eye. Historically, the science of ophthalmology encompassed all aspects of visual function, both in health and in illness. Additionally, ophthalmology also includes animal eyes as ocular function and optic diseases are similar among humans and animals.

Risk of blindness from spinal-fusion surgery has declined, study shows

The risk of blindness caused by spinal fusion, one of the most common surgeries performed in the U.S., has dropped almost three-fold since the late 1990s, according to the largest study of the topic to date.

New technique can help identify aggressive forms of DCIS

When a woman is diagnosed with the earliest stage of breast cancer, how aggressive should her treatment be? Will the non-invasive cancer become invasive? Or is it a slow-growing variety that will likely never be harmful?

Researchers develop 2D culture system that mimics development of the whole eye

Research groups led by Professor Kohji Nishida of the Department of Ophthalmology and Endowed Associate Professor Ryuhei Hayashi of the Department of Stem Cells and Applied Medicine, Osaka University Graduate School of Medicine, developed a 2D culture system which mimics the development of the whole eye by promoting cell-autonomous differentiation of human iPS cells.

New AAV 3.0 program to create next-generation viral vectors for better treatment of inherited diseases

The Perelman School of Medicine at the University of Pennsylvania has launched a new program, called AAV 3.0, to create new viral vectors to find quicker and better treatments for an array of diseases. James M. Wilson, MD, PhD, a professor of Medicine and director of the Orphan Disease Center, will lead an interdisciplinary team of over 30 scientists to create this new technology platform with support provided by the University of Pennsylvania Health System.

Researchers identify exact origin of 2009 swine H1N1 flu pandemic

The 2009 swine H1N1 flu pandemic — responsible for more than 17,000 deaths worldwide — originated in pigs from a very small region in central Mexico, a research team headed by investigators at the Icahn School of Medicine at Mount Sinai is reporting.

Study estimates real-world prevalence of myopic choroidal neovascularization in the U.S.

A new study estimates that 9.6 million adults in the United States are highly myopic, or severely nearsighted. Of those, nearly 820,000 have a degenerative form of the disease and more than 41,000 suffer a complication called myopic choroidal neovascularization that could cause long-term vision loss, with women at higher risk.

Delayed healing linked to weaker electrical currents in diabetic wounds

People with diabetes often suffer from wounds that are slow to heal and can lead to ulcers, gangrene and amputation. New research from an international group led by Min Zhao, professor of ophthalmology and of dermatology at the University of California, Davis, shows that, in animal models of diabetes, slow healing is associated with weaker electrical currents in wounds.

Study shows for-profit hospices have persistently high rates of hospitalization

Patients who were asked where they wanted to die upon entering hospice had lower rates of hospitalization at the end of life, as did those in hospices that monitored symptoms more frequently, according to a new study led by researchers at the Icahn School of Medicine at Mount Sinai.

Darapladib drug can protect against vision loss in diabetic patients

Researchers at Queen's University Belfast and University College London have discovered that a drug, originally developed to treat cardiovascular disease, has the potential to reduce diabetes related blindness.

Controlling corneal blindness by 2030: an interview with Dr Pravin Vaddavalli

Corneal blindness is estimated to be the second most prevalent cause of blindness in many less developed countries. Globally, bilateral corneal blindness is estimated to afflict 4.9 million persons and accounts for 12% of 39 million blind, utilizing WHO 2010 global blindness data.

Study captures interactions of HIV-infected immune cells in living animal

By watching brightly glowing HIV-infected immune cells move within mice, researchers at the Icahn School of Medicine at Mount Sinai have shown how infected immune cells latch onto an uninfected sister cell to directly transmit newly minted viral particles.

Researchers explore how ALS develops from muscle perspective

In an effort to better understand what happens during Amyotrophic Lateral Sclerosis (ALS), researchers at Umea University in Sweden have compared the impact of ALS on the eye and limb muscles.

Study reinforces significance of raising young children in stimulating environments

A recent study shows that infants and toddlers take longer to notice new visual stimuli and are less accurate in their gaze than adults, but slowly improve as they age. The findings reinforce the importance of raising young children in stimulating environments, and set an important baseline as detection of developmental disorders increasingly rely on tracking eye movements.

Zika virus infection may cause ocular problems in Brazilian infants with microcephaly

Researchers studying babies with a Zika virus-related birth defect say they have found previously unreported eye problems possibly linked to the virus that could result in severe visual impairment.

NIH-funded study finds visual impairment, blindness may double by 2050

With the youngest of the baby boomers hitting 65 by 2029, the number of people with visual impairment or blindness in the United States is expected to double to more than 8 million by 2050, according to projections based on the most recent census data and from studies funded by the National Eye Institute, part of the National Institutes of Health.

CSU researchers develop colorful potatoes that are high in antioxidants, rich in nutrients

Purple potatoes might not be the first thing that comes to mind when trying to increase vitamin, mineral and antioxidant intake. However, a group of researchers from Colorado State University have recently developed potato varieties that satisfy these nutritional needs and could act as a preventive measure to several diseases.

Research provides pathway toward creation of first broad-spectrum antiviral drug

By studying the rare person -- about one in a million -- who can fight off viral infections more effectively than everyone else, investigators at the Icahn School of Medicine at Mount Sinai have developed a strategy to help the rest of us achieve this enhanced anti-viral state.

Researchers use high-power prisms to design new eyeglasses to expand visual fields of hemianopia patients

Researchers from the Schepens Eye Research Institute of Massachusetts Eye and Ear and Harvard Medical School have designed three new eyeglasses using high-power prisms to optimally expand the visual fields of patients with hemianopia, a condition in which the visual fields of both eyes are cut by half.

Serum biomarkers can help predict risk of IBD development and complications

Years before inflammatory bowel disease (IBD) is diagnosed and symptoms exist, biomarkers are already circulating that can help predict risk not only of disease development but also of complications, according to research published online last week, which will also appear in the June 15th print issue of Alimentary Pharmacology & Therapeutics.

New eye scan may detect onset of Alzheimer's disease

Early structural changes in the back of the eye — now visible with a newly developed eye scan — may indicate the onset of Alzheimer's disease. The research is being presented at the 2016 Annual Meeting of the Association for Research in Vision and Ophthalmology this week in Seattle, Wash.
