Evaluation of the Relationship Between Aniseikonia and Stereopsis Using a New Method.

ABSTRACT:

Purpose

To investigate the influence of induced aniseikonia on stereopsis measured by contour-based and random-dot-based stereograms using a new method.

Methods

Unlike previous studies in which aniseikonia was induced using magnifiers, which potentially influenced the position of the test symbols in the half-view, here the image was magnified while maintaining each test symbol's central position within the half-view. A phoropter and two 4K smartphones were used to measure stereopsis in seventeen young adults aged 20-28 years old. Stereopsis was tested using both contour-based and random-dot-based stereograms under overall or meridional aniseikonia with magnifications ranging from 2.5 to 30%. Repeated measures ANOVA was used to evaluate the effect of aniseikonia on stereopsis
