The LANG STEREOTEST I-R for binocular diagnostics and screening of disorders of stereoscopic vision in adults and children, for medical professionals.
Intended use LANG Stereotest I-R
The LANG-STEREOTESTS® I-R is used for rapid screening of stereopsis vision in all age groups from 6 months of age. Since loss of stereopsis is considered a key symptom of amblyopia (lazy eye), failure to recognise random dot stereograms may indicate a previously undetected, treatable disorder of binocularity (e.g., microstrabismus, anisometropia). LANG-STEREOTESTS have proven to be highly specific and highly sensitive for stereo vision. Thanks to the unique combination of random dots and a lenticular lens, no special glasses are needed, and the eye movements of the subject may be easily observed.
