DE102004043965A1 - Spectacles treating amblyopia at early age in childhood and improving visual acuity in glaucoma, employs spectacle shades made from partially transparent, thin colored material - Google Patents

Abstract

The stenopeic shade or screen, with perforations having various sizes and separations, is made from a thin (0.15-0.3 mm thick), colored material which is 2.0-50% transparent. The holes are of two different sizes and are arranged in upper or lower areas in accordance with the nature of the visual defect, such as short sightedness, or far sightedness. The shade is made of white material.

Description

The invention is a stenotic gap filter goggles and relates to a device suitable for the treatment of amblyopia, especially in early childhood, and the improvement of visual acuity, especially in glaucoma and other eye diseases.
Class A61F 9/00

amblyopia is like "one innate or acquired weak-sightedness, in the true sense, the without organic eye findings due to real functional failures of the Eye due to longer Disuse of the eye, v.a. of the squinting eye ... "known (see for example: Lexicon of Medicine, edited by the editorial staff of the publishing house Urban and Schwarzenberg, 3rd, revised edition).

According to conventional medicine, it is known that amblyopia can not be treated at a ripe age (see, for example: Jack J. Kanski, Manfred Spitznas: textbook of clinical ophthalmology, Georg Thieme Verlag Stuttgart - New York, 1987, p : "When you have to give up the occlusion because of lack of success, you have to decide on an individual basis." In general, after the age of 10, improvement of the vision is no longer to be expected "and
Franz Grehn: Ophthalmology, - 28th, completely revised and updated edition - Berlin; Heidelberg; New York; Hong Kong; London; Milan; Paris; Tokio: Springer, 2003 p. 419, where it says: "Consequences of strabismus: the most dangerous consequence of strabismus is amblyopia (weak-sightedness of an eye). It results from the suppression of visual information of the eye. An amblyopia can only be treated in the first years of life, as long as the visual system is still "plastic." Later, the weak-sightedness is irreversible and persists throughout its life ").

These statements are widely used in conventional medicine, because the doctors do not For some reason, the development of amblyopia in many cases also in the early Childhood can not be eliminated if the occlusion of the better-looking eye and the use of corrective lenses used for the amblyopic eye become.

you have to say that the occlusion method has big drawbacks, which the medical profession do not recognize: on the one hand disturbs her visual acuity of the better-looking eye, on the other hand, in the occlusion of the better-looking Eye becomes the size of the pupil the worse-looking eye significantly enlarged and thereby it still sees worse and needs a stronger one Correction glass. But the stronger that The correcting glass is, the smaller the area of sharp vision becomes of the amblyopic eye, making it harder to reach this eye treat because the change the distance from the eye to the image even after a few centimeters Deterioration of visual acuity leads. For children it is practically impossible these claims to preserve and a strictly limited area between the eyes and to keep the picture. This is another reason why the vision may be affected by amblyopia in childhood in many cases not be improved by the occlusion method, especially if the refractive ability of the Eye is limited.

in the Over time, the visual acuity continues to decrease because of the better-looking Eye the curvature to adjust the eye lens of the amblyopic eye according to its need starts and this is the worsening of the ill-fated Eye on. The eye is severely visually impaired.

It is a device for treating amblyopia and improving the condition visual acuity at any age of the person known, the one in front of the eye stenopaic gap aperture (Hole aperture) which contains made of an opaque fabric and with different Hole and hole spacing sizes and provided with a light shield arranged between the pupils which is the visual field of the better-looking eye at about 2/3 of the Nose side covered (DE 10 2004 027 464.9 from 04.06.2004).

Because in this device, the hole aperture made of an opaque material, it can be the small one Children scare.

Also in glaucoma and other eye diseases can be such visual device especially at high intraocular pressure overload the eye additionally.

task

Of the Invention is based on the object, a visual device at the beginning to create the type mentioned, with which the treatment of amblyopia in early childhood and improving visual acuity especially to reach in glaucoma sufferers.

