Retinal detachment- there is no such symptom or nor -
Might you likely to feel light suddenly, and wave by curtained dopy one?
When it seems that the outline of the seen thing becomes unclear, an innumerable point might be seen.
The ophthalmologist will look after all of such a symptom with sick symptoms of important eyes if any of such a symptom is unending though it is not possible to say.
In some cases, flaking off of the retina might be a cause.
- of ..Retinal detachment.. - structure ..knowing...
The eyeball is globular as its name suggests excluding in front of that swells.
And, the condensing organs of eyes have been installed on this swelling part.
In addition, the film of the entire eyeball is lightproof excluding this swelling part.
The part is called a cornea by becoming like the window beautifully transparent usually rotundly.
[Ushironi] of the cornea has the iris, and has the part that opened roundly that is called a pupil at the center.
The iris automatically expands, narrows the size of the pupil, and adjusts the amount of the light that enters eyes.
[Suguushironi] of the iris has the crystalline lens.
This crystalline lens synchronizes with the cornea, and concentrates light on the back of the eyeball.
Here, light is changed by the stimulation by electricity, and this is transmitted to the brain.
Therefore, it can be said that it is not eyes but the brains that actually do "See" function.
[Ushironiha], gelatin of crystalline lens, and transparent object and corpus vitreums are blocked.
The majority are water in the corpus vitreum, and alone cervine is not very included as for the solid.
Retinal detachment - Especially, it knows the retina -.
The films of the eyeball are three layers.
- 1Layer on extra side
The most outside layer covers most of the eyeball with the strong film that is called a sclerotic coat, and prevents light from going into it.
However, this sclerotic coat becomes corneal that passes light in front of the eyeball.
- Layer in the middle
The film in the middle is very complex.
The film in the middle is essentially a film of the spell with which 4/5 of the eyeballs is covered though it divides into some organizations at the front of the eyeball.
- 1Layer in turn
The most inside layer and this are retinas.
The retina gives shape, the color, and feeling of quality to be able to perceive the brain to the image of light that catches one's eye by a film as thin as paper.
It consists of a lot of different following layers though the retina is a thin structure like paper.
1. Neuronal cell located on side one of these days at center of the eye
2. Photoreceptor cell in the middle part of retina
3. Having coloring matter cell that queues up outside near choroid
The number of photoreceptor cells in the retina is the numbers of some one million one.
It is said that there are about 130 million numbers of photoreceptor cells on one eye.
Retinal detachment - When the retina causes abnormality -.
The retina should be normal to keep eyesight.
However, the retina might be ruined.
It is from a choroid to flaking off of the retina that replenishes nourishment with the retina in [suguushiro] of the retina.
Then, the retina changes in quality, and might lose one's eyesight.
It is a symptom called it is Retinal detachment.
A lot of Retinal detachment is seen between 50-year-old or more people, and abnormality is admitted in both eyes as for the one-quarter of the patients.
As for the person who is getting a diabetic, it is known that the normal person hangs easily by as much as 20 times to Retinal detachment.
Retinal detachment - How does the retina flake off -.
What does the retina flake off?
It is not when connecting with the retina though the blood vessel in the choroid supplies nourishment to the retina.
Only very small amount sticking material that ties to the choroid the retina is between both films.
On normal eyes, the retina has stuck to the choroid by the pressure of the corpus vitreum.
However, the retina will flake off from the nourishment replenishment source when blood and other materials enter between the retina and the choroid.
In many cases, Retinal detachment starts from a small hole and the rip, etc. caused in the retina.
The liquid soaks there, and the retina comes from the choroid to the surface.
- Why is it at that hangs easily to Retinal detachment in an elderly person?
The corpus vitreum begins to shrink, and starts leaving the surface of the retina when 40 years old is passed.
Damage will be caused in the retina before long the result of the pull always and.
The retina is made for water to leak from this damage part to the outer retina and to come to the surface, and it causes flaking off.
- Why is it at that the diabetic hangs easily to Retinal detachment?
The reason for the diabetic is that the hemorrhage in the retina might be caused.
The retina might flake off when blood and other liquids flow in the back of the retina.
Retinal detachment - Defend the retina, and for prevention -.
What can you do for the prevention of Retinal detachment?
- Strong sunlight is noted.
It is necessary to avoid being exposed for a long time in strong sunlight.
- The nourishment of eyes is removed.
Moreover, it is very important for keeping eyesight to take the nutrient properly.
It is important that a proper amount take the vitamin, the mineral, and the amino acid.
A large amount of vitamin A is contained in the retina.
The coloring matter that does working that accustoms eyes to dim light is made of the material and the protein with chemical formulae that look like vitamin A.
The vitamin B family doesn't allow them to lack it in the health of eyes as well as vitamin C and D either.
The meal that was able to be the balance contains these necessary nutrients.
- Regular medical examination
As for the eye deficiency, it might be good once every at least two years for 40-year-old or more person to visit the ophthalmologist because it is a lot of.
As a result, Retinal detachment can be prevented beforehand.
In the hospital, the eyeground can be examined directly.
A rip and a small hole of the retina that precedes the flaking off part and flaking off of the retina can be discovered by inspecting the interior of the eyeball.
And, if treatment is given at the early stage, a serious sickness will be prevented.
The earlier the discovery is, the more the great result it is likely to become.
