METHOD OF AGE-SPECIFIC CATARACT DIAGNOSTICS

METHOD OF AGE-SPECIFIC CATARACT DIAGNOSTICS

FIELD: medicine. ^ SUBSTANCE: crystalline lens is laser emitted with wave length within the range 320-350 nm, crystalline lens fluorescence strength is registered by spectrometer in three points at wave length 400, 440, 500 nm. Diagnosis is subject to lenticular opacity index calculated by formula:...

description FIELD: medicine. ^ SUBSTANCE: crystalline lens is laser emitted with wave length within the range 320-350 nm, crystalline lens fluorescence strength is registered by spectrometer in three points at wave length 400, 440, 500 nm. Diagnosis is subject to lenticular opacity index calculated by formula: where alpha is lenticular opacity index, I1 is fluorescence strength at wave length 400 nm, I2 is fluorescence strength at wave length 440 nm, I3 is fluorescence strength at wave length 500 nm, is averaged values of fluorescence strength applicable for transparent crystalline lens at related wave length, is averaged values of fluorescence strength applicable for cataract crystalline lens at related wave length, and value alpha - 0.20-0.40 indicates non-altered crystalline lens behavior, value alpha - 0.41-0.60 indicates phacosclerosis, and values alpha - 0.61-0.80 indicates initial age-specific cataract, value alpha - 0.81-0.90 indicates immature age-specific cataract, and value alpha - 0.91-1.0 indicates mature age-specific cataract. ^ EFFECT: rapid and high accuracy diagnostics of cataract of various developmental stages that in turn enables to start well-timed medicinal treatment and to provide differential approach to treatment of age-specific cataract of various developmental stages. ^ 1 tbl, 2 ex
