METHOD FOR PREDICTING DIABETIC RETINOPATHY Russian patent published in 2007 - IPC G01N33/92 G01N33/84 G01N33/68 

FIELD: medicine, ophthalmology.

SUBSTANCE: due to biochemical testing lacrimal fluid (LF0 it is necessary to detect the concentration of cholesterol, activity of superoxide dismutase (SOD) and catalase, in blood one should detect the concentration of nitrites and based upon the values obtained calculate Function 1 and Function 2. Function 1 = -3.4+0.29(NO₂)+32.5(cholesterol)-0.97(catalase)-17.28(SOD) - corresponds to Y-axis values and Function 2 = -7.14+0.17(NO₂)+37.2(cholesterol)+2.1(catalase)-17.28(SOD) - corresponds to X-axis values on the scheme to detect lesion type. If the point obtained is on the field of the 1^st scheme one should detect the presence of nonproliferative DR form in a patient at no risk of proliferation; if it is on the field of the 2^nd scheme - nonproliferative DR form with the risk of proliferation; if it is on the field of the 3d scheme - proliferative form of retinopathy in the phase of neovascularization. Application of the present method enables to carry out diagnostics in due time, differentiation in doubtful cases directed towards adequate treatment and decreasing the risk for DR progressing.

EFFECT: higher accuracy of diagnostics.
