<DIV><FONT face=Arial size=2>this research has been giving my significant other

<DIV><FONT face=Arial size=2>My father was aware and interested in research
years ago, some of witch promised to stabilize one's sight.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>We were content in knowing that this type of thing
is so experimental as to offer no real hope for full usable sight. Those of us
for whom this research can have some glimmer of hope probably will not see the
day when we can read and drive using our own eyes, so I prefer learning to live
as full a life as possible as the blind person that I am.</FONT></DIV>

<P>Scientists believe the brain of a blind woman rewired itself and enabled
her to see after partial vision was restored to sections of her retina through
gene therapy.</P>
<P>The finding surprised scientists at the University of Florida College of
Medicine and the University of Pennsylvania who two years ago began testing
the safety of gene therapy in three patients born with Leber congenital
amaurosis type 2, a rare blindness condition. The findings are contained in a
study to be published Thursday in the New England Journal of Medicine.</P>
<P>“This was phase 1 of a National Eye Institute study and we wanted to
measure whether gene therapy was safe for the eye and safe for the body,” said
Dr. Artur Cideciyan, a research associate professor at the University of
Pennsylvania. “We were hopeful that something positive would end up occurring
as well.”</P>
<P>Scientists found that within weeks of adding healthy genes to the retinas
of study participants (a woman and two men between the ages of 21 and 24), the
three began to experience significant improvements, including improved
sensitivity to light.</P>
<P>“We found that the improvements occurred only in the treated eyes and in
the regions that were injected with the new genes,” Cideciyan said. “We also
found that the improvements and the safety were maintained for 12 months after
the initial injection.”</P>
<P>The tiny portions of the patients’ retinas that received gene therapy
experienced restored function up to 1,000-fold during the day and 63,000-fold
at night.</P>
<P>But it was the woman in particular who surprised researchers when she
announced that a year after receiving treatment, her vision continued to make
small improvements. She said she could read the digital clock in her parents’
car – something she had never done before.</P>
<P>“That prompted us to measure where her gaze was fixed while looking at a
variety of dim targets,” said Dr. William W. Hauswirth, a professor in the
ophthalmology department at the UF College of Medicine, who led the study.
“This showed she now has two preferred centers of vision rather than one,
depending on the brightness of the object.”</P>
<P>Cideciyan said healthy adults have a single preferred center of vision that
they use to see objects. Based on their findings, researchers hypothesize that
the female patient’s brain rewired itself to use two preferred centers, which
it shifts back and forth between depending on the situation.</P>
<P>“I think that it is a very intriguing hypothesis … that she learned to use
an area of her retina that was improved through gene therapy,” said Dr. Brian
Brooks, an investigator with the National Institute of Health’s National Eye
Institute.</P>
<P>“We don’t yet understand the precise mechanism that occurred to make this
happen,” said Brooks, who did not participate in the NEI-supported study. “But
the hope is that we will be able to use the finding to cold train patients to
use new areas of their retinas that they’re not accustomed to using.”</P>
<P>The finding could also prove beneficial to others with degenerative retinal
conditions similar to Leber congenital amaurosis, which is a leading cause of
blindness in infants and children, Cideciyan and Brooks said.</P>
<P>Cideciyan said the safety trial will continue for the next three years and
the participants will be followed for 15 years, as mandated by the U.S. Food
and Drug Administration. The study also will be expanded to include other age
groups and participants.</P><BR style="CLEAR: both">
