Many patients with nystagmus (involuntary eye movements) suffer from blurred vision, unstable visual perception and decreased visual acuity (VA), which leads to a decreased quality of life. The etiologies of DBN are diverse.
This study provides proof of concept that non-invasive real-time computer-based visual feedback compensates for the SPV (slow phase velocity) in DBN. Therefore, real-time visual feedback may be a promising aid for patients suffering from oscillopsia and impaired text reading on screen.
