SUBSTANCE: method involves measuring patient weight, recording age and sex of the patient. The patient is positioned in front of computer display unit. The data are inputted into the computer comprising software containing a program for estimating organism organs and systems condition. The following organs are detected. Lung, spleen, heart, kidneys, liver are proved for having deviations from norm with negative sign towards hypofunction or with positive sign towards hyperfunction. The data are displayed with the program on the screen as a table with reference and current values being shown in relative units with plus or minus sign. Canal states are estimated from detected organs being under maximum stress on the basis of infogram: lung canal P, spleen - canal RP, heart - canal C, kidneys - canal R, liver - canal F. When estimating organ state with deviation having plus sign, that means hyperfunction, canal state is estimated as having energy excess. When organ state deviation has plus sign, that means hyperfunction, canal state is estimated as having lack of energy. Eye diseases are diagnosed from state of organs and canals of P, RP, C, R and F. Hyperfunction in organ and excess in canal being available, initial ophthalmic disease stage is diagnosed. Hypofunction in organ and deficit in canal being available, chronic ophthalmic disease stage is diagnosed.
