Rescued eye and yet in danger – ocular melanoma

Sunday, July 5th, 2015

Eine 50 jährige Frau verlor ihr linkes Auge wegen einer ausgedehneten Netzhautablösung. Am besseren rechten Auge: doppeltes Pech! Sie hatte ein Melanom! Das Auge konnte gerettet werden.  Es wurde erfolgreich mit Protonen bestrahlt, der Tumor schrumpfte. Der Visus verblieb um 0.5, manchmal sogar 0.7, wenn die Sicca nicht ausgeprägt war. Nach Jahren trat dann leider Visusverlus auf 0.3 und Metamorphopsien. Was war passiert?

A female had lost her left eye because of an extended retinal detachment. In her right eye, she had a melanoma, that was cured with proton beam radiation therapy. Years later, loss of visual acuity occured, but why?

Floating in 3D-GETOCT 3D fanatasy is for you!

Thursday, January 8th, 2015

Sie denken, das, was Ihre Augen Ihnen zeigen, ist wahr? Wirklich? Die richtige Welt ist aber gar nicht so, wie wir sie sehen. Die Welt “innen und aussen” ändern sich stets und Sie müssen eine Verbindung herstellen.

Schauen sie meinen Film und halten Sie den Atem an. Diese 3D GETOCT Phanatasie ist für Sie! 3D Phantasien sind “in” dieses Jahr. Schauen Sie, was vor Ihren Augen fliegt und sogar in Sie hineinrast, das es gar nicht gibt. Ihr Hirn betrügt Sie. Beachte: nichts, was Sie sehen ist wirklich wahr.

Genau so ist es mit den OCT-Bildern als Augenarzt: das Hirn diagnostiziert die Bilder sofort und Sie können sich vor einer “Diagnose” fast nicht wehren. Darum gibt es bei allen OCT-Bildern einen guten Tipp von Dr. Maloca: zurücklehnen, geniessen und warten bis die “OCT-Wahrheit” erscheint!

>Geniessen Sie (mit einer Rot-Cyan-Brille) und lachen Sie über Ihre Augen und Ihr Hirn und über dieses Wunder. /Watch (with Red-Cyan glasses)  and hold your breath. Just enjoy and smile about your eyes and brain showing you a miracle.

Ihr Dr. med. Peter Maloca, Luzern/Augenklinik Universität Basel

You think, what your eyes are showing you is true? Really? The world seems not to be what it is. The “inner” and “outer” world change and you have to connect.

This GETOCT 3D fanatasy is for you. 3D fantasies are in this year. Watch, what is passing before your eyes, that even does not exist. Your brain is fooling you. Realize: it is not really true what they say to you.  Still, this is the stuff your world is made off.

Not every OCT image is “true”.  The brain diagnoses the OCT  images immediately and you can almost not defend yourselve against a “diagnosis”. But there is a good and simple tipp from Dr. Maloca: sit back, relax and wait and wait until the ” OCT truth” appears!

The Original OCT – First OCT Course anno 2003…old but not dusty!

Friday, February 7th, 2014

>English version find below

Es ist unglaublich und wunderschön zu sehen, wie OCT zum Segen der modernen Augenmedizin geworden ist. Die wirklich interessante Geschichte begann circa 2003, wo mit dem ersten kommerziell verfügbaren Time-Domain-OCT Stratus eine neue Epoche in der augenmedizinischen Diagnostik und Therapie eingeläutet wurde. Für den Patienten stand erstmals eine schonende und berührungsfreie Methode bereit, die ohne Nebenwirkungen beliebig oft wiederholt werden konnte.

Follow the first OCT presentation:

Der Augenarzt betrat zuerst einen völlig neuen Mikrokosmos, obwohl aus histo-pathologischen Studien schon sehr viel bekannt war. Dennoch galt es mit Fleiss und Ausdauer, Erfahrungen zu sammeln, um die beste Diagnostik und Therapie zu finden. So haben beide Seiten von der heute etwas angestaubten, aber in den Grundzügen noch stets modernen Time-Domain-Technologie profitiert und viele Augen konnten gerettet werden.

