Abstract

Aim: To explore the relationship between metabolic risk factors and dry eye syndrome (DES).

Methods: Retrieved studies on the association of metabolic syndrome risk factors (hypertension, hyperglycemia, obesity, and hyperlipidemia) and DES were collected from PubMed, Web of Science, and the Cochrane Library in December 2015. Odds ratio (OR) with 95% confidence interval (CI) were pooled to evaluate the final relationship. Subgroup analyses were conducted according to diagnostic criteria of DES.

Results: Nine cross-sectional studies and three case-control studies were included in this Meta-analysis. The pooled results showed that people with hypertension, hyperglycemia, and hyperlipidemia had a higher risk of suffering from DES (P<0.05), especially the typical DES symptoms. On the other hand, obesity did not increase the risk of DES.

Conclusion: The present Meta-analysis suggests that all metabolic risk factors except obesity were risk factors for DES.

Keywords: Meta-analysis; dry eye syndrome; hyperglycemia; hyperlipidemia; hypertension; obesity.