• – das Kind bekommt die Möglichkeit mit dem amblyopen Auge scharf zu sehen, wenn es durch die Löcher schaut, die fast das ganze Sehfeld der Löcherblende besetzen, weil der Abstand zwischen den Grenzen am nächsten benachbarten Löchern der augenblicklichen Größe der Pupille gleich ist. Gleichzeitig wird das Auge nicht überlastet, weil es sogar durch die Teile der Löcherblende, die zwischen den Löchern sich befinden, die Zeichen des Bildes und die Gegenstände auch erkennen kann. Durch das scharfe Sehen wird die Sehkraft des amblyopen Auges verbessert und die Amblyopie wird nach dem Training behandelt. Außerdem vor solchen Lückenfilterbrille bekommen sogar kleine Kinder keine Angst;
• – weil die Lückenfilterblende aus einem dünnen Material vorgesehen ist (etwa 0,15-0,3mm), kann das Auge durch verschiedene Löcher der Lückenfilterblende, auch durch die Seitenlöcher, gut sehen, weil alle Lichteintrittsöffnungen für das Auge in diesem Fall ohne Verringerungen bleiben;
• – da die Lückenfilterblende aus einem nicht voll durchsichtigen (etwa 20-50 Prozent) farbigen Material vorgesehen ist, gibt es die Möglichkeit den Betroffenen, besonders den Glaukombetoffenen solche Farbe mit solcher Lichtdurchlässigkeit des Materials zu benutzen, die am besten der Lichtempfindlichkeit der Augen entsprechen und gleichzeitig das scharfe Sehen ermöglichen.

This problem is solved with the features listed in the protection claim 1, wherein the gap filter panel of a not fully transparent (about 20-50 percent), colored, thin, (about 0.15-0.3mm) material is provided. This achieves the following:

• - The child gets the opportunity to see with the amblyopic eye sharp when looking through the holes that cover almost the entire field of vision of the lion because the distance between the boundaries at the next adjacent holes equals the instantaneous size of the pupil. At the same time, the eye is not overburdened, because even through the parts of the holes in the holes, which are between the holes, the signs of the picture and the objects can also be recognized. Sharp vision improves the eyesight of the amblyopic eye and the amblyopia is treated after training. Besides, in front of such gap filter glasses even little children do not get scared;
• - Because the gap filter panel is made of a thin material (about 0.15-0.3mm), the eye can see well through various holes in the gap filter panel, also through the side holes, because all the light entry openings for the eye in this case remain without reductions ;
• - Since the gap filter panel is made of a not fully transparent (about 20-50 percent) colored material, there is the possibility to those affected, especially the Glaukombetoffenen to use such color with such translucence of the material that best corresponds to the photosensitivity of the eyes and at the same time enable the sharp vision.

According to claim 2, it is advantageous that each gap filter aperture has two hole size ranges is provided, wherein in a range of the hole diameter is about 0,2-0,5 mm and in another - about 0,6-0,9mm, which according to the type of ametropia (myopia, Far-sightedness) from above or from below can arrange. The amblyope Eye gets the opportunity to see sharply both in the distance and in the near and thereby the visual acuity improve and treat amblyopia faster. Similar The glaucoma and other people with visual acuity get the benefits corresponding hole sizes the eyes, dependent of the type of ametropia, to be able to adjust.

According to claim 3, it is advantageous that the gap filter aperture made of soft material, because this eliminates the possible injuries in children, when the gap filter panel accidentally spoiled is.

• – weil der Grund der Amblyopieentwicklung, der von mir entdeckt ist, besteht darin, dass mindestens eine Fläche, mindestens eines optischen Elementes des Auges keine richtige geometrische Form hat (DE 10 2004 027 464.9) oder mindestens ein optisches Element keine gleichmäßige optische Brechkraft hat, kommen die von den Bildern reflektierte Lichtstrahlen in verschiedene Punkte der Netzhaut und besetzen eine große Fläche, die keine richtige geometrische Form hat und wesentlich größer ist als die Fläche der Fovea. Dadurch kann das Auge nicht scharf sehen, sogar wenn man für das Auge ein Korrekturglas versorgt. Auch eine Lupe kann nicht in bedeutendem Maße den Einfluss der unrichtigen geometrischen Form der optischen Augenelemente (oder der ungleichmäßigen optischen Brechkraft mindestens eines optischen Elementes) kompensieren und alle Lichtstrahlen nur auf die Fovea sammeln, oder auf eine andere kleine Fläche (wenn die Fovea zerstört ist), die mit der Fläche der Fovea kommensurabel ist. Das Auge kann durch ein Korrekturglas (eine Lupe) die vergrößerte Zeichen (Buchstaben) leichter erkennen, aber die vergrößerte Zeichen bleiben für das Auge sowieso verschwommen. Wenn das Auge durch die Lückenfilterblende schaut, kommen die Lichtstrahlen aus der Beobachtungsrichtung des Bildes gleich in die Fovea oder in eine andere kleine Fläche, wenn die Fovea zerstört ist, die nicht größer als die Fläche der Fovea ist. Das Auge sieht das Bild scharf. Dadurch wird die Fovea (ein anderer Punkt der Netzhaut an der Grenze der Fovea) entwickelt und die Amblyopie wird im großen Maße behandelt. Kinder können die Lückenfilterbrille bis einige Stunden pro Tag benutzen (nachdem das Kind gewöhnt ist). Die Erwachsenen können diese Sehvorrichtungen beim Lesen, am Komputer oder beim Fernsehen so lange benutzen bis sie keine Müdigkeit bekommen.

