Based on the anatomical section of an emmetropic eye a spherical or circular fundus is developed by application of a mathematical-statistical method resulting in an optimal approach to the anatomy. The same method is applied to a fundus which is derived by mere computation exclusively from the data of the schematic eye. The results of both methods coincide remarkably well. In this way a schematic fundus is defined as circle with 11.6 mm radius. Its center has a distance of 12.8 mm from the anterior corneal vertex. The applicability of this fundus is discussed.
