Zusammenfassung

Hintergrund

Die Anzahl der in Deutschland durchgeführten Hornhauttransplantationen stieg in den letzten Jahren stetig an. Ursächlich ist u. a. ein früherer Operationszeitpunkt, v. a. aufgrund der Entwicklung von schonenderen Verfahren für hintere lamelläre Hornhauttransplantationen. Zur ursächlichen und etablierten Therapie von durch Endothelpathologien verursachten Hornhauterkrankungen stehen derzeit lediglich perforierende oder lamelläre Hornhauttransplantationen zur Verfügung.

Ziel der Arbeit

Diese Arbeit legt verschiedene translationale Strategien zur Modifikation des Hornhautendothels unter Verwendung von Nanopartikeln dar.

Ergebnisse

Nanopartikelbasierte Strategien zur Optimierung des Hornhautendothels erstrecken sich auf folgende Anwendungsgebiete: 1. während der Kultivierung von Spenderhornhäuten in Kulturmedium, 2. im Rahmen von Injektionen von einzelnen von Spenderhornhäuten gewonnenen Endothelzellen, 3. zur Behandlung von patienteneigenen Endothelzellen zur Vermeidung von Transplantationen.

Schlussfolgerungen

Es bestehen diverse translationale Ansätze zur Verbesserung oder Vermeidung von Hornhauttransplantationen. In der kommenden Dekade wird mit etablierten Alternativen zur Hornhauttransplantation zu rechnen sein.

Abstract

Background

The number of corneal transplantations has increased in Germany in recent years. One reason is an earlier time point of surgery due to less invasive posterior lamellar grafting techniques. To date, penetrating and lamellar corneal transplantations are the only established therapeutic options to treat corneal diseases resulting from endothelial cell pathologies.

Aim

This review article provides an insight into nanoparticle-related translational strategies to improve or to avoid corneal transplantation.

Results

Nanoparticle-based strategies for optimization of the corneal endothelium have different fields of application: 1. during donor cornea cultivation in culture medium, 2. for single cell injection therapies and 3. to treat the patients’ own endothelium in an effort to avoid transplantation.

Conclusion

Several translational concepts exist to improve or to avoid grafting of a donor cornea. The coming decade will provide established alternatives to conventional corneal transplantation.
