Die beste visuelle Information iiber Maculaprozesse gibt die dreidimensionale Spaltlampenbeobachtung des Fundus. Sie ist nur mit Zusatzglas moglich. Geo metrisch optische Dberlegungen zeigen folgendes: Wichtig ist sowohl ein geniigend groBer Projektionswinkel als auch ein aus reichendes Gesichtsfeld. Daher muB 1. die Pupille gut erweitert sein 2. die Zusatzlinse eine hohe Brechkraft haben 3. der Durchmesser, besonders bei + Glaseru, geniigend groB sein 4. der Abstand vom Auge bei Glasern moglichst klein sein (Kontaktglas) 5. die Spaltlampe ein moglichst helles Spaltbild erzeugen und einen kleinen Winkel zwischen Mikroskop und Beleuchtungseinrichtung zulassen. Ametropien beeinflussen die Abbildungseigenschaft der Zusatzglaser, daher lassen sich 6. hoheMyopien besser mit + Glas und 7. hohe Hyperopien besser mit Glas untersuchen.
