[The results of using therapeutic periorbital electrostimulations in neurology patients with partial atrophy of the optic nerves].

Results of clinical application of method of non-contact periorbital electrostimulation in 6 groups of neurologic patients (total number-246) with optic nerve pathology of different origin (post-traumatic, hypertensive, inflammatory) are summarized. Analysis of interdependence between positive results and severity of visual disorders, type of the disease, responsible for partial atrophy of optic nerve, was performed. This method of restoration of vision in investigated patients proved to be effective both in hospitals and outpatient departments.

Clinical and physiological basis for a new method underlying rehabilitation of the damaged visual nerve function by direct electric stimulation.

A new method of rehabilitation of damaged visual nerves has been tested during clinical physiological investigations in 45 patients with pathological opticochiasmal brain tumor, inflammation and trauma. The essence of the new method was in implanting the electrode into the nerve when the patient was operated on for the pathological formation and in directly stimulating the nerves for 2 or 3 postoperational weeks. Effectiveness of electrical stimulation was increased by direct recording of the electroneurogram as well as by the results of ophthalmological observations. Considerable improvement of vision was observed in 75%, and in 25% of these cases the vision was found to actually normalize. Even in cases of total blindness, vision was partially rehabilitated in 8 of 10 cases. Direct electrophysiological investigation of the visual nerve potentials enabled us to objectively estimate their functional state, predict the probability of visual rehabilitation as well as increase the efficiency of therapy. Neurophysiological mechanisms of visual rehabilitation under the influence of electrical stimulation of the visual nerves are discussed.

[The dynamics of the superslow potential fluctuations in the decaminute range after intracranial operations].

It is shown that the dynamics of superslow fluctuations of potential (SSFP) in healthy individuals are similar to those in patients before the operation. In a favourable postoperative period SSFP lability is highest during the first week, particularly in the head quadrant adjacent to the zone of the operative wound. Subsequently the SSFP values came closer to the preoperative, i.e. corresponded to the characteristics of this type of brain activity in a healthy person.

[Indications for the use of a method of direct electrostimulation of the optic nerves in patients with pathology of the chiasmal-cell region].

The authors generalize the results of the use of the method of direct electrostimulation of optic nerves in 145 patients with pathology of chiasmal-cellar region (tumours, optochiasmal arachnoiditis, severe craniocerebral traumas with injuries of the bony optical canal) after the operations. The efficacy of the method was shown in 2/3 of observations with retention of residual visual functions. Differences in the efficacy of treatment of patients with various nosological forms of the disease have been revealed; indications for the use of the new method have been defined.
