Abstract
The aim of this paper is to evaluate the role of interocular differences in retinal-image quality in stereoscopic depth perception. To characterize retinal-image quality, we took the Strehl ratio from a double-pass device. Stereopsis was quantified through maximum disparity using random-dot stereograms (RDS). Data were taken for 25 observers with ages ranging from 21 to 61 years. The results show a significant correlation between maximum disparity and interocular differences in the Strehl ratio: the lower interocular differences, the higher maximum disparity. No significant dependence with age was found.
