They say eye is the most valuable organ in our body. The man who has lost the sight of his/her eye can only can feel how he/she is missing in the world. There are many treatments in medical science for the people who have lost their eyesight. Recently, some researchers from the Polenov Russian Neurosurgical Institute, Russia, and Institute of Medical Psychology, Germany, developed a new procedure for the treatment of blindness.
The new research and research result shows that non-invasive current stimulation has the ability to induce ‘neuroplastic’ changes in the brain and also improve the visual system structures. This is the main basis of the research.
The researchers treated 446 patients, who were blind because of nerve problem, with non-invasive repetitive transorbital alternating current stimulation (rtACS) for 10 days, which reduced the nerve lesions of the patients. Applying rtACS the visual field (VF) size was improved about 7.1 percent and 9.3 percent in the right and left eye, respectively, according to the result. The research report was published in the journal Brain Stimulation.
The lead researcher of the research Dr. Bernhard Sabel said, “We have shown for the first time that partial blindness can be reduced by a short-lasting therapeutic procedure using non-invasive electrical current stimulation.”
According to the result of the research, the rtACS improves the visual acuity and visual field size effectively. Because of some clinical and psychological requirements, the researchers are still working to get the clear result of the treatment.
