[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.

[The results of direct electrostimulation of the involved optic nerves in neurosurgical patients].

The article generalizes experience in the restoration of vision by direct stimulation of damaged optic nerves after operations for pathological conditions of the chiasmal-sellar region (tumors of the chiasmal-sellar region, optochiasmic arachnoiditis, damage of the optic nerve in the bone canal) in 111 patients. The therapeutic effect was favourable in two thirds of the patients. Indications are determined for the use of the method in various types, duration, and severity of the disease. The use of the method with due regard for the determined indications increases the reliability, degree, and rate of restoration of vision in patients who underwent operation.

[Preliminary results of direct stimulation of damaged optic nerves].

The authors approbated in the clinic a new method for restoring vision in 22 patients in damage of the optic nerves caused by pathological processes in the opticochiasmic area of the brain (tumors of the hypophysis, arachnoiditis, the sequelae of trauma). The novelty of the method lies in introducing electrodes under the nerve sheath during operation performed for the main pathological process and producing direct electrostimulation (ES) of the nerves for 3-4 weeks after the operation. The authors chose the optimum parameters of therapeutic ES under control of a direct record of the bioelectrical activity of the optic nerves and ophthalmological examination of the patients. Positive therapeutic effect was obvious in three fourths of patients, in one third of whom vision was completely normalized. The results of using the new method of implantation of electrodes into the optic nerves and the probable mechanisms of the restoration of vision under the effect of their direct ES are discussed.
