This pilot randomized controlled trial aims to evaluate the efficacy and safety of FSN in improving symptoms in patients with dAMD.38 eligible participants will be recruited and randomly assign them in a 1:1 ratio to the FSN group and the control group. Throughout the study, both groups will take oral vitamin C and vitamin E supplements for a total of 28 days. Participants in the FSN group will receive four treatment sessions over two weeks. Both groups will be assessed at the end of the FSN treating period during the mid-study period, with ocular blood flow dynamics measured using OCTA, followed by a two-week follow-up. The primary outcome of this trial is the change in visual acuity from baseline to week 2, with secondary outcomes including visual field, visual function scale, macular thickness, central avascular zone area vascular density, and choroidal thickness.

Inclusion Criteria:

（ 1 ） Age between 50 and 85 years old with no gender restrictions （ 2 ） Meets the diagnostic criteria for dry age-related macular degeneration (AMD) as outlined in the 2023 Chinese Clinical Practice Guidelines for Age-Related Macular Degeneration （ 3 ） Both monocular and binocular cases of dry AMD are included. For patients with bilateral lesions the experimental group is based on the patient's preferred eye (if both eyes are preferred the average of the data collected from both eyes is included in the analysis) （ 4 ） Participants must voluntarily consent and sign an informed consent form and be willing to cooperate with follow-up visits.

Exclusion Criteria:
