Meibum Lipid Composition and Conformation in Parkinsonism.

Purpose: Patients with Parkinson's disease (PD) exhibit unstable tear films. Tear film lipid composition and structure are related to tear film stability and dry eye and tear lipids have not been characterized in people with PD. The aim of this study is to characterize Meibum tear lipids in donors with PD using H-NMR and infrared spectroscopy.
