简要总结
The purpose of this study is to expand the safety assessment of repeated applications of an electrical current from a DTL-like electrode in patients with RP.
详细描述
This is a single-arm open label interventional safety trial with RP patients, who receive weekly TES for 6 months on 1 eye followed by observation for another 6 months without stimulation. The primary outcome measure is safety, indicated by the frequency and severity of adverse events.

入选标准
- •patients with retinitis pigmentosa (rod-cone dystrophy) after prescription of electrical stimulation by an ophthalmologist
- •adult patients who are capable of giving consent,
- •Visual acuity ≥ 0.02
- •because the electrode is to be positioned on the eye at home, the patient or his family members should have sufficient fine motor skills (assessment by the study physician)
- •the patient must be capable of giving consent and a medical assessment that he/she is able to participate in the whole study according to the protocol
排除标准
- •diabetic retinopathy
- •neovascularisation of any origin
- •after arterial or venous occlusion
- •after retinal detachment
- •silicone oil tamponade
- •dry or exudative age-related macular degeneration
- •macular edema
- •all forms of glaucoma
- •any form of corneal degeneration that reduces visual acuity
- •systemic diseases that are difficult to control or manage, that could endanger the normal study schedule
- •patients in a permanently poor general condition, which could hinder the regular attendance at control examinations in the clinic
- •forms of mental illness related to the bipolar affective and schizoid-affective disorders, and all forms of dementia
- •simultaneous participation in another interventional study or history of interventions whose effect may still persist
