Abstract
INTRODUCTION: Meibomian gland dysfunction (MGD) is the leading cause of dry eye syndrome (DES). Many ocular disorders including DES and blepharitis can be linked to MGD. If we treat MGD, we can treat related diseases easily. PURPOSE: This systematic review is intended to determine the efficacy of omega-3 supplementation in MGD patients. METHODS: This systematic review included an electronic search on PubMed and Clinicaltrials.gov to include all randomized clinical trials (RCTs) using omega-3 as a treatment for MGD. RESULTS: Database search yielded to one RCT and six clinical trials through the MEDLINE of a total of 350 participants for the systematic review and meta-analysis study. The investigated treatment group (omega-3 group) had a positive effect on MGD protection in the invasive sodium fluorescein-tear break up time (NaFl-TBUT) score compared with the placebo group (odd ratio = 8.72, 95% confidence interval: 4.73, 16.09; p < 0.001). These data suggest that the odd ratios of the omega-3 group to control group increased the likelihood of the improved stated outcome tear break up time (TBUT) being achieved in the treatment group. No evidence of publication bias was detected in the funnel plot inspection or the Egger's statistical test (p = 0.2944). CONCLUSIONS: A moderate daily dose of omega-3 may be a beneficial therapeutic for MGD. Omega-3 has been beneficial in many diseases, such as heart attack prevention and agerelated macular degeneration, and this systematic review emphasizes its protection against MGD. In addition, this review emphasizes the precision of noninvasive TBUT (NITBUT) compared with invasive NaFl-TBUT which may suggest the importance of NITBUT in the clinic.
