Electrical Stimulation for the Treatment of Glaucoma
Evaluate the Safety and Efficacy of Repetitive, Transorbital Alternating Current Stimulation (rtACS) for the Treatment of Glaucoma
Source: ClinicalTrials.gov · Last updated 9 Oct 2026
Brief summary (registry, in English)
The overall aim of this study is to see whether long-term electrical stimulation with a home-stimulation device works well and is safe for the treatment of open-angle glaucoma. Open-Angle Glaucoma is a disease where the nerves in the back of your eye die off faster than expected regardless of your eye pressure.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Participant has any electric or electronic implants such as a pacemaker.
- Participant is currently participating in or has within the last 3 months participated in any other clinical trial of a drug by ocular (if in the study eye) or systemic administration.
- Implanted intracranial magnetic metals (metallic implants in the head / skull such as clamps, coils, ventriculo-peritoneal shunts, endoprostheses, etc.), which are not MRI-compatible. Note: metallic dental implants and titanium screws or plates are acceptable
- Self-reported alcohol or illicit drug addictions within the last 12 months.
- Prior participation in a vision training/stimulation study in the last 12 months
Other illness
- Participant has a history of ocular herpes zoster.
- Participant has uveitis or other ocular inflammatory disease.
- Participant has acute autoimmune disease.
- Participant has, in the opinion of the investigator, any physical or mental condition that would increase the risk of participation in the study or may interfere with the study procedures, evaluations and outcome assessments. Including but not limited to all forms of dementia.
- Patients with history of epileptic seizure within the last 10 years.
- Patients with uncontrolled systemic hypertension or uncontrolled diabetes.
Other
- Participant is unable to comply with study procedures or follow-up visits.
- Participant has pathological nystagmus
- Participant has evidence of visually significant retinopathy including but not limited to Diabetic retinopathy or retinitis pigmentosa.
- Participant has evidence of corneal opacification or lack of optical clarity.
- Participant has acute conjunctivitis.
- Participant is pregnant or lactating.
- Unresected brain tumors
- Patients with any skin damage.
- Children and comatose patients.
- Participant is not able to travel, to comply with the requirements of the study or not willing to complete the schedule of events (SOE) and/or unable to confirm follow-up participation
Who the study is looking for
- Participant must be at least 18.
- Participant must has the ability to comply with the requirements of the study and complete the schedule of events (SOE).
- Participant's clinical diagnosis must be consistent with glaucoma characterized by the following features: Mean deviation (MD) worse than -3 on Humphrey Visual Field 24-2 testing. Reliable visual field measures, fixation losses do not exceed 20% and false positives do not exceed 20%.
- Visual Field Index between 10 and 90%
- Corrected visual acuity ≥ 1.00 (logMAR), 20/200 (Snellen), 0.10 (decimal)
- In the opinion of the investigator the participant's eye pressure must be clinically stable.
- If a participant has two eyes meeting study criteria, the worse eye as determined by mean deviation. If both eyes qualify and have the same MD, the patient may choose which eye they are willing to enter, or else a randomization procedure will assign one eye to the study.
- Participant must understand and sign the informed consent. If the participant's vision is impaired to the point where he/she cannot read the informed consent document, the document will be read to the participant in its entirety.