Als Erinnerung an diese “gute alte OCT-Zeit” wird hier der allererste Vortrag zu “OCT und Auge” veröffentlicht. Die Krankheiten haben in all den Jahren nichts an ihrer Aktualität und Gefährdung verloren. Doch gelingt es heute immer besser, die gefährliche Situation schneller und effektiver zu meistern. Schon 2003 zeigte sich eine neue Bildsprache, die mit den OCT-Geräten der neuesten Spectral-Domain-Technologie weiter verfeinert wurde. Dem Augenarzt erschliesst sich diese manchmal eigenwillige Sprache nicht sofort, sodass die “Originale OCT-Präsentation anno 2003″ auch heute Prinzipen zur richtigen Diagnostik aufzeigen kann. Viele interessante Minuten wünscht Dr. med. Peter Maloca, Luzern/University Basel.

It’s amazing and wonderful to see how OCT has become a blessing of modern ophthalmology. The really interesting history began circa 2003, where it was heralded with the first commercially available time-domain OCT Stratus, a new era in eye care diagnostics and therapy. The eye doctor first entered a completely new microcosm, even though it was already very much known from histopathological studies. Nevertheless, it was hard work and perseverance to gain the top-experience to find the best diagnosis and treatment. So both sides have benefited from the “2003 modern time-domain technology” and many eyes were saved.

As a reminder to those “good old OCT-time” , the very first lecture will be published here in its original version. The diseases have lost in all the years none of their risks. But they can be defined today more quickly and effectively. In 2003 there was a new “visual language” introduced , which has been refined with the newer OCT devices as with the latest spectral domain technology. The eye doctor does not understand this sometimes idiosyncratic language immediately, so that the “Original OCT presentation from 2003″ can reveal principles for proper diagnosis even today. Many interesting minutes wishes Dr. Peter Maloca, Lucerne /University Basel.

Thursday, January 23rd, 2014

>View the program:  Program_OCT Course_Basic Swiss Eye Science Course 2014

The result of the evaluation shows to which high level the Swiss OCT-basic course has moved again in its second year. The OCT course was focused on the knowledge and skills that the modern eye doctor needs in his daily carefully work with his patients.

Many OCT-images and OCT-movies showed how exciting and eventful a career of an ophthalmologist can be in saving the vision of his entrusted patients. In addition to the general OCT-theory there was the opportunity for a hands-on on some current OCT scanners, so that the technical skills were trained under experienced eyes, too. The relatively small size of the group allowed exciting and active discussions, so, boredom was a foreign word for these two days. At the end, everyone felt very good on a higher level, surrounded by a fascination for the medicine of today, bringing  a great advantage to the patient.

>What can a trainer say, if an evaluation for an OCT course could be scored best with 6 points, and the course finally is rated more than a  “6″, just excellent? This is a real perfect result and satisfaction for all.  A big “thank you” to all participants who were not only involved, but have contributed with many questions to the glance of this unique OCT event in Switzerland. Kind regards, Dr. med. Peter Maloca, Biel-Bienne 2014.

Swiss Eye Week 2014 OCT Course

Sunday, January 5th, 2014

>View the program: Program_OCT Course_Basic Swiss Eye Science Course 2014

OCT (optical coherence tomography) resembles ultrasound but uses harmless laser light. Coherent light waves produce cross-sectional images of retinal tissue).
In a novel, very interactive course the physical basics of OCT terms, failure modes and settings will be discussed. A second module offers hands-on exercises in small groups at OCT scanning systems. A third module supports networking among participants to build reliable interactions and share their experiences even far in the future.  The aim of the course is that each participant can perform an OCT independently and collect findings for a correct diagnosis.
