Statement of the Problem: Macular degeneration (MD) is the leading cause of irreversible vision loss in people over
50. Without effective treatment, those with some signs of MD will increase upto 70% by 2030. Currently, there is no
treatment for dry macular degeneration.
Purpose: The purpose of this case series is to demonstrate that transpalpebral NI-ES, is beneficial in treating dry
MD.
Methodology & Results: Twelve patients were randomly divided into two groups. In the treatment group, 6 patients
underwent one treatment session of ten minutes to both the eyes daily for three consecutive days with an active eye
stim device. The second group of 6 patients acted as the control group. This group underwent one sham treatment
session for 10 minutes with a non-functional eye stim device treating both eyes daily for three consecutive days
during week 1. Followed by one active treatment session for three consecutive days with an active eye stim device
during week 2. At the end of 3 days, the eyes treated with the eye stim in the treatment group improved on average
3.9 lines (or 19 ETDRS letters). The control eyes lost on an average about 1 line (6 ETDRS letters).
Conclusion & Significance: This case report demonstrates that NI-ES is beneficial for those with dry MD. It is
non-invasive and was well tolerated in each case with no one reporting any side effects. The positive effect on VA
occurred quickly, after 1 ten minute session, and continued to improve after 3 days of treatment. The changes
observed indicate the potential efficacy of microcurrent electrical stimulation to improve vision, slow progression,
and possibly stabilize dry MD. Based on the very promising results, studying a larger group of patients is needed and
gives hope of a new therapeutic option.
