Computer-Based Analysis of Visual Fields

Age-Related Norms for the Central Visual Field

Abstract

This paper will fulfill two purposes:

A) To describe ways, means, and advantages of using computers to analyse two-dimensional clinical data (e.g. photographs, charts) so that the reader will have a clearer understanding of these methods and perhaps start considering applying them in practice.

B) To present the results from a study of the central visual fields of 129 normal patients aged 10 to 70 years. These results are presented as average central fields for indivi­dual age groups ( 15, 25, 35, 45, 55, 65 years) so that the reader may compare a given patient's central field data to a norm for that patient's age group.
