[Thumb-tack needle based on theory for dry eye: a randomized controlled trial].

Objective: To compare the clinical efficacy of thumb-tack needle and sodium hyaluronate eye drops for dry eye.

Methods: A total of 60 patients with dry eye were randomly divided into a thumb-tack needle group and a western medication group, 30 cases in each group. Based on theory, thumb-tack needle was applied at Zhiyin (BL 67), Lidui (ST 45), Fuyang (BL 59), Yanglao (SI 6), Jingming (BL 1) and Cuanzhu (BL 2) in the thumb-tack needle group, 2 times a week. In the western medication group, 0.1% sodium hyaluronate eye drops were applied, 3 times a day. Both groups were treated for 4 weeks. Before and after treatment, TCM symptom score, tear film break-up time (BUT), SchirmerⅠtest (SⅠT), corneal fluorescein sodium staining (FL) score and 36-item short form health survey (SF-36) score were observed, and the clinical efficacy was evaluated in the two groups.

Results: After treatment, the total scores and each item score of TCM symptom in the two groups were decreased compared with before treatment (<0.05); except for score of visual fatigue and photophobia, the total score and each item score of TCM symptom in the thumb-tack needle group were lower than the western medication group (<0.05). After treatment, the BUT, SⅠT and SF-36 scores were increased and the FL scores were decreased in the two groups (<0.05); the BUT, SⅠT and SF-36 score were higher than the western medication group (<0.05), and the FL score was lower than the western medication group (<0.05) in the thumb-tack needle group. The total effective rate in the thumb-tack needle group was 93.3% (28/30), which was higher than 80.0% (24/30) in the western medication group (<0.05).

Conclusion: Thumb-tack needle based on theory could effectively relieve clinical symptoms of dry eye patients, prolong tear film break-up time, increase tear secretion, improve tear film function and quality of life, and its curative effect is better than sodium hyaluronate eye drops.
