Repetitive Transcranial Alternating Current Stimulation (rtACS) for the Treatment of Optic Neuropathies

Inclusion Criteria11

• Participant must be at least 18.
• Clinical diagnosis of glaucoma, with Humphrey Visual Field 24-2 mean deviation (MD) between -22 dB and -5 dB, and Visual Field Index (VFI) between 10% and 90%. The visual field test at screening must meet the following reliability indices:
• Fixation losses (FL) ≤ 33%
• False-negative rate (FNR) ≤ 20%
• False-positive rate (FPR) ≤ 20% At initial screening, the difference in MD between two consecutive visual field tests must be less than 2 dB.
• Best-corrected visual acuity (BCVA) ≥ 0.2 in the worse eye selected for stimulation treatment.
• If a participant has two eyes meeting study criteria, one eye will be randomly selected by computer for study participation.
• In the opinion of the investigator the participant's eye pressure must be clinically stable.
• Participant must has the ability to comply with the requirements of the study and complete the schedule of events.
• 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.
• Optical coherence tomography (OCT) imaging shows measurable changes in either peripapillary retinal nerve fiber layer (RNFL) thickness or macular ganglion cell-inner plexiform layer thickness.
