Abstract

Background

The development of a functional retinal prosthesis for acquired blindness is a great challenge. Rapid progress in the field over the last 15 years would not have been possible without extensive animal experimentation pertaining to device design and fabrication, biocompatibility, stimulation parameters and functional responses. This paper presents an overview of in vivo animal research related to retinal prosthetics, and aims to summarize the relevant studies.

Methods

A Pubmed search of the English language literature was performed. The key search terms were: retinal implant, retinal prosthesis, artificial vision, rat, rabbit, cat, dog, sheep, pig, minipig. In addition a manual search was performed based on references quoted in the articles retrieved through Pubmed.

Results

We identified 50 articles relevant to in vivo animal experimentation directly related to the development of a retinal implant. The highest number of publications related to the cat (n = 18).

Conclusion

The contribution of animal models to the development of retinal prosthetic devices has been enormous, and has led to human feasibility studies. Grey areas remain regarding long-term tissue-implant interactions, biomaterials, prosthesis design and neural adaptation. Animals will continue to play a key role in this rapidly evolving field.

Ophthalmika in der Schwangerschaft

Die Verwendung von Ophthalmika in der Schwangerschaft und Stillzeit stellt immer eine Off-label-Anwendung dar. Ein Einsatz von Arzneimitteln muss daher besonders sorgfältig auf sein Risiko-Nutzen-Verhältnis bewertet werden. In der vorliegenden …

Operative Therapie und Keimnachweis bei endogener Endophthalmitis

Vitrektomie Originalie

Die endogene Endophthalmitis ist eine hämatogen fortgeleitete, bakterielle oder fungale Infektion, die über choroidale oder retinale Gefäße in den Augapfel eingeschwemmt wird [ 1 – 3 ]. Von dort infiltrieren die Keime in die Netzhaut, den …

Bakterielle endogene Endophthalmitis

Vitrektomie Leitthema

Eine endogene Endophthalmitis stellt einen ophthalmologischen Notfall dar, der umgehender Diagnostik und Therapie bedarf. Es sollte mit geeigneten Methoden, wie beispielsweise dem Freiburger Endophthalmitis-Set, ein Keimnachweis erfolgen. Bei der …

So erreichen Sie eine bestmögliche Wundheilung der Kornea

Die bestmögliche Wundheilung der Kornea, insbesondere ohne die Ausbildung von lichtstreuenden Narben, ist oberstes Gebot, um einer dauerhaften Schädigung der Hornhaut frühzeitig entgegenzuwirken und die Funktion des Auges zu erhalten.
