Scientists Discover Gene That Causes Vision Loss; Foods That Are Good For Your Sight
If you want to know the cause for your vision loss then you need to read this article.
Losing your vision as you age and become old is something natural. But there are a section of people who lose their vision right in their middle age and this is something very unusual. Also this is something which is believed to be on the rise in the past few years.
The most worrying part is, majority of the people still do not know what exactly is the cause for this condition. Well, if you are one among the victims or you have one in the family suffering from this problem then you need to check this out.
Recently a team of scientists have discovered the cause for this problem. It is a gene that may damage eye cells by gradual degeneration of retina, and lead to sight-loss among the middle age people.
According to the scientists it is the chemical changes in the eye that can lead to blindness in middle-age.
Details
Of
The
Study:
During
the
study
the
team
of
researchers
examined
how
changes
in
a
gene
-
known
as
RPGR
-
can
damage
eye
cells
to
cause
a
disorder
known
as
X-linked
retinitis
pigmentosa
-
a
chronic
hereditary
eye
disease
characterized
by
black
pigmentation
and
gradual
degeneration
of
the
retina.
The sad part is that the condition is incurable and affects night and peripheral vision before gradually causing blindness in middle age.
For the study the team from the University of Edinburgh took skin samples from two patients and transformed stem cells - which can change into any cell type - into light-sensing eye cells known as photoreceptors. They compared these with cells from healthy relatives of the patients.
Photoreceptors - which decay in retinitis pigmentosa patients - differed in their fundamental structure when compared with those from family members.
Meanwhile, follow-up studies in mice identified key molecules that interact with RPGR to maintain the structure of photoreceptors.
When RPGR is flawed, the structure is compromised and photoreceptors cannot function correctly, leading to sight loss.
Dr Roly Megaw, who is the lead researcher of the study says that with a better understanding of the RPGR gene and its effects on photoreceptor cells, they hope to come out with treatment measures as well in the near future.
The research was presented on September 5 at the Eye Development and Degeneration 2017 conference in Edinburgh, and is published in the journal of Nature Communications.
Few Foods That Are Good For Your Eyesight:

salads.
Spinach:
All
green
leafy
vegetables
are
good
for
the
eyes.

contains
lutein
and
zeaxanthin
that
prevents
cell
damage.
Also
lutein

the
eye
muscles
stronger
and

kind
of
eye
infections
at
bay.
Nuts:

and
cashew
are
rich
in
vitamin
E.

these
nuts
on
a
daily

muscle
degeneration
and
vision
loss.
