The patient who notes binocular diplopia may indicate that horizontal, vertical, or cyclorotary components are present. Although the single binocular visual field provides an indication of the area which is free of horizontal and vertical diplopia, it does not assess cyclorotary diplopia. A simple modification of the single binocular visual field which allows determination of the clinical significance of the cyclorotary component of diplopia is presented. Reproducible information is easily obtained, assisting in patient follow-up and management.
