Scienctists' network
Stimulus grant establishes 'Facebook for scientists'
Nov. 4,
2009 -- The School of Medicine will be one of seven institutions creating a new national network for sharing information between scientists. A $12.2 million grant from National Center for Research Resources (NCRR) will establish the network, which has been described as "Facebook for scientists."

Researchers discover mechanism that helps humans see in bright and low light

| Cells in the retina quickly adjust to darkness by way of an intricate process. |
Ever wonder how your eyes adjust during a blackout? When we go from light to near total darkness, cells in the retina must quickly adjust. Vision scientists at the School of Medicine have identified an intricate process that allows the human eye to quickly adapt to darkness. The same process also allows the eye to function in bright light.

Seeing the light
Researchers find novel pathway that helps eyes quickly adapt to darkness
Feb. 27,
2009 -- Scientists have long known that cells in the retina called photoreceptors are involved in how vision can adapt to darkness, but a study from investigators at Washington University School of Medicine in St. Louis and Boston University School of Medicine has uncovered a new pathway in the retina that allows the cells to adapt following exposure to bright light. The discovery could help scientists better understand human diseases that affect the retina, including age-related macular degeneration, the leading cause of blindness in Americans over the age of 50.

Less invasive glaucoma surgery allows faster return to normal activity
Feb. 6,
2009 -- Surgeons at the Washington University Eye Center are among the first to use a new surgical device to treat glaucoma. Surgery with the device, called a Trabectome, is an outpatient procedure that takes less time to perform and offers a shorter recovery than traditional glaucoma surgery.

Making sense of all the buttons on microwaves, dishwashers and coffee makers is hard enough when you can see them. For people with impaired vision, the gadgets can become more barrier than convenience. A program sponsored by Washington University helps people with poor eyesight maintain their independence by modifying their homes to make them more useful and safe.

Three diseases that cause blindness traced to common root
Cause of vision loss in macular degeneration also plays role in diabetic retinopathy, other retinal diseases
Oct. 10,
2008 -- Scientists at the School of Medicine have determined that the same factors play key roles in three different diseases that can lead to blindness. In age-related macular degeneration, diabetic retinopathy and retinopathy of prematurity, abnormal blood-vessel growth threatens vision. Reporting in the journal PLoS One, Washington University vision scientists say that although the mechanisms are a bit different, all three retinal diseases involve the same immune-system factors.

The way cells die matters to our bodies
How cells die determines whether immune system mounts response
July 17,
2008 -- Every moment we live, cells in our bodies are dying. One type of cell death activates an immune response while another type doesn't. Now researchers at the School of Medicine and St. Jude's Children's Research Hospital in Memphis have figured out how some dying cells signal the immune system. They say the finding eventually could have important implications in the treatment of autoimmune diseases and cancer.

Visual awareness
World Glaucoma Day set for March 6
Feb. 27,
2008 -- Physicians and glaucoma researchers in the Department of Ophthalmology and Visual Sciences at the School of Medicine will join eye-care professionals around the world on March 6, 2008, to observe the first World Glaucoma Day. The global initiative is aimed at raising awareness of glaucoma, a disease of the optic nerve that affects 65 million people worldwide.

Battling blindness
Immune cell age plays role in retinal damage in age-related macular degeneration
Nov. 1,
2007 --
Studying a mouse model of age-related macular degeneration, the leading cause of blindness in older Americans, scientists at the School of Medicine have found age is key in determining whether damaging blood vessels will form beneath the retina and contribute to vision loss. The scientists, led by principal investigator Rajendra Apte, discovered that specific immune cells called macrophages play a role in the disease process in older mice by failing to block the development of abnormal, leaky blood vessels behind the retina.
