Observational Study to Investigate the Short-term Effects of Transcorneal Electrical Stimulation on Visual Performance

Retinitis pigmentosa and similar degenerative diseases of the retina lead to progressive loss of vision. TES therapy with the CE-marked OkuStim® System is a treatment approved in the EU for slowing the progression of the disease. Patients increasingly report short-term subjective improvements in vision, which have not yet been systematically investigated. This exploratory study is conducted to determine whether these subjective short-term effects can be measured, and therefore also be quantified, by objective tests.
