Hi Vincent, 

Are you visually impaired in any way?

My advisor has assigned a Post doc and a couple of more people in the
sonnification lab at Georgia Tech to start working with me on an Accessible
Statistics project.  What we need to determine is exactly how to go about
approaching the entire problem.  The ultimate goal is to create both an
formal and informal approach towards the topic, such as just presenting and
teaching Statistics to blind high school and college students.  The other is
a way to make the output from SPSS and other calculating packages
accessible.  

Since SPSS is by far the leader in the industry, we would like to make their
program accessible to screenreading programs.  We know that "R" can be
utilized by using command lines from the terminal prompt, but that still
requires blind students to do way more than their sighted peers just to do
their calculations.  What we really would like input from the community
about is what is the most important thing to attack first.  I have a STATS
class this semester and we are using SPSS for the lab portion and also to
complete any class project.  This is now the standard in most universities
in the country, whether it is undergratuate or graduate level.  Since I will
have another year and a half of classess in Statistics and then research on
a dissertation, making SPSS is the priority for me.

I recently got the following article from a friend and thought it was quite 
exciting if it can be perfected.  I am sending it along for those interested

in corneal transplants.
Enjoy!

Subject: Canadian scientists envision synthetic corneas

Canadian researchers may have made a breakthrough in the treatment of 
blindness caused by damaged corneas.

They've developed a biosynthetic cornea that can actually help the eye 
repair its own damaged eye tissue and restore vision. And with further 
research, they say their approach could help restore sight to millions of 
people around the world who have lost their sight from diseases that lead to

clouding of the cornea.

The research, published today in the journal Science Translational Medicine 
is a small one, involving just 10 people. But scientists say they were 
surprised that the treatment worked in the majority of patients who had 
scarred corneas, helping to restore the sight of nine of the 10 patients.

The cornea is the thin, transparent layer of collagen and cells that acts as

a window on the eyeball. In most cases of corneal damage, only a transplant 
can restore sight.

But in this research, Dr. May Griffith of the Ottawa Hospital Research 
Institute, the University of Ottawa and Link?ping University in Sweden 
created corneas using biosynthetic collagen produced in the lab that was 
moulded into the shape of a cornea, much like a contact lens.

After first testing the corneas on pigs (who have eyes similar to humans), 
they recruited 10 Swedish patients with advanced keratoconus, or central 
corneal scarring. Each patient underwent surgery in 2007 to remove damaged 
corneal tissue. That was then replaced with corneas made from synthetic 
human collagen, which were sewn onto the eyes.

For two years, researchers watched what happened. Over time, the implants 
acted as scaffolding to help the eye restore normal corneal cell and nerve 
growth.

"You put the material in the eye and it becomes almost an integral part. It 
allows the natural cells of the person treated to go into the material and 
become part of it," co-author Rejean Munger of the Ottawa Hospital Research 
Institute told CTV News.

The corneas even became sensitive to touch and started making tears to keep 
the eyes oxygenated.

Griffith says while the study was intended only to test the safety of the 
new corneas, her team found that nine of the 10 patients saw their vision 
improve, though some needed to wear contact lenses. The 10th patient is 
improving though much more slowly.

"We were actually very surprised and happy that we saw improvement in the 
vision," Griffith said.

"After surgery, patients didn't have perfect vision, but they could see 
better," she says. "One patient had almost perfect vision; others had 
slightly less than perfect vision."

The research was published Wednesday in the journal Science Translational 
Medicine.

Dr. Keith Gordon of the CNIB notes that there are millions of people in 
Canada and around the world who need new corneas, but there is a dire 
shortage of donor corneas. A synthetic cornea from a lab would be an 
important new way of treating patients.

"If these transplants are as effective as they appear to be, we have got a 
winner. And it will be exciting and useful for people with vision loss due 
to corneal disease," he says.

Researchers think it will take another five years to further improve the 
implants, and to test them in other eye conditions.
