Electrical Stimulation for the Treatment of Glaucoma
Recruiting
Trial ID: NCT05626491
Purpose
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.
Official Title

Eligibility
Inclusion Criteria:
1. Participant must be at least 18.
2. Participant must has the ability to comply with the requirements of the study and
complete the schedule of events (SOE).
3. 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%.
4. Visual Field Index between 10 and 90%
5. Corrected visual acuity ≥ 1.00 (logMAR), 20/200 (Snellen), 0.10 (decimal)
6. In the opinion of the investigator the participant's eye pressure must be clinically
stable.
7. 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.
8. 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.
Exclusion Criteria:
1. Participant is unable to comply with study procedures or follow-up visits.
2. Participant has a history of ocular herpes zoster.
3. Participant has pathological nystagmus
4. Participant has evidence of visually significant retinopathy including but not limited
to Diabetic retinopathy or retinitis pigmentosa.
5. Participant has evidence of corneal opacification or lack of optical clarity.
6. Participant has uveitis or other ocular inflammatory disease.
7. Participant has any electric or electronic implants such as a pacemaker.
8. Participant has acute conjunctivitis.
9. Participant has acute autoimmune disease.
10. 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.
11. Participant is pregnant or lactating.
12. 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.
13. Unresected brain tumors
14. 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
15. Patients with any skin damage.
16. Children and comatose patients.
17. Patients with history of epileptic seizure within the last 10 years.
18. Patients with uncontrolled systemic hypertension or uncontrolled diabetes.
19. Self-reported alcohol or illicit drug addictions within the last 12 months.
20. 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
21. Prior participation in a vision training/stimulation study in the last 12 months
