[A clinical study of thunder-fire moxibustion combined with meibomian gland massage in treatment of meibomian gand dysfunction].

OBJECTIVE

To observe the effect of thunder-fire moxibustion combined with meibomian gland massage in improving meibomian gland dysfunction (MGD) and explore its mechanism.

METHODS

Seventy-two MGD patients with 144 eyes in the Jinhua Hospital of Traditional Chinese Medicine from February 2019 to January 2021 were selected and randomly divided into an experimental group (=36,72 eyes) and a control group (=36, 72 eyes). Patients in the control group received 0.1% fluo-rometholone eye drops and 0.1% sodium hyaluronate eye drops, 1-2 drops per time, four times per day, and the meibomian glands were massaged once per day. Patients in the experimental group received additional thunder-fire moxibustion on the basis of the treatment of the control group, 10 cones per time, once per day. One month after treatment, meibomian gland function was assessed, and the levels of interleukin-6 (IL-6) and prostaglandin E2(PGE2) in tears were detected.

RESULTS

After treatment, the scores of Ocular Surface Disease Index, meibomian hyperemia, meibomian gland opening, meibomian gland loss, and meibomian gland secretion function were lower than those before treatment in the two groups, and the scores of the experimental group were lower than those of the control group (<0.05). After treatment, the tear break-up time and tear meniscus height were higher than those before treatment in the two groups, which were higher in the experimental group than those in the control group (<0.05). The post-treatment levels of IL-6 and PGE2 were lower than those before treatment in the two groups, and the levels in the experimental group were lower than those in the control group (<0.05).

CONCLUSION

Thunder-fire moxibustion combined with meibomian gland massage can significantly improve the function of the meibomian glands and lower the levels of IL-6 and PGE in tears.
