METHOD OF MALFUNCTION ESTIMATION OF VISUAL SYSTEM BRIGHTNESS-CONTRAST CANALS

METHOD OF MALFUNCTION ESTIMATION OF VISUAL SYSTEM BRIGHTNESS-CONTRAST CANALS

FIELD: ophthalmology. SUBSTANCE: measurement of increment (at increasing contrast stimulus) and decrement (at decreasing contrast stimulus) thresholds of brightness-contrast sensitivity is performed at different points of visual field. If change of interval increment and decrement thresholds is beyo...

Zusammenfassung:FIELD: ophthalmology. SUBSTANCE: measurement of increment (at increasing contrast stimulus) and decrement (at decreasing contrast stimulus) thresholds of brightness-contrast sensitivity is performed at different points of visual field. If change of interval increment and decrement thresholds is beyond range of normal age values, malfunction of visual system contrast canals is diagnosed. EFFECT: enhanced accuracy of estimation. 2 exp
