Zusammenfassung

Die Retina ist der sensorische Anteil des Auges und die innerste der drei Schichten, die das Auge bilden. Die Netzhaut wandelt die optische Information der Bilder aus der Außenwelt in neurale Impulse um, welche das Gehirn verarbeitet, um die visuelle Wahrnehmung gewährleisten zu können. Man unterscheidet verschiedene topographische Regionen in der Retina: die Area centralis (zwischen den oberen und unteren temporalen Arterien), die Macula lutea (eine stark durch Lutein und Zeaxanthin pigmentierte Struktur), die avaskuläre Fovea centralis (die Zapfen erreichen hier die maximale Dichte), die periphere Retina, welche in Kontakt mit der Ora serrata steht und überwiegend mit Stäbchen besiedelt ist, sowie die Ora serrata (Übergangszone zum nicht pigmentierten Epithel der Pars plana).
