Abstract

The method of colouring microtom cuts of eyeballs with surgically implanted artificial lenses which do not destroy them uses implants which do not dissolve but which are preserved. The position of contact between the artificial lens and the removed tissue part can be accurately located microscopically. USE/ADVANTAGE - In eye pathology. Enables spatial relationship of artificial lens to removed tissue to be detected non-destructively.

Description

Gattung des AnmeldungsgegenstandesGenre of the object of registration

Die Erfindung gehört zur Augenpathologie, wie sich aus dem folgenden ergibt:The invention belongs to eye pathology, as can be seen from the results in the following:

An der Oberfläche und in der weiteren Nachbarschaft der verschiedenen Teile intraokularer Linsenimplantate treten häufig pathologische Vorgänge auf, die bisher u. a. deshalb nicht mit Sicherheit als Reaktionen auf das Kunstlinsenim­ plantat nachzuweisen waren, weil die Berührungsstellen des kranken Gewebes mit der Kunstlinse noch nicht mikroskopisch sichtbar gemacht werden konnten. Die Sichtbarmachung der tatsächlichen Berührung von Linse und Gewebe im Mikroskop setzt voraus, daß das Präparat nichr nur das kranke Gewebe, sondern auch den mitgeschnittenen Kunstlinsenteil enthält. On the surface and in the wider neighborhood of the different parts of intraocular lens implants often pathological processes that have hitherto a. that's why not with certainty as reactions to the artificial lens were to be demonstrated because the contact points of the not yet microscopic with the artificial lens could be made visible. The visualization of the actual contact of lens and tissue in the microscope assumes that the preparation is not just the diseased tissue, but also contains the recorded artificial lens part.  

Stand der Technik und dessen KritikState of the art and its criticism

Der aus Polymethacrylsäuremethylester (PMMA) bestehende Kunststofflinsenanteil des Mikrotomschnitts wird bei den herkömmlichen Färbeverfahren durch das dort verwendete Xylol aufgelöst. Dadurch erscheint das intraokulare Lindenimplan­ tat (IOL) im histologischen Präparat optisch als leere Flä­ che. Da die Linse nicht sichtbar ist, kann man deren Berüh­ rung mit dem kranken Gewebe nicht sehen. Einen Ursachenzu­ sammenhang zwischen Berührung und Entzündung konnte man da­ her bislang mangels anderer exakter Nachweise nur vermuten.The one consisting of polymethacrylic acid methyl ester (PMMA) Plastic lens portion of the microtome section is used in the conventional dyeing process using the xylene used there dissolved. This causes the intraocular linden implant to appear did (IOL) optically in the histological preparation as an empty area che. Since the lens is not visible, you can touch it with the diseased tissue. A cause there was a connection between touch and inflammation hitherto only suspect in the absence of other precise evidence.

Aufgabetask

Die räumliche Zuordnung des IOL zum entzündeten Gewebe konnte nur dann sichtbar und damit pathologisch und diagnostisch nachweisbar werden, wenn eine Färbemethode für den Mikrotom­ schnitt gefunden wurde, die die mitgeschnittene IOL nicht zerstört.The spatial assignment of the IOL to the inflamed tissue could only then visible and thus pathological and diagnostic become detectable if a staining method for the microtome the recorded IOL was not found destroyed.

Lösungsolution

Die Aufgabe wird durch folgendes, hier zum Patent angemelde­ tes Verfahren gelöst:The task is patented by the following, here Process solved:

