Association of the severity of meibomian gland dysfunction with dyslipidemia in Indian population

Purpose: To correlate the severity of meibomian gland dysfunction (MGD) with the serum lipoprotein levels. Methods: The study was conducted as a prospective observational study over a period of 18 months. Ninety patients diagnosed with MGD were enrolled after they gave their informed consent according to the inclusion-exclusion criteria. Meibomian gland status was evaluated by meibum quality, expressibility, and numerical scoring. Lipid profile was done from an overnight fasting blood sample and evaluated for total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides (TGs). Results: Patients with higher stages of MGD more often had serum TGs >150 mg/dL, total cholesterol >200 mg/dL, an LDL >130 mg/dL, and serum HDL >40 mg/dL, and there exists an association between increasing stage of MGD, and age, female sex, and increasing values of all the lipid profile components. Conclusion: A very strong association exists between increasing age and increasing severity of stage of MGD. A positive association exists between female sex and increasing severity of stage of MGD. A positive association exists between increasing severity of MGD and increasing levels of all the components of lipid profiles, namely LDL, HDL, total cholesterol, and triglycerides.
