Objective – to study the electrophysiological figures (phosphen sensitivity barrier and critical flashing frequency disappearance) and effectiveness of electrostimulation of optic nerve in patient with brain tumors of basal localization before and after complex restorative therapy.
Methods and subjects. The condition of visual analyzer in 33 patients with optic nerve atrophy caused by tumor of basal localization was studied. Electrophysiological figures were measured with apparatus КНСО-88 phosphen.
Electrostimulation – with the help of ECO-2.
Results. We established that transcutaneous electrostimulation application promoted improvement of visual
function and visual fields. Electrophysiological figures were also improved – reduction of phosphen sensitivity barrier and increasing the critical flashing frequency disappearing.
Conclusions. The revealed results indicate that in early postoperative period (2–3 weeks) it is effective to use
transcutaneous electrostimulation in patients with partial optic nerve atrophy.
