The aim of the study was the clinical and functional assessment of the complex treatment of glaucomatous optic neuropathy with the administration of the drug tanakan in the form of endonasal electrophoresis in combination with electrical stimulation according to IST and ultrasound Doppler mapping. We examined 43 (74 eyes) patients with GON aged from 58 to 76 years. The results of the study showed that this method effectively delays the development of optic nerve atrophy and, along with the improvement of visual functions, lengthens the positive effect of the main treatment, which was confirmed by a significant improvement in hemodynamic parameters according to the ultrasound Doppler study.
