Description of therapy

Vision restoration therapy (VRT) is a computer-based treatment which claims to help with visual field defects regain visual functions through repetitive light stimulation. As the device used in VRT is similar to the DynaVision 2000 that already exist the

Emerging Research

A recent study from the University of Colorado Anschutz Medical Campus has introduced **LL-341070**, a potential drug that may aid in vision restoration for individuals with neurodegenerative diseases such as

(MS). The drug enhances the repair of **myelin**, the protective sheath around nerve fibers, which is critical for proper nerve function. In preclinical trials on mice, the drug demonstrated significant improvements in vision-related brain functions by accelerating myelin repair. Researchers believe this therapy could complement existing vision restoration techniques in the future.
