Laser Acupuncture on Dry Eye and Sjögren's Syndrome-related Dry Eye Symptoms (LADESJS)

Recruiting now · Phase 2 · Has a placebo group

Conditions studied: Dry Eye Syndrome (DES), Laser Acupuncture, Sjögren's Syndrome (SS)

In brief

This randomized, double-blind, placebo-controlled clinical trial aims to evaluate the efficacy of adding laser acupuncture at Fengchi (GB20), Zanzhu (BL2), Hegu (LI4), and Quchi (LI11) acupoints to standard care for the treatment of dry eye symptoms in both Sjögren's Syndrome-related dry eye (SJS-DES) and non-Sjögren's Syndrome-related dry eye (Non-SJS-DES) populations. A total of 140 dry eye patients will be recruited and divided into two groups: 70 participants with SJS-DES and 70 with Non-SJS-DES. Participants will be randomly assigned into three groups: Sham+LA group (60 participants receiving 4 weeks of placebo laser acupuncture followed by 4 weeks of active laser acupuncture), LA+LA group (60 participants receiving 4 weeks of active laser acupuncture followed by another 4 weeks of active laser acupuncture), and a Waiting List group (20 participants receiving no laser acupuncture treatment). Each session will target the Fengchi (GB20), Zanzhu (BL2), Hegu (LI4), and Quchi (LI11) acupoints bilaterally, performed twice a week. The total study period is 8 weeks, and the treatment efficacy will be assessed at the end of the 8-week treatment. The Waiting List group (20 participants) will not receive any laser acupuncture treatment during this period. Efficacy will be evaluated using the Numerical Rating Scale (NRS), Schirmer's test, Ocular Surface Disease Index (OSDI), EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI), Traditional Chinese Medicine (TCM) tongue diagnosis, TCM pulse diagnosis, TCM constitution questionnaire, TCM heart rate variability analysis, nailfold microcirculation assessment, and iris examination. This study aims to investigate the impact of laser acupuncture on dry eye symptom improvement and the potential markers that differentiate between SJS-DES and Non-SJS-DES patients. The goal is to develop a comprehensive integrated care model for early screening, diagnosis, and personalized treatment plans for Dry Eye Syndrome and Sjögren's Syndrome, achieving the ultimate objective of "Holistic Health Care."