The treatment of amblyopia and the improvement of visual acuity, especially in patients with glaucoma, can thus be explained as follows:

• Because the reason of amblyopia development discovered by me is that at least one surface, at least one optical element of the eye, does not have a correct geometric shape (DE 10 2004 027 464.9) or at least one optical element does not have a uniform optical power, The rays of light reflected from the images come into different points of the retina and occupy a large area, which does not have a correct geometric shape and is much larger than the area of the fovea. As a result, the eye can not see clearly, even if one supplies a correction lens for the eye. Also, a magnifying glass can not significantly compensate for the influence of the incorrect geometric shape of the optical ocular elements (or the uneven optical power of at least one optical element) and collect all the light rays only on the fovea, or on another small surface (when the fovea is destroyed ), which is commensurable with the area of the fovea. The eye can more easily recognize magnified characters (letters) with a corrective lens (a magnifying glass), but the magnified characters are blurred to the eye anyway. When the eye looks through the gap filter aperture, light rays from the viewing direction of the image immediately enter the fovea or other small area when the fovea, which is no larger than the area of the fovea, is destroyed. The eye sees the picture sharp. This will develop the fovea (another point of the retina at the border of the fovea) and treat the amblyopia to a great extent. Children can use the gap filter glasses for a few hours a day (after the child is used to it). Adults can use these visual devices while reading, at the computer or watching TV until they do not get tired.

The light screen ( 7 ) is also made from a non-translucent (about 20-30 percent) material, which is particularly useful for people with glaucoma, because it allows avoiding possible eye strain.

embodiment

Of the Innovation object is exemplified with reference to the drawings, without to limit the protection claim.

It shows:

1 a representation of a gap filter glasses (it shows the holes on a large scale). For the right healthy eye is only a light screen ( 7 ), which has about 2/3 of the Brillenoffnugsbreite (l).

2 a section along the line 1, according to 1 ,

3 a plan view of a gap filter glasses (it shows the right half).

A device according to 1 . 2 and 3 contains a spectacle frame ( 4 ) and two gap filters ( 1 ), which are pulled out with the possibility and set after the rotation to 180 ° again in the spectacle frame, are movably mounted. The position of each gap filter aperture can be easily changed to fit the particular hole area ( 2 or 3 ) from above or below, as the amblyope eye needs. It shows as an example the position of the gap filter aperture, which corresponds to the need of the short-sighted left eye: the smaller holes through which the eye looks into the distance are from above. For a farsighted eye, the position of the gap filter aperture should be reversed, as shown by the arrows (a). For this you need to push the gap filter panel up, then turn it over and set it again. For the healthy (right) eye is a light screen ( 7 ), which has 2/3 of the eyeglass opening (l). In the case when the other eye is also ill-considered, the light screen is used together with the other gap filter aperture.

glaucoma sufferers can do the same when an eye sees worse.

Around the victims can see with both eyes at the same time and by developing both eyes simultaneously, is in the gap filter glasses the possibility the change the distance between the holes intended. Therefore the width of the eyewear cutout (s) is about 3mm larger than the width of the gap filter aperture (M). The affected person can move one or both gap filters to the left (to right) push until the distance between the corresponding holes with the distance between the pupils is the same.
