A comparison of objective accommodative response (as measured by a retinoscope), to the subjective accommodative response (as measured by cross cylinders), as convergence is postured inside and outside the plane of regard

Abstract

The purpose of this study was to compare the subjective accommodative posture as measured by a 20" cross cylinder to the objective accommodative posture as measured retinoscopically at 20". Also to compare the subjective accommodative posture as convergence was postured 2 meter angles (12 prism diopters) inside and outside the plane of 20" to the objective accommodative posture with the same change in convergence. It was also thought desirable to determine if the group of subjective findings were statistically predictable for the battery of objective tests.
