Figure 1. Relation of meibomian gland (MG) dropout grades with tear functions, ocular surface disorder, MG acinar unit density and diameters. A-H: The MG drop out grade (severity) showed significant relations with tear functions including BUT, DR-1 tear film lipid layer interferometry grades, TEROS, and fluorescein and Rose-Bengal staining scores (p<0.05) except the mean Schirmer test value (p>0.05; A-F). Both the mean acinar unit density and diameter showed significant relations with MG drop out grades (p<0.05; G-H).
