METHOD AND DEVICE FOR TESTING BINOCULAR STEREOSCOPIC VISION Russian patent published in 2008 - IPC A61B3/08 

FIELD: medicine; medical engineering.

SUBSTANCE: method involves showing concave face mask as test object. Distance to the test object is increased in discrete steps from 0.2 to 6 m in tachystoscopic exposures between test object steps of fixed test object. Luminous ring stimulus is shown after each exposure. Individual distance values associated with visual effects occurred are measured. Distance changes dynamics is studied for distances required for doing reverse test object inversion in several repeating actions of test object approaching and moving away. Inversion regularity is studied in carrying out active approaching- moving away of testee to the test object. Device has two guides and carriage with test object, movable by means of engine along them. The test object is enclosed into light-tight box having illumination inside it, optimum for creating illusions, independent of its movements. Slit shaped as the mask and ring circumscribing the slit and becoming radiant at given moments are available on luminous panel. Head holder fixed at the device end, measuring ribbon attached to carriage with its ends and having ring connection over bobbins available on the guide member ends. Ribbon scale division in front of fixed pointer in chamber isolated for researcher at the device end shows distance from testee eyes to the test object. Remote control desk is also available for controlling device operation. Testee button is mounted outside for stopping test object carriage movement. The device enables one to vary test object presentation mode, change short exposure durations, continuously showing the continuously approaching test object.

EFFECT: enhanced effectiveness in determining regularity of binocular inversion versus intensity and duration of binocular stimulation; high accuracy in determining individual typological specific changes in intensity and duration of binocular stimulation.
