Eye Floaters Causes and Cure – What Causes Eye Floaters?
There are two main types of eye floaters, and the two have very different causes. Eye floaters are classified as either benign or pathological, with the former being the most prevalent type.
There is no way of telling whether you have benign or
pathological eye floaters, and therefore, you should visit a qualified health
professional as soon as you develop the eye floaters and again whenever you
notice a drastic change in the number or severity of the floaters.
To
understand the causes of eye floaters, first you need to understand the basic
eye anatomy. The eye is filled up with transparent jelly-like liquid, called
the vitreous humor. This liquid is about 99% water and 1% protein. The vitreous
humor is attached to the eye at the optic nerve head (found in the posterior
part of the eye) and at the anterior part of the eye orbit.
However,
separation of these attachment points is fairly common, and may occur as a
result of injury to the eye, strenuous exercise, or for no particular reason.
The detachment of the vitreous humor from posterior part is the most common
cause of benign eye floaters.
When
this gel-like solution is detached, it will now be free to move around and
sometimes it will make contact with the retina. When this happens, the person
will see flashes, called photopsias.
When
the vitreous humor is free to move, it progressively becomes less transparent
because the proteins tend to aggregate together. These aggregates give rise to
floaters, technically called vitreous syneresis. It is estimated that over half
of the world's population will develop eye floaters at some point in their
lives and they can occur at any age, although they are more common in older
adults.
The
other type of eye floaters is the pathological one. In this case, there is a
similar detachment of the vitreous humor, however, it occurs from the anterior
attachment. When this happens, the retinal tissues may get pulled to such an
extent so as to create a hole in the retina.
As
a result, some blood can leak into the eye cavity, and this gives rise to eye
floaters. This type of eye floaters can be very dangerous, because if it is
left unattended, total retinal detachment can occur. This will require surgery
to be corrected, and it can lead to blindness if it is not treated.
There
are other conditions and circumstances that can cause blood to leak into the
eye cavity, the most common of which is proliferative diabetic retinopathy, a
fairly common condition in diabetics who do not manage their condition
properly. What happens in this case is that abnormal blood vessels will grow in
the retina, and these may bleed into the vitreous humor.
Other
conditions that can give rise to eye floaters include macular degeneration,
foreign bodies that end up in the eye, and some parasites.
Eye Floaters Causes and Cure – Etiology of Eye Floaters
In most cases, the etiology of eye floaters involves an
accumulation of proteins and/or debris in the vitreous humor of the eye - that
jelly-like solution that fills the ocular cavity. Eye floaters are found behind
the lens and in front of the retina.
Persons with eye floaters describe them as dots, squiggly
lines, or cobwebs in their fields of vision. The number of floaters can vary
from one to hundreds, and they become more pronounced in bright light
conditions.
Eye
floaters are more common in older adults. This is because with age, the
vitreous humor starts losing its shape, and the proteins that are normally
dispersed in the solution may aggregate and become visible. What you see is
actually the shadow of these strands of protein.
Perhaps
the most common etiology of eye floaters is posterior vitreous detachment. This
describes a condition characterized by the 'peeling away' of the vitreous humor
from the retina. They may occur gradually or suddenly. People who are near-sighted
are more at risk of posterior vitreous detachment, as are people who have
undergone cataract surgery.
When
posterior vitreous detachment occurs, the person will typically experience eye
floaters, or if floaters are present already, their number will quickly
increase. Flashes of light may also be seen. Untreated, posterior vitreous
detachment can cause retinal detachment or retinal tears.
Retinal
tears can also occur independently of posterior vitreous detachment and this
will also cause eye floaters to appear. About half of people over 50 will have
some degree of vitreous detachment from the retina, and this can lead to a
retinal tear.
As
the retina is pulled, small blood vessels in the retina may burst and blood may
leak into the vitreous humor. This will cause the person to see black dots or
smoke in the field of vision. Flashes of light can also be experienced.
However, note that flashes of light do not necessarily indicate a retinal tear;
other causes, such as migraines, can give rise to this phenomenon.
Another
possible etiology of eye floaters is retinal detachment. This occurs when
retinal tears are not treated immediately, and result in the retina separating
from the wall of the eye. This will have serious repercussions on your vision,
and may lead to blindness. Retinal detachments will also cause eye floaters to
be experience, although this is one of the rare causes of floaters.
Other
possible etiologies of eye floaters include eye infections, inflammations, eye
injury and eye diseases. They can also arise as a complication of
diabetes.

This post is from the
Eye Floaters No More Program. It is created by Daniel Brown, a former sufferer and professional health
researcher. As a professional health researcher, Daniel Brown was able to
use his background to find a permanent cure for himself when he suffered from
eye floaters. His in-depth knowledge about eye floaters enabled him to create a credible,
natural and effective step-by-step alternative treatment plan to help other
sufferers get healed, without the use of synthetic drugs or risky surgery.
The Eye Floaters No
More Program can be best described as a step-by-step guide with detailed
instructions for naturally and permanently curing eye floaters and other vision
problems. Simply put, eye floaters are sediments found inside the vitreous
humor, a gel-like substance that fills the hollow space at the back of the lens
and helps maintain the shape of the eyes. These sediments appear because of the
changes that happen with the vitreous humor after infection, inflammation, or
severe damage to the eye. According to Daniel Brown, the Eye Floaters No
More program was designed to help you treat the root cause of this problem
without depending on prescription drugs, surgery and other mainstream medical
treatments. Aside from eliminating all signs of eye
floaters, like dots, shapes and blurs, this program is also filled with lots of
techniques and tips for treating a host of eyesight symptoms and problems.
