More Details: Abstract Meibomian gland dysfunction is a chronic ocular surface disease with a complex pathogenesis, whose main clinical manifestations are meibomian gland obstruction or/and lipid abnormalities. To explore the mechanism of MGD due to meibomian gland obstruction (MGO), we established a rat model of MGO by cauterizing the meibomian gland orifice. The morphology of the lid margins and meibomian gland orifices were visualized by slit lamp. The tear production of rats was measured by phenol red cotton thread, the tear film breakup time and corneal fluorescein staining scores of rats were detected under cobalt blue light of slit lamp. Changes in the histological structure of the meibomian gland (MG) were observed by HE staining, Oil Red O staining and immunofluorescence staining (collagen IV). RNA sequencing was used to detect differentially expressed genes in MGO and normal rats, which were validated by qPCR. In the MGO group after 4, 8, and 16 weeks, the meibomian gland orifices were closed, tear film break-up time decreased and corneal fluorescein staining score increased (p
