RELATIONSHIPS BETWEEN ANISEIKONIA AND AMETROPIA: FROM A STATISTICAL STUDY OF CLINICAL CASES

Abstract

Abstract INTRODUCTION The importance of aniseikonia as an etiologic factor in certain visual disorders has been proved by previous investigations,1 but there are still many misconceptions2 concerning the relationships between aniseikonia and ametropia. The object of this paper is to clarify these misconceptions by presenting a statistical analysis of the cases of 283 patients who have received definite relief from ocular discomfort by the correction of aniseikonia. During the early years of the development of the research on aniseikonia the patients who were examined at The Eye Clinic of the Dartmouth Medical School constituted what might be called a highly selected group.1a At least 90 per cent of them were referred to The Eye Clinic because all other procedures used had failed to give relief or reveal any organic cause for their discomfort. In general, the symptoms reported by these patients included functional disturbances, such as asthenopia, photophobia References 1. (a) Carleton, E. H., and Madigan, L.
