Impact of Dyslipidemia on Tear Film and Meibomian Gland Dysfunction: A Cross-Sectional Study of the Interplay between Serum Lipid Profile and Ocular Surface Health

Figure 2

LLTF patterns in patients according to their HDL levels: (A) LLTF pattern (grade 2) for a patient with low HDL levels (<40 mg/dl) and (B) LLTF pattern (grade 1) for a patient with high HDL levels (>40 mg/dl). LLTF: lipid layer tear film and HDL: high-density lipoprotein.
