Abstract

Einer der faszinierendsten Aspekte der menschlichen visuellen Wahrnehmung ist die Fähigkeit, die Bilder der beiden Augen zu einem einheitlichen, räumlichen Wahrnehmungseindruck zu verschmelzen - einem Eindruck, bei dem Gegenstände sich plastisch von ihrem Hintergrund "abheben". Diese scheinbar mühelose Leistung erfordert ein einwandfreies visuelles Angebot in früher Kindheit. Störungen der Sehfähigkeit bei Babys und Kleinkindern, z. B. durch ungleiche Brechkraft der beiden Augen (Anisometropie), lichtundurchlässige Augenmedien aufgrund hängender Augenlider (Ptosis) oder angeborene Linsentrübung (Katarakt) können zu einem irreversiblen Verlust der Sehkraft auf einem oder beiden Augen führen. Fachleute sprechen in diesem Fall von Amblyopie, was soviel bedeutet wie "dumpfes Sehen"
