Brief Summary:
To determine if electroacupuncture acts as an dry eye treatment rather than a placebo, and identify if benefits are linked to corneal subbasal nerve changes and neuroimmunomodulatory indicators.
Detailed Description:
Acupuncture is an important method in the treatment of diseases in Chinese medicine and plays an important role in the treatment of many diseases. Electroacupuncture (EA), as a combination of acupuncture and electric stimulation, is now widely used in research and clinical treatment. Our preliminary study found that compared with 0.1% sodium hyaluronate eye drops, EA exerted more beneficial and durable effects after four weeks of treatment. However, the placebo effect of EA cannot be ruled out yet. The aim of this study is to determine if EA acts as an dry eye treatment rather than a placebo, and identify if benefits are linked to corneal subbasal nerve changes.
This is a multicenter, randomized, subject-blinded, sham-controlled trial. A total of 168 participants with mild-to-moderate dry eye will be randomly assigned (1:1) to verum EA or non-penetrating non-acupoint sham EA (3 times weekly for 4 weeks), followed by a 24-week follow-up. The primary efficacy outcome is the change from baseline to week 4 in the Noninvasive Tear Breakup Time (NIBUT). Secondary efficacy outcomes include tear meniscus height (TMH), Schirmer I test (SⅠT), corneal topography, corneal and conjunctival sensation, scores of Ocular Surface Disease Index (OSDI), corneal fluorescein staining (CFS), Numerical rating scale (NRS), and Chinese Dry Eye Related Quality of Life Scale (CDERQOL) . Additionally, we will apply the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder (GAD-7) to understand the mental health conditions of patients. IVCM will be performed to observe the morphological changes of the corneal basal nerve. The changes of NGF, CGRP, NPY, 8-OHDG, 4-HNE, MDA and other neuroimmunomodulatory indicators in tears and conjunctival cells will be detected by immunofluorescence, ELISA, or other techniques.
