DEVICE FOR DIAGNOSING VISION SYSTEM PATHOLOGIES IN CHILDREN BASED ON CRITICAL FREQUENCY OF FLICKER FUSION Russian patent published in 2003 - IPC

FIELD: medical engineering. SUBSTANCE: device has casing enclosing means for producing impulses which outputs are connected to two photostimulation units designed as photodiodes fixed in light protection screen mounted on toy car headlight and power supply source unit electrically coupled with the means for producing impulses. The means for producing impulses is designed as microprocessor usable for producing controllable frequency impulses within the limits of 1 to 60 Hz. The device also has transceiver unit operating on infrared radiation mounted inside of the casing and connected to microprocessor and usable for receiving and transmitting data. Indicator unit is connected to the microprocessor for showing critical flicker fusion frequency inherent in the right and left child eye. EFFECT: simplified diagnosis procedure. 5 cl, 3 tbl
