METHOD FOR DIFFERENTIAL DIAGNOSTICS TO DETERMINE SHAPE AND DEGREE OF INHERITED DISORDERS IN CHROMATIC VISION Russian patent published in 1998 - IPC

FIELD: medicine, ophthalmology, differential diagnostics. SUBSTANCE: patients are offered a red-colored test-object at angular value of 15.3 to 40.5 and a green-colored one at angular value of 11.5 to 25.5 and in patients who correctly accept red color in 15.3 to 27.8 range and green color within 11.5 to 17.6 range the light degree is predicted, and in patients who correctly accept red color within 28.5 to 40.5 range and green color within 15.8 to 25.5 range the middle degree of protanomalia and deuteranomalia could be predicted. Additionally, patients are offered a violet-colored test-object at its angular size within 25.7-29.0 range and at its correct acceptance deuteranomalia of light degree should be predicted. Additionally, patients are offered a purple-colored test-object at angular size within 30.0-35.7 range and at its correct acceptance protanomalia of the light degree could be predicted. EFFECT: higher efficiency of diagnostics. 3 cl, 1 tbl
