METHOD OF PRE-OPERATION PROGNOSTICS OF MACULAR EDEMA FOR DIABETES PATIENTS IN CATARACT MICROSURGERY Russian patent published in 2009 - IPC A61B3/16 A61F9/00 A61B5/02 A61B5/205 A61B3/10 

FIELD: medicine; ophthalmology.

SUBSTANCE: arterial (AP) and intraocular (IOP) pressure is measured twice, at the arrival day and immediately at operating table after operation field processing. Pulse rate (PR) and breath rate (BR) are measured. Stress response value for macular retina (MR) is calculated by the formula: MRSRR=CSI·Δt POP, where MRSRR is macular retina stress response rate for operation trauma; CSI is clinical stressing index calculated by the formula where AP_av1,2 is average arterial pressure equal to AP_diastol+1/3(AP_systol - AP_diastol) at arrival day and before operation, Δt POP is difference of perfusion ocular pressure before operation (POP₂) and at arrival day (POP₁), for MRSRR below 10 areactive macula response to operation stress is predicted, for MRSRR from 10 to 15 hyperreactive respose with reversible subclinical macular retina edema is predicted, for Δt POP equal or over 15 aggressive MR response with development of clinically significant diabetic macular edema.

EFFECT: enhanced pre-operation prognosis accuracy for macular edema development for diabetes patients.
