摘要
FIELD: medicine, ophthalmology, diagnostics. SUBSTANCE: method deals with preliminary diagnostic electroimpact with a biphase rectangular impulses for the necessary areas due to multichannel electrode applied onto orbital region. According to diagnostic results curative electroimpact is conducted by series of impulse batches at optimal parameters determined for each necessary area. Duration of curative electroimpact impulses corresponds to minimal threshold of electrophosphene initiation in a patient, impulse amplitude corresponds to minimal threshold of interrupted electrophosphene initiation at minimal frequency. Curative electroimpact is performed beginning from the most functionally saved areas. Multichannel stimulator contains a block of regime choosing, a block of parameter input, formers of impulses for cycles, series, seances, a counter of impulse quantity, a transformer of signal level, a channel switcher, a generator of tempo impulses, a generator of current, a regulator of amplitude and analog key. Additionally device is supplied with a control block, a block of parameter saving, a block of indication, a former for channel switching. EFFECT: higher efficiency. 3 cl, 5 dwg
