  • Title: [Mechanism of formation of the rheoophthalmogram and electroplethysmogram of the eye].
    Author: Kolinko AI, Zelikson BB.
    Journal: Fiziol Zh SSSR Im I M Sechenova; 1977 Jul; 63(7):970-5. PubMed ID: 892101.
    Abstract:
    In cats, the rheogram of a portion of the vascular tract was recorded during changes of the eye pressure due to brief increase or decrease of the central arterial pressue. Comparison of the recorded changes with the oscillations of electrical conductivity suggest that the latter reflect primarily the changes of the blood linear speed during the time of one pulse cycle (at frequencies over 30 kHz). Slow changes of the electrical conductivity as recorded during electroplethysmography of the vascular tract, reflect primarily the changes of blood volume in the eye tunics.
