METHOD OF SPACE ORIENTATION CAPABILITY ASSESSMENT FOR OPHTHALMOLOGICALLY DISABLED PERSONS Russian patent published in 2009 - IPC A61F9/08 A61B10/00 

FIELD: medicine.

SUBSTANCE: invention concerns medicine, particularly social medical examination for eye diseases, and can be applied in quantitative assessment of spatial orientation capability of ophthalmologically disabled persons. Patient moves around room with sound sources hung on walls and activated in random order, finds the sources and switches them off. Spatial orientation is assessed by the formula: where Ko is orientation coefficient, n is the number of correctly located and deactivated sound sources; N is the general number of sound sources = 8; t is given time = 60 seconds. Depending on the obtained Ko disability degree of spatial orientation is defined, at: Ko =100% spatial orientation capability is not disabled; Ko = up to 80%% - 1 degree of spatial orientation limitation; Ko =79-50%% - 2 degree of spatial orientation limitation; Ko =49% and under - 3 degree of spatial orientation limitation.

EFFECT: determination of vital function category by spatial orientation for ophthalmology cases by quantitative assessment.
