METHOD OF TREATMENT OF OPTIC CHANNEL DISEASE BY DIRECT ELECTROSTIMULATION Russian patent published in 1994 - IPC

FIELD: medicine; more particularly, ophthalmology; can be used also in neuro-surgery and neurology. SUBSTANCE: method involves introduction of guide needle accommodating conically tipped stylet through a puncture in the skin with a possibility for further separation of tissues. Then the guide needle is shifted towards the optic nerve without granulation of its membrane but not further then 10 mm from the nerve. After that the stylet is withdrawn and a flexible electrode with a working tip area not less than 10mm² is introduced through the guide needle. The flexible electrode carries hermetically sealed light guide. The guide needle is withdrawn and the outer end of the flexible electrode is secured on the skin surface. Electro- and photostimulation are carried out simultaneously by bidirectional current pulses from 10 to 100 mcA with pulse duration from 1 to 10 ms, and light pulses in the visible light wave range with total energy in the light pulse varying from 10^-2 to 10^-4J . Frequency of repetition of current and light pulses is equal to the pulse rate of the inner carotid artery. Daily session includes 3 to 5 cycles from 50 to 500 pulses in each cycle with 5- to 10-min intervals between cycles. The whole course of treatment includes 10 to 15 sessions. EFFECT: reduced injury, enhanced efficiency of treatment with improved vision function.
