Lacrimal gland duct obstruction and dacryops: Unravelling its pathogenesis with proteomics and cellular profiling

Dacryops involves reactive ductular ectasia and inflammation, resulting in increased MMPs, fibrosis, and loss of the periductal neural network. The cyst fluid is rich in apolipoproteins, immunoglobulins, and complement factors. Future research could focus on the lipidomics of the cyst fluid.
