Abstract:Objective: Observing the clinical efficacy of ocular acupuncture in the treatment of dry eye due to the deficiency of Qi and Yin, and to explore its mechanism. Methods: In this prospective study, 74 patients with dry eye due to the deficiency of Qi and Yin from the Second Affiliated Hospital of Liaoning University of TCM were recruited from January to April 2021. Seventy-four patients were randomly divided into an ocular acupuncture group and a conventional acupuncture group, 37 patients in each group. The conventional acupuncture group was treated with conventional acupuncture; the ocular acupuncture therapy group received ocular acupuncture therapy, and 4 acupoints were taken from the liver, lung, spleen and kidney regions. The course of treatment was 14 days. The ocular surface disease index (OSDI) score before and after treatment was recorded. The Schirmer Ⅰ test (SⅠT) and corneal fluorescein staining (CFS) were used for assessment. The non-invasive first tear film break-up (NIBUTf) and non-invasive average tear film break-up (NIBUTav)were measured by the K5M ocular surface analyzer. Data were analyzed by the t test, Wilcoxon test and Chi-square test. Results: The OSDI score, S Ⅰ T, NIBUTf, NIBUTav and CFS of the two groups were significantly different before and after treatment (P<0.05). After treatment, the OSDI score, S Ⅰ T, NIBUTf, and NIBUTav of the two groups were significantly different (P<0.05). There was no significant difference in CFS between the two groups after treatment. Conclusion: Both ocular acupuncture and conventional acupuncture can effectively treat dry eye due to the deficiency of Qi and Yin. Ocular acupuncture is superior to conventional acupuncture in improving ocular surface symptoms, tear secretion and tear film rupture time of dry eye patients, with a higher efficacy and compliance.
