New Drugs Being Developed for Macular Degeneration

May 28, 2010

In 2005, two genetic studies of people with age-related macular degeneration (AMD)–the most common cause of blindness in people older than 65–made a surprising discovery. Research showed that defects in a gene that is an important regulator of parts of the immune system significantly increased risk of the disease. Scientists have since identified variants in several related genes that also boost risk, and which collectively account for about 50 to 60 percent of the heritability of the disorder.

Eye colors: Drusen, the yellow flecks in this image of the retina, are common in people with age-related macular degeneration. These flecks are made up of proteins involved in the part of the immune system called the complement system, which has also been implicated in the disease by genetic studies.

At the same time that researchers identified the harmful variation linked to AMD, Gregory Hageman, now at the University of Utah, identified a protective variant found in about 20 percent of the population. “That form is so incredibly protective that people with two copies are almost guaranteed not to develop the disease,” he says. Hageman founded Optherion, a startup based in New Haven, CT, and investigated how to translate the findings into new treatments. Optherion is now producing large quantities of an engineered version of the protein and doing preclinical safety and effectiveness testing–for example, examining whether the treatment can reduce ocular deposits in mice that lack the protein, says Colin Foster, Optherion’s president. He declined to estimate when the company will begin clinical trials of the drug.

Retina Created From Human Embryonic Stem Cells

May 28, 2010

UC Irvine scientists have created an eight-layer, early stage retina from human embryonic stem cells, the first three-dimensional tissue structure to be made from stem cells.

It also marks the first step toward the development of transplant-ready retinas to treat eye disorders such as retinitis pigmentosa and macular degeneration that affect millions.

UV Damage to the Eye

May 27, 2010

Now that Summer is near, we should be careful about the long-term and short-term damage sunlight can do to our eyes.

  • Cataracts
  • Photokeratitis – sunburn of the cornea
  • Damage to the retina, including macular degeneration
  • Cancer of the eyelids

Got Spirit?
Bring it with you to the 5th Annual Triangle VisionWalk! Join the Team Spirit Contest.
This friendly competition will take place before the ribbon cutting ceremony on June 5th. The team with the most spirit will receive an award.

You can show your team spirit with matching team t-shirts, team hats or team banners, just to name a few ideas. The best part is – you are the judge! We will invite one person from each team to join us on stage for the voting process. The winner will be determined by applause.
