Eyes have misgivings about the disease is not so?
Posterior vitreous detachment in order to understand the eye (the eye) need to know about the structure.
It becomes very easy explanation
Vitreous inside the eye is filled with a jellylike substance.
And the cornea of the eye behind the film. Just like to wrap up the vitreous body is present in the cornea.
Vitreous and is usually in close contact with the cornea.
However, as the vitreous and take years to the cornea to have some gaps.
This is the posterior vitreous detachment.
Posterior vitreous detachment flaking off and visus muscarum
Posterior vitreous detachment and a large floating relationship. The two split the symptoms, rather than the overall need to think.
Posterior vitreous detachment
Small gray [tenten] might float dimly on the presence and it gotten it.
When the wall and the blue sky of the luminous color are watched moreover, it is likely to see it in the place where the book is read.
When one of the points is watched, it might be not able to be done.
The point moves only to move eyes together just a little, too.
Even if the point enters view, the true colors is not understood.
Then, how when blinking without moving eyes?
The position of the point changes and the point disappears, and it adheres to the surface of the eyeball, and it is not sick.
It is in the eyeball, and however, if it doesn't change almost and at all, is floating in the corpus vitreum it.
It seems that it grows dim because the macula is in the interior from the crystalline lens.
Moreover, when looking directly because it is gelatinous, the corpus vitreum unsteadily drifts.
It is a visus muscarum if there is such a symptom.
Visus muscarum - cause -
Why does the macula of such the glass inside of the body part appear?
- Hangover when it is embryo
It is considerably fibroid in a developmental phase initial of the embryo in the eyeball.
It is thought that it might remain how much the cell and the fiber, and it floats though those fiber and other cell had changed into the corpus vitreum when having given birth.
Moreover, the embryo has the artery to give the crystalline lens the nutrient.
A small fragment might remain though this artery shrinks to the birth and is absorbed usually.
An adult corpus vitreum is not gelatinous all.
The corpus vitreum is wrapped in the vitreous membrane, and there is a retina like touching the vitreous membrane.
And, the fine fiber has extended from the seam to the entire glass body.
The fine fiber might shrink and break when the age advances.
The splinter of the fiber comes to float easily further so that the corpus vitreum may become more watery from gelatinous, too.
Moreover, the splinter of the cell might remain because the corpus vitreum shrinks little by little and it begins to peel off from the retina.
When the age because of this advances, it comes to see more points drift.
- Blood vessel of retina
The head is hit hard or excessive pressure hangs to the eyeball, and the red blood corpuscle is discharged from a small blood vessel like the string.
Red blood corpuscles might agglomerate to be sticky and unite.
And, the point might be seen when the red blood corpuscle enters the corpus vitreum and it stays by the retina.
It will disappear before long and it disappears because the red blood corpuscle is absorbed to the inside of the body again.
However, because the slight flaw came to see the float by original, such a state is not a visus muscarum to be exact.
Visus muscarum - When it is dangerous -.
Is the visus muscarum a symptom that abnormality is found in the body?There is usually not this.
Even if it is young, even the person that there is no fault on eyes is not gradually anxious though he or she sees the one like the point.
However, it is when the symptom is dangerous.
- Dangerous symptom
Some accidents happen if the number of points increased suddenly compared with before.
When the light glittering done in the eye interior is seen, it is necessary to take care especially.
The retina is related to such a phenomenon.
Floats of a lot of numbers and the light glittering done are usually caused because a part of the retina flaked off.
The retina as are damp softness like the tissue paper and one thickness, and is as delicate as the tissue.
The nerve layer where the light of the retina is felt is fixed in the strata below, and sticks firmly with the corpus vitreum only in the part of the part in the surrounding and the optic nerve.
However, it is only attached loose with the central portion.
Other parts of the retina are kept the positions thanks to the corpus vitreum.
The retina never tears usually and peels off from the nether layer even if hit hard because eyes are very elastic.
However, the retina might be damaged, and a small rip and the hole open in the retina when the high impact joins.
The hole might open because the corpus vitreum adhered to the retina.
The corpus vitreum can strongly pull the retina due to rapid movement and wound, and a small rip be done.
Then, humor vitreus enter the other side of the retina, and the retina comes from the layer below to the surface.
When this occurs, the light glittering done is seen.
The blood vessel ..reticulation.. runs on the surface in the retina moreover.
Therefore, there is a possibility that detached retinas occurs regardless of the amount when bleeding.
Blood flows into the corpus vitreum, the float flickers suddenly, and it comes to see it.
View narrows as will peel off before long the retina, and interrupted with the curtain.
Therefore, it is necessary to go to the hospital at once if coming see suddenly a lot of maculas and the light done especially glittering were seen.
It is because treatment becomes difficult, too, when detached retinas occurs in the large range there is fear of detached retinas.
How many years how are when the macula is seen, too?
It is likely do not to have to worry so much if there is no symptom that feels the light glittering done.
The brain comes not to consider light before it lives though light doesn't disappear if it doesn't worry.
However, the person who sees the float will still undergo the inspection of the ophthalmology department.
Posterior vitreous detachment- progress -
It can be said that the PVD off is a normal symptom that happens to some the people.
However, when flaking off, the corpus vitreum might pull the retina when there is adhesion on the corpus vitreum and the retina.
And, when the adhesion is strong, the retina is occasionally strongly pulled.
As a result, detached retinas might be caused.
Posterior vitreous detachment- symptom -
As a result, when the retina is pulled, light might be seen though the corpus vitreum and the retina adhere.
The one like the shining circle is seen though it is thought that how to see it is different depending on the person.
Posterior vitreous detachment- action method -
It can be said that the PVD off is a symptom that occurs with aging.
Therefore, there is a book assumed that the PVD off is one of the symptoms of senility and not sick, too.
However, it can be said that it is an urgent situation if other symptoms (detached retinas etc.) caused with the PVD off exist.
You will consult the specialist at once if abnormality is felt in eyes even a little.
