Microcurrent Stimulation Therapy for Nonexudative Age-related Macular Degeneration (i-SIGHT) (i-SIGHT)

June 18, 2025 updated by: i-Lumen Scientific, Inc.

Microcurrent Stimulation Therapy for Nonexudative Age-related Macular Degeneration (i-SIGHT): A Multicenter, Randomized, Sham-controlled, Feasibility Device Trial.

Evaluate the safety and efficacy of transpalpebral microcurrent stimulation (MCS) therapy for patients with nonexudative (dry) age-related macular degeneration (AMD).

Detailed Description

The i-Lumen(TM) AMD device is for in-office therapy use to deliver microcurrent electrical stimulation transpalpebrally (via the eyelid) for use by an ophthalmologist. The i-Lumen AMD device contains proprietary software with preset treatment algorithms and is calibrated at each session to the individual participant.

Up to 30 enrolled participants will be randomized (2:1 active to sham ratio) and complete the initial 5-day loading treatment sessions. Participants completing the initial loading sessions will receive two (2) days of maintenance treatments and be following and be followed through the one (1) year time point.