  • 1. Das enukleierte Auge wird zunächst 72 Stunden in 10% igem Formalin (Merck) fixiert.1. The enucleated eye is initially 72 hours in 10% formalin (Merck) fixed.
  • 2. Vor der weiteren Aufbereitung im Autotechnicon (aufstei­ gende Alkoholreihe - Chloroform - Histowachs) werden die Augen 24 Stunden gewässert. 2. Before further processing in the Autotechnicon (ascending alcohol series - chloroform - histo wax) Eyes watered for 24 hours.  
  • 3. Vor der Eingabe in das Autotechnicon wird der Bulbus mit einer Kanüle in der hinteren Hälfte eröffnet, damit alle Präpariermittel auch das Augeninnere erreichen.3. Before entering into the Autotechnicon, the globe is included a cannula opened in the back half so everyone Preparations also reach the inside of the eyes.
  • 4. Im Autotechnicon wird das Intermedium Chloroform durch Zedernholzöl ersetzt. Die Verweilsdauer darin ist auf zwei mal vierundzwanzig Stunden zu erhöhen.4. In the Autotechnicon, the intermediate medium is chloroform Cedarwood oil replaced. The dwell time in it is on increase two times twenty-four hours.
  • 5. Nach Halbierung des Bulbus oder Anbringen einer Öffnung im Bulbus wird dieser in Histowachs eingebettet. Beim Einbetten werden die Augen nach ihrer Längsachse ausge­ richtet.5. After halving the globe or making an opening in the bulb it is embedded in histo wax. At the Embed the eyes out along their long axis judges.
  • 6. Dann werden 5-my-dicke Mikrotomschnitte angefertigt, die auf mit Eiweißglycerin eingestrichene Objektträger im Wasserbad aufzuziehen und anschließend zu strecken sind. Das Schneiden erfolgt nicht ganz bis zur Mitte der IOL, da sonst die Gefahr besteht, daß das IOL aus dem Ein­ bettmaterial herausgerissen wird.6. Then 5 micron thick microtome sections are made on slides coated with protein glycerin in the Pull up the water bath and then stretch it. The cutting is not done all the way to the middle of the IOL, otherwise there is a risk that the IOL from the one bed material is torn out.
  • 7. Nach dem Strecken werden die Präparate mit der Objekt­ seite nach unten für ca. 18 Stunden auf Filterpapier in den Wärmeschrank bei 56°C gelegt, damit schon jetzt ein Teil des Histowachses entfernt wird. Das restliche Wachs wird durch Einlegen der Präparate für 6 Stunden in Benzin herausgelöst.7. After stretching, the specimens with the object side down for about 18 hours on filter paper put the oven at 56 ° C, so now part of the histo wax is removed. The rest Wax is in for 6 hours by placing the preparations in Petrol extracted.
  • 8. Sodann werden die absteigende Alkoholreihe bis Alkohol abs. und die eigentlichen Färbelösungen (PAS oder H.E.) durchlaufen.8. Then the descending alcohol row to alcohol Section. and the actual staining solutions (PAS or H.E.) run through.
  • 9. Vor dem Eindecken mit Eukitt werden die aus dem Alkohol abs. kommenden Präparate vorsichtig einen Augenblick lang in Xylol getaucht, um die Verträglichkeit des Ge­ webeschnittes mit dem Einschlußmittel Eukitt sicherzu­ stellen.9. Before covering with Eukitt, the alcohol is removed Section. coming preparations carefully for a moment long immersed in xylene to check the compatibility of the Ge weave cut with the inclusion agent Eukitt put.
Erzielbare VorteileAchievable advantages

Vorteile erwachsen aus der Erfindung sowohl für die Augen­ diagnostik wie auch für die Linsenproduktion, hängt doch die Verbesserung des Materials und der Form der jetzt verwende­ ten Linsenimplantate entscheidend davon ab, daß zunächst deren pathogene Wirkung naturwissenschaftlich zureichend nachzuweisen ist. Prima vista mag die Erfindung weniger bedeutend erscheinen, als sie
a) wissenschaftlich und
b) wirtschaftlich tatsächlich ist.
Advantages arise from the invention both for eye diagnosis and for lens production, but the improvement of the material and the shape of the lens implants now used depends crucially on the fact that their pathogenic effect is first scientifically proven. Prima vista, the invention may seem less important than it
a) scientifically and
b) is economically actual.

Zu a) Die Zahl der Linsenimplantationen ist weltweit sehr hoch (Staroperationen etc.). Diese chirurgischen Eingriffe haben leider gelegentlich zelluläre Reaktionen zur Folge, die den Implantationserfolg gefährden, weil die Ur­ sachen noch nicht eindeutig geklärt sind. Die Erfindung macht den exakten Ursachennachweis möglich.To a) The number of lens implantations worldwide is very high high (star operations etc.). This surgical Unfortunately, interventions occasionally lead to cellular reactions Consequence that endanger the success of the implantation because the original things have not yet been clearly clarified. The invention makes the exact cause evidence possible.

Zu b) Damit ist auch der technologische Aspekt der Erfin­ dung ersichtlich, also die Bedeutung für die For­ schung und Produktion zum Material und zur Formgebung der Kunstlinsen, die von vielen Institutionen und Firmen im In- und Ausland betrieben wird.To b) This is also the technological aspect of the inven can be seen, i.e. the meaning for the For research and production on the material and shape of the Artificial lenses used by many institutions and companies in and abroad.

Auf die erzielbaren Vorteile ist auch die hier zugrundege­ legte Bewertung der Erfindung zu beziehen, die mit 100 000,- DM jedenfalls nicht zu hoch angesetzt erscheint. Weitere Parameter für die Wertberechnung können unsererseits nicht beigebracht werden.The achievable advantages are also the basis here submitted to refer to the invention with 100 000, - DM does not appear to be set too high in any case. Further We cannot use parameters for the value calculation be taught.
