Description LANG STEREOTEST® I-R High and modern quality Improved optical quality of test cards thanks to modern digital and lenticular technology. Homogeneity Increased homogeneity of the dot pattern and reduced single-eye recognition. Rounded corners New surface lamination and laser cutting. Correct application Schematic drawing and brief instructions on the back. MDR 2017/745 compliance LANG STEREOTEST® represents today’s standard of random dot stereo tests without the need of 3D glasses, with very high sensitivity and specificity for stereopsis. The test combines random dots and a lenticular grid surface for quick screening of binocular vision in all groups of age, including very young children. While the test card is presented at reading distance, the patient is asked about what he sees and his eye movements are being observed. Recognition of figures is only possible if the person has full global stereopsis, while patients with amblyopia and (even small angle) strabismus fail the test. LANG STEREOTEST® I-R shows three stereo figures with disparities of 1200, 600 and 400 arcsec.
