Innovative Technologien für optimiertes künstliches Sehen

Zusammenfassung

Trotz deutlicher Fortschritte in der Therapie schwerer Augenerkrankungen können bestimmte Formen der Erblindung bis heute nicht geheilt oder gebessert werden. Dazu gehört beispielsweise die Retinitis pigmentosa, eine erbliche Degeneration der Photorezeptoren. Technologieansätze mit implantierbaren Sehprothesen, deren Prinzip in einer elektrischen Stimulation verbleibender Nervenzellen in der Retina oder im Cortex, wurden bereits bei einer Reihe von Patienten mit begrenzten Ergebnissen erprobt. Neue Befunde in der Biologie der Erkrankungen aber auch neue technologische Entwicklungen machen hier Hoffnung auf bessere Ergebnisse in der Zukunft.
