A Precision Instrument for the Clinical Measurement of Stereoscopic Acuity

Résumé

When tested by different methods, a patient's stereoscopic acuity is sel­dom the same. This raises the ques­tion as to which one gives the true stereoscopic acuity. To answer this, a programmable test for stereoscopic acuity was designed to serve as a test­ing standard. This is described and a comparative study with it and four other tests is reported.
