Summary

This prospective study investigated the validity and test-retest reliability of stereopsis test using head-mount display (HMD). Contour-based circles (crossed disparity: 1,960 to 195 arc of seconds(arc secs)) were generated as separate images on a high resolution phone display (Galaxy S7; Samsung, Suwon, Korea) using a HMD (Galaxy Gear VR; Samsung, Suwon, Korea). Two images were independently projected to each eye as graded circles with random dot background. While the position of the stimulus changed from among 3 possible locations, the subjects were instructed to select the circle with disparity by pressing the corresponding position on a keypad. The results of the new HMD stereotest were compared to those from standard Randot and TNO stereotests.
