DIAGNOSTIC TECHNIQUE FOR EYE INJURIES Russian patent published in 2013 - IPC G01N33/52 

FIELD: medicine.

SUBSTANCE: lachrymal fluid is examined by IR spectroscopy to determine the relation of the characteristic peak areas of absorption bands; the derived values are compared to a control reference. Non-penetrating wounds are detected if observing an increase of the peak area relations S₄/S₃ and S₅/S₃ in 2-2.5 times, while the penetrating wounds are shown by an increase of the peak area relations S₄/S₃ and S₅/S₃ in 1.2-1.5 times. S₃ corresponds to a spectral band at wave number 1452 cm^-1, S₄ corresponds to 1548 cm^-1 and S₅ corresponds to 1649 cm^-1.

EFFECT: technique enables specifying a non-penetrating nature of the injury and avoiding a surgical intervention; the technique provides conducting the timely surgical management and determining a therapeutic approach to the patient which makes it possible to reduce the length of hospital treatment and to improve the functional outcome.
