study of application of transcutaneous pulsed electrical stimulation around eye in age-related macular degeneration

Conditions: Early to Moderate Dry Age-Related Macular Degeneration

Summary: this study aims to evaluate the safety and efficacy of applying pulse electrical stimulation around eyes of age-related macular patients.

duration of study period(per participant): screening period(0-4weeks), intervention period(16weeks) patient needs to visit site at least 5 times(screening, v2, v3, v4, v5). v2 can be done with screening visit. visit 3, 4, 5 is 2weeks, 6weeks, and 16weeks after visit 2(baseline).
