Giving A Chance To See The Gum Trees, And Lots of Plum Trees
Australian TV personality Don Burke of Burke's Backyard is almost as well-known here for his woolly jumpers as he is for his enthusiasm in the garden. After 17 and a half years, the final episode of Burke's Backyard aired on Friday night.
Don has donated the jumper he wore on the very first episode of the show for auction by Retina Australia. With three days left, the jumper has attracted bids as high as $6 100 at online auction site eBay.
Retina Australia offers support to people affected by retinal degeneration and raises funds for Australasian research that will contribute to finding a cure or treatment for retinal degenerative diseases. A donation such as this will help Retina Australia to continue this work, offering hope to individuals and families facing the effects of vision loss.
For more information, visit the Burke's Backyard Web site. A link to the eBay auction is given in the righthand column on the front page.

Right On The Tip Of My Tongue
The New York Times reports progress by University of Wisconsin researchers working on the BrainPort, a device that allows visual input to be felt by the tongue rather than seen through the eyes:

Blind people who have used the device do not report lasting effects. But they are amazed by what they can see. Mr. Weihenmayer said the device at first felt like candy pop rocks on his tongue. But that sensation quickly gave way to perceptions of size, movement and recognition.

Stem Cells Successfully Transplanted in Mice With RD
In a study conducted at the Schepens Eye Research Institute in the US, retinal stem cells taken from healthy mice were transplanted into the retinas of mice with retinal degeneration. The stem cells developed into retinal cells. Another positive outcome of the transplantation was that already dying cone cells appeared to "regain or retain their function."
The research appears in the November 2004 issue of Investigative Ophthalmology and Visual Science. The abstract is freely available online (Multipotent Retinal Progenitors Express Developmental Markers, Differentiate into Retinal Neurons, and Preserve Light-Mediated Behavior,' Klassen, H. and others, Volume 45, pp 4167-4173).

To test whether the mice with transplanted stem cells could see better, the team then placed them and the control mice (without the transplants or with non-stem cell transplants) in dark cages and flashed a series of increasingly lower level lights at both groups over a period of time. Mice are photophobic and stop their normal activity when they detect light. The researchers took advantage of this natural response and found that the mice with the transplanted tissue continued to respond to the light as it reached the lowest levels. The control mice did not.

Ray Howard is a 73-year-old retiree who plays classical music at a hospice in Colorado, USA, twice a week:
Ray had given up the guitar for 15 years, too busy earning a living. In 1993, he took up the instrument again. "I picked it up during the O.J. trial because I was so frustrated with the way it was going," Ray said. "I couldn't watch it anymore."
So he found his "dream guitar," a Kohno, and began learning classical guitar through talking books and tapes. Now he listens to classical guitar CDs and knows about 50 songs by heart.

Harold Riley, who has Usher Syndrome, continues woodworking, making model trains and cars:
"I don't think of myself as more special than anyone else who is deaf and blind," Riley explained through the help of his wife and interpreter, Donna. "This is who I am, and making toys is what I do."
Riley, 62, acknowledged that he has never heard the excited hum of one of his four table saws as he gets ready to create yet another of his more than 25 wooden designs.

Canadian Gene Therapy May Inhibit Photoreceptor Death
Robert Korneluk Ph.D, director of the Solange Gauthier Karsh Laboratory in Ottawa, recently announced that a gene therapy currently being investigated may be available in three years time:
The announcement was made during a presentation at The Foundation Fighting Blindness - Canada's Vision Quest 2004 conference, held on 6 November in Ottawa.

The disease [RP] is caused when genetic defects lead the cells in the retina to die prematurely. Mr. Korneluk and his coworkers, who are conducting research on XIAP, the X-linked inhibitor of apoptosis (cell death), believe that XIAP therapy can make the retina's photoreceptor cells more resistant to dying, and therefore preserve sight.

Butterflies and RP Inspire Colourful Home
Californian J Jackson created a colourful home inside and out when wife Sonja lost the sight in her right eye through retinitis pigmentosa. Eight years after J began, their home has a butterfly motif that draws curious visitors off the street ('Vision of love family & self,' The Salinas Californian, 16 October 2004).

Advances in Adult Stem Cell and Retinal Transplant Research
Canadian researchers from the University of Toronto have shown that stem cells taken from the human eye will regenerate:
The research was published online 25 October 2004 in the Proceedings of the National Academy of Sciences before print (Coles, B. et al, 'Facile isolation and the characterization of human retinal stem cells,' PNAS, November 2 2004, Vol. 101, No. 44, pp 15772-15777).
Meanwhile, in Louisville, Kentucky, USA scientists have successfully transplanted retinal tissue, taken from foetuses, into the eyes of patients with retinal degeneration:
The article discusses both the treatment and the need to develop guidelines on the use of foetal cells in treating disease.
Note: This entry was updated on 12 November 2004 when I realised that I had incorrectly referred to the transplanted foetal retinal tissues as 'stem cells.' My apologies for causing any confusion. Thanks to discussion of the research on RPList I became aware of my mistake.

To test the potential of the stem cells in a living organism, the researchers transplanted them into the eyes of mouse pups. Four weeks after transplantation, most of the human stem cells had appropriately migrated, differentiated and integrated at the right developmental times.

Three years ago Elisabeth Bryant believed she would be blind for the rest of her life. "I couldn't see anything," she says. Now, although her vision is not perfect, she can see well enough to read, play computer games and check emails. Bryant has retinitis pigmentosa, an eye disease that has blinded four generations of her family. What has saved the sight in one of her eyes is a transplant of a sheet of retinal cells. The vision in this eye has improved from 20:800 to 20:84 in the two-and-a-half years since the transplant- a remarkable transformation. So far, six patients with either advanced retinitis pigmentosa or macular degeneration have had similar transplants.

"I'm no architectural expert," she cautioned me as we began our tour of the
building's exterior. I assured her that it didn't matter. On the Web, with
the help of my screen reader program, I'd pored over articles describing the
hall's idiosyncratic asymmetries, its billowing curves, I imagined, making
it look something like an extraterrestrial Spanish galleon about to sail over
Bunker Hill. All I needed was for her to help me make sense of the place.

Settling In Again
After a few weeks away I'll soon be able to write about the Retina Australia Congress, recently held in South Australia, and my visit to give a blood sample to the Inherited Retinal Disease Register. My #ozrplist friends and I enjoyed our few days together in Adelaide, taking in the beach at Glenelg, the International Rose Garden, the O-bahn guided bus route, the German-founded township of Hahndorf and quite a few pubs along the way. I'm also posting from a new computer at home, which should speed up my blogging. I'll be catching up on news and information relevant to people with RD very soon.
