Microcurrent Stimulation Therapy for Intermediate to Advanced Nonexudative Age-related Macular Degeneration (i-SIGHT2)

May 1, 2026 updated by: i-Lumen Scientific AUS PTY LTD

Microcurrent Stimulation Therapy for Intermediate to Advanced Nonexudative Age-related Macular Degeneration (i-SIGHT2): a Multicentre, Randomised, Sham-controlled, Double-masked, Clinical Device Trial.

The goal of this clinical trial is to characterize the safety and effectiveness of the i-Lumen AMD transpalpebral microcurrent device and therapy in patients with intermediate to advanced nonexudative AMD.

Participants will:

  • Undergo an initial loading regimen, followed by 7 maintenance over the course of 11 months.
  • Participants will return monthly through Month 14 (3 months post-last treatment) for evaluation and monitoring.

  • Older Adult

Accepts Healthy Volunteers

No

Description

Key Inclusion Criteria:

  • Presence of at least one large druse >125 microns in diameter due to AMD.
  • BCVA letter score of 35 to 70 letters (inclusive) (Snellen equivalent 6/12 to 6/60 [20/40 to 20/200])

Key Exclusion Criteria:

  • Any implanted electrical device(s) including deep brain stimulator, hearing or visual implants (i.e., cochlear implant, auditory brainstem implant, retinal prostheses), and/or cardiac defibrillator/pacemaker.
  • Implanted metallic device within 20 cm of the Treatment electrode (study eye(s)) and/or the grounding electrode (base of the hairline on the back of the neck).
  • Uncontrolled diabetes, defined as glycated haemoglobin (HbA1c) >10% (13.3 mmol/L).
