Why carry out this study?

Dry eye has attracted increasing attention worldwide, in which liver disease was found to be associated with the pathogenesis of dry eye. Currently, more than one-fifth of the population in China has liver disease.

This clinical study evaluated the clinical characteristics of dry eye secondary to different types of liver diseases.

What was learned from the study?

This study found that dry eye secondary to primary biliary cholangitis was more prone to aqueous-deficient dry eye, whereas dry eye secondary to drug-induced liver injury and hepatitis B were more prone to meibomian gland dysfunction.

The types of dry eye secondary to different types of liver disease are not the same, which is important to guide the clinical treatment of liver disease combined with dry eye.
