Efficacy of Laser Acupuncture on Zanzhu (BL02) as the Treatment for Dry Age-related Macular Degeneration: A Randomized Controlled Trial

This study consists of 15 visits, which are divided into the screening period and the treatment period.

Screening visit After being provided with sufficient information for this study, the patient would voluntarily sign the informed consent. The patients who have submitted the informed consent will undergo screening tests to determine their eligibility. The screening tests include general medical history taking, treatment history for AMD, vision test. Based on the eligibility criteria and screening tests, identification codes would be granted to eligible participants.

Visit 1 Visit 1 will be arranged within a week from the screening visit. The participants who have successfully completed the screening visit can proceed to visit 1 on the same day. The participant's changes in medical history and medication taking since the screening visit will be surveyed. Randomization will be performed on the eligible participants. Before implementing each intervention, examinations would be conducted to measure outcomes, BCVA. The participants would be educated according to the assigned intervention. The experimental group would receive laser acupuncture treatment, and the control group would receive the sham laser acupuncture. In both group, any discomfort or adverse events (AEs) before and after the treatment would be surveyed. Some observation items, including vital signs, vision test, medical history, medication taking, participant's compliance, discomfort before and after the treatment and AEs, will be examined every visit. Participant teaching would also be conducted during every visit.

Visits 2-12 During visits 2-12, the observation items will be examined including visual acuity, medical history, medication taking, discomfort before and after the treatment and AEs since the last visit. Both group would visit three times a week for 4 weeks. At each visit, the experimental group would receive the laser acupuncture treatment, and the control group would receive the sham laser acupuncture. In both group, discomfort before and after the treatment would be surveyed.

Visit 13 Visit 13 will be arranged within 3 days, after a 4-week period has elapsed since visit 1. (If 4 hours have elapsed since the treatment of visit 12, visit 13 could be arranged on the same day as visit 12.) For both group, a survey would be conducted to check any changes related to medical history, medication taking and AEs since visit 12. Vision test will be conducted. When the assessments have finished, treatment satisfaction will be evaluated.
