RESUMO
The paper gives the comparative results of infrared exposure, drug and multimodality treatment in partial optic nerve atrophy of varying degrees, as evidenced by Doppler, electrophysiological, and morphometric studies.

The paper deals with search for signs or controllers of the adequacy of chosen visual analyzer electrostimulation (ES) parameters accessible for an outpatient physician. The subjective characteristics of phosphene-elementary visual sensation under the influence of electric current on the visual tract are identified; changes in the properties of phosphene in response to those of ES parameters were traced. The subjective characteristics of phosphene indirectly evaluates the degree of visual tract lesion and may serve as a controller of adequacy of ES parameters. The resultant algorithm of management of the properties of each identified characteristics of phoshene significantly enhances the efficiency of therapeutical ES.

Effects of transcutaneous electric stimulation of the eyes on vision acuity, visual field, electric sensitivity, electric lability, Hanzfeld ERG and macular ERG were studied in 260 patients with partial atrophy of the optic nerve of various origins and with different degrees of visual function loss. Dispersion analysis of random samples showed that changes in each characteristic after electric stimulation depended on the initial value of this parameter: in general, the more manifest were deviations from the norm, the more marked was the improvement of this or that function. A conclusion is made on physiological nature of electric stimulation method used for the treatment of optic nerve atrophy.
