LANG II TEST

LANG II TEST

LANG'S STEREOTEST® represents the current standard of stereotests based on random dots, without the need for 3D glasses and with high sensitivity and specificity for stereopsis.

The test combines random dots and a lens grating and is designed for rapid screeening of binocular vision in all age groups, including very young children. The card is presented at a reading distance and the patient is asked what they see, while eye movements are observed.

Figure recognition is only possible for subjects with full stereopsis, while patients with amblyopia and strabismus (even at a reduced angle) fail the test.

The STEREOTEST® II DI LANG has four stereograms with disparities of 600, 400, 200 and 200 arcsec, of which only one is also visible monocularly.
