A NEW APPROACH TO GENERATING PSEUDOISOCHROMATIC PLATES

Pseudoisochromatic plates have been used for detecting dichromacy (especially protanopia and deutanopia) for almost a century. This method, although widespread due to its simplicity and relatively low examination cost, is often criticized because of potential ambiguity and inaccessibility for certain groups of patients. In this article author analyzes different versions of currently used pseudoisochromatic plates and introduces a tool for generating customized plates in order to detect different types of dichromacy in certain user groups.
