MacuMira Microcurrent Stimulation for Dark Adaptation in Dry Age-Related Macular Degeneration

30. oktober 2026 opdateret af: Clarity Eye Institute

MacuMira Microcurrent Electrical Stimulation and Dark Adaptation in Dry Age-Related Macular Degeneration

Age-related macular degeneration (AMD) is an eye condition that affects the retina and can lead to progressive vision loss. This study will evaluate the effects of MacuMira microcurrent stimulation on dark adaptation in adults with intermediate dry AMD.

Participants will receive four in-office treatment sessions over 10 to 14 days. Dark adaptation and other measures of visual function and retinal health will be assessed before treatment and at one and three months after treatment.

Eksperimentel: MacuMira Treatment

All participants will receive four in-office sessions of transpalpebral microcurrent electrical stimulation using the MacuMira device over approximately 10 to 14 days.

Four in-office sessions of transpalpebral microcurrent electrical stimulation using the MacuMira device. The first treatment session will occur within 7 days of screening/baseline, with the remaining sessions administered over approximately 10 to 14 days.

Tidsramme
Change in Rod Intercept Time (RIT) from Baseline to Month 1
Tidsramme: Average of two baseline assessments (Screening/Baseline and Treatment Day 1) to the single assessment at Month 1.

Change in RIT, measured using the AdaptDx Pro dark adaptation test, from the average of two baseline assessments to the single RIT assessment at Month 1. The two baseline measurements will be obtained at the Screening/Baseline visit and Treatment Day 1, prior to the first MacuMira treatment, and averaged to establish baseline RIT. Each eligible eye will be assessed separately.

Average of two baseline assessments (Screening/Baseline and Treatment Day 1) to the single assessment at Month 1.
