Effect of acupuncture on dry eye and tear inflammatory factors
Objective On the basis of sodium hyaluronate eye drops
to observe the clinical efficacy of acupuncture on dry eye and explore the effect mechanism of ocular surface protection. Methods A total of 80 patients with dry eye were randomly divided into an observation group and a control group
40 cases in each group. The control group was treated with routine cleaning of eyelid margin
hot compress of eyes with warm towel
and external application of sodium hyaluronate eye drops for 5 weeks. On the basis of the treatment as the control group
the observation group was treated with acupuncture at Jingming(BL 1)
Cuanzhu(BL 2)
Chengqi(ST 1)
Hegu(LI 4)
Zusanli(ST 36)
Sanyinjiao(SP 6)
etc.
once a day
6 times a week for 5 weeks(30 times totally). Before and after treatment
SchirmerⅠtest(SⅠT)
breaking up time(BUT)
corneal fluorescent(FL) score
ocular surface disease index(OSDI) score
and the contents of IL-6 and TNF-αin tears were evaluated and the therapeutic effect was compared between the two groups. Results Compared with before treatment
SⅠT and BUT after treatment in the observation group were prolonged(P<0.05)
the scores of FL and OSDI and the contents of IL-6 and TNF-α in tears were decreased(P<0.05). After treatment
SⅠT and BUT in the observation group were longer than the control group(P<0.05)
and the scores of FL and OSDI and the contents of IL-6 and TNF-α in tears in the observation group were lower than the control group(P<0.05). The total effective rate in the observation group was 87.5%(35/40)
which was higher than 45.0%(18/40) in the control group(P<0.05).Conclusion On the basis of sodium hyaluronate eye drops
acupuncture could improve the clinical symptoms of dry eye
promote the secretion of tears
prolong the tear film breaking up time
and reduce corneal damage
and effect mechanism may be related to the reduction of inflammatory response.
