title: Stereopsis measured by random-dot patterns--a new clinical test.
abstract: Comparative measures are presented of stereo-acuity by random-dot stereograms using a phase difference haploscope and a Titmus stereogram. Using two groups of fifteen subjects each, one with full binocular vision and the other of small-angle strabismic amblyopes, greater discrimination between subject groups was found with the random-dot stereograms. It is concluded that random-dot stereograms produced by crossed Polaroid would be a more effective clinical means of determining stereo-acuity.
