title: Examinations on the new lang test.
abstract: The New Lang-II stereopsis test employs, as compared to the Lang-I test, smaller disparities and a less dense arrangement of random dots. In 162 subjects the authors comparatively evaluated the results of the Lang-I and Lang-II tests. Ninety percent of subjects with normal binocular vision passed both tests without making any mistake (n = 127). However, about 70% of patients with microstrabismus failed both tests (n = 35). Little difference was found between the results of both tests.
