Acupuncture Therapy Is More Effective Than Artificial Tears for Dry Eye Syndrome: Evidence Based on a Meta-Analysis

Abstract EN

Background.

The efficacy of acupuncture in dry eye syndrome patients remains controversial.

Methods.

Pubmed, Ovid, Cochrane libraries, CNKI, Wanfang, and CQVIP databases were electronically searched until October 1, 2014.

Outcomes including tear break-up time (BUT), Schirmer I test (SIT), and cornea fluorescein staining (CFS) were analyzed.

A meta-analysis was performed using both fixed- and random-effects models based on heterogeneity across studies.

Results.

Seven studies were included in this study; 198 and 185 patients were randomly treated with acupuncture and artificial tears, respectively.

The overall BUT of patients in acupuncture group was significantly longer than that of the artificial tears group after treatment ( P < 0.00001 ).

The SIT was significantly higher in the acupuncture group than that in the artificial tears group after treatment ( P = 0.001 ).

The CFS of patients in acupuncture group was significantly improved compared to that in artificial group ( P < 0.0001 ).

Conclusions.

Acupuncture therapy is effective for the dry eye patients, partly better than artificial tear treatment.
