Associations between the grade of meibomian gland dysfunction and dyslipidemia

To examine the relationship between dyslipidemia and the severity of meibomian gland dysfunction (MGD).

A prospective cohort study of 132 subjects with and 104 without MGD were recruited. A correlation between serum fasting lipids and MGD severity was performed.

Mean age for all candidates was 49.4 years; and 57% were women. In all, 42.9% had no MGD, 14.8% had grade 1 MGD, 17.4% had grade 2 MGD, and 23.7% had grade 3 MGD. High cholesterol was found in 37.1% of grade 1 MGD, 43.9% of grade 2 MGD, and 50% of grade 3 MGD. High triglyceride was found in 5.7% of grade 1, 14.6% of grade 2, and 39.3% of grade 3 patients. High low-density lipoprotein was found in 17.1% of grade 1, 29.3% of grade 2, and 35.7% of grade 3 patients. The mean age of the control group was 41.2 years; and 55.4% were women. High cholesterol was found in 42.3%, triglyceride in 7.7%, low-density lipoprotein in 23.1%, low high-density lipoprotein in 3.8%, and high high-density lipoprotein in 3.8%.

Although the presence of MGD does not have any correlation with dyslipidemia, the prevalence of high triglyceride and low-density lipoprotein levels increases with the increasing severity of MGD. This might highlight the significance of monitoring fasting serum lipids due to its association with the potential correlation with the progression of MGD.
