Random-dot stereograms highlighted a problem for stereopsis, the correspondence problem. There are basically two methods to test for aniseikonia: the space eikonometric method and the direct comparison method.15,16 The space eikonometric method is based on binocular space perception, while the direct comparison method is based on directly comparing perceived image sizes between the two eyes.. "The neural mechanism of binocular depth discrimination". This is the only convenient and efficacious route of administration (apart from Intravenous therapy ) of nitroglycerin to a patient suffering chest pain from angina pectoris. Human embryology (Third.). One of the advantages of this forced choice method compared to a method of adjustment (such as used in the Basic Aniseikonia test and the 'New' Aniseikonia Test) is that the forced choice method also provides information about the consistency/accuracy of the measurement..
