Current Stimulation of the Brain Restores Vision in Patients with Glaucoma and Optic Nerve Damage

Randomized, clinical trial shows that modulating brain plasticity offers a promising avenue for vision restoration and rehabilitation 

When patients who have been diagnosed with optic nerve damage or glaucoma begin to experience vision loss, it is generally considered to be irreversible. However, researchers in this study believe they have found away to restore some of the vision loss based on transorbital alternating current stimulation (ACS). “ACS treatment is a safe and effective means to partially restore vision after optic nerve damage probably by modulating brain plasticity, re-synchronizing brain networks, which were desynchronized by vision loss. This class 1 evidence is the first ever large-scale, multi-center clinical trial in the field of non-invasive brain modulation using electric currents and suggests that visual fields can be improved in a clinically meaningful way,” commented lead investigator Bernhard A. Sabel, PhD, of the Institute of Medical Psychology, Medical Faculty, Otto-von-Guericke University of Magdeburg (Germany). To read more, click here.
