Natural Eye Care - Treatment And Prevention Of CataractsCataract
is a
disease which involves clouding of the
crystalline lens of the
eyes.
The lens
is an important structure as it is responsible
for focusing light onto
the
photoreceptors in the retina. Cataract
varies
in severity from mild to
complete
opacity of the lens,
thereby obstructing the passage of light. This
condition
is relatively common in older people. In fact by
the age of 80, it is
estimated
that more than half of the population of the
United States will either
have a cataract
or have had cataract
surgery.
EmailIn majority of cases, cataracts progress slowly and as they grow in size they cause vision loss and are potentially blinding once left untreated. Both eyes are usually affected but one eye is almost always affected earlier than the other. Cataracts are generally classified as one of three types. A subcapsular cataract typically starts at the back of the lens. People who are at risk for developing this type include those with diabetes, severe hyperopia (farsightedness), retinitis pigmentosa or those who are taking high doses of steroids. Another type is called nuclear cataract which develops in the center of the lens as people age. The third type is called cortical cataract, which forms in the periphery of the lens and slowly extends to the center. This type is commonly seen in patients with diabetes. Cataract
Symptoms
A cataract starts
out
small and has little effect on vision
but as
the lens
become more opaque, vision is
blurred a little. Ultimately,
clear vision
is compromised and there is a significant loss
of visual acuity.
There
is also a concurrent loss of contrast
sensitivity wherein contours,
shadows and
color vision
become less vivid. A cataract can
also make light appear
too
bright or glaring due to its scattering inside
the affected eye.
Patients who
drive at night will also notice that oncoming
headlights cause more
glare than
before. In high risks groups such as diabetics,
a 'halo' may be
observed around
lights at night and this condition is normally
confined to one eye. The
red
reflex will be absent and colors may not appear
as bright as they once
did. As
a rule, the
type of cataract
present dictates which symptoms will be
experienced and how early they
will
manifest. During the early stages of a nuclear cataract,
there
may be a
temporary improvement in near vision,
called
"second sight." However,
this is short-lived and will disappear as the cataract
develops. As for
subcapsular cataract,
it may not cause any symptoms until its advanced
stages.
Other notable symptoms of this eye disease
include double vision, poor
night vision,
frequent increases in eyeglass or contact lens
prescriptions
and white
or "milky" spot over the pupil of the eye.Cataract
Treatment
When symptoms start to appear,
patients can temporarily
improve vision
by using new glasses, strong bifocals,
magnification or other
visual
aids and eye care products. Once cataracts
have
progressed enough to
seriously
impair vision, surgery is the best treatment
option. Cataract surgery
is a
simple and relatively painless procedure yet it
is very effective in
restoring
vision. In fact, it is the most frequently
performed surgery in the
U.S., with
over three million Americans undergoing cataract
surgery
annually.The surgery is commonly performed by making an incision into the capsule of the cloudy lens in order to remove it. Two types of cataract surgery can be done to remove the defective lens: extracapsular cataract extraction, or ECCE and intracapsular cataract extraction, or ICCE. In either case, the lens is removed and replaced with a clear plastic intraocular lens implant. The surgery is usually performed as an out-patient procedure using a local anaesthetic. As with any other surgical techniques, complications are possible following cataract surgery. The most common complications include endophthalmitis, retinal detachment and posterior capsular opacification. Mangosteen
Help
for Cataracts
Among the five essential
senses, vision is
arguably the most
important. The human body has been specifically
designed to receive
information
from its immediate environment from visual
stimuli.
As people age, the
eyes
become susceptible to degenerative changes that
accompany the natural
aging
process. Cataracts
are the prime example of such changes and they
can
be caused
by a combination of a variety of factors. These
include lifestyle
(smoking and
excessive alcohol intake), excessive exposure to
UV rays, other
diseases that
affect vision
(diabetes
and gastrointestinal disorders), vitamin
deficiencies,
fatty acid intolerance and side-effects of
medications.Some experts also claim that the most crucial factor that leads to the development of cataracts as people age is poor nutrition. This is particularly true considering the fact that cataract usually take its toll during the latter years of life when people become susceptible to malnutrition due the decline in the bodies capability to absorb all the essential nutrients from the diet. This is where mangosteen can prove to be extremely beneficial as it contains essential vitamins and minerals such as Calcium, Iron, Phosphorous, Polysaccharides, Potassium, Stilbenes, Vitamin B1, Vitamin B2, Vitamin B6, and Vitamin C. In addition, mangosteen is loaded with powerful anti-oxidants called xanthones which can prevent damage to the lens caused by harmful free radicals. There are 200 types of xanthones known to man and mangosteen has 40 of those. This makes mangosteen truly unique and there is simply no food source in the planet that can rival its quantity of beneficial phytonutrients. This means that early and continuous intake of mangosteen supplements can effectively address the nutritional deficiency commonly seen in old age, thereby preventing the onset and development of cataracts.
