DIFFERENTIAL DIAGNOSIS METHOD FOR DETECTING OPTIC NERVE STAGNATION DISK AND ANTERIOR ISCHEMIC NEUROPATHY Russian patent published in 2006 - IPC A61B3/06 

FIELD: medicine.

SUBSTANCE: method involves obtaining optic nerve disk image by means of fundus camera. Primary color components parameters are determined. Color distribution diagrams are built in eye fundus image in 256 color gradations for a patient under study. Red color bandwidth, blue color minimum, green color median and green color mode. The built primary color distribution diagrams are compared to reference diagrams using maximum likelihood test. Red color bandwidth being from 58 to 79, blue color minimum from 77 to 148, optic nerve stagnation disk is to be diagnosed. Red color bandwidth being from 15 to 58, blue color minimum from 0 to 16, green color median from 163 to 175, green color mode from 148 to 184, anterior ischemic neuropathy is to be diagnosed.

EFFECT: high reliability of diagnosis.
