What is dacryops?

Introduction. Dacryops, also known as lacrimal gland cyst or lacrimal duct cyst, was described more than 200 years ago. It is an uncommon but benign condition characterized by a fluid-filled cyst in association with normal lacrimal tissue.

What causes Dacryops?

Dacryops is thought to be due to prolapse of the lacrimal gland to a sufficient degree to produce obstruction of the lacrimal ducts and chronic inflammation of the lacrimal gland tissue that weakens the wall of the ductules and allows them to expand. Trauma has been implicated in the etiology of dacryops.

In general, a lacrimal gland tumor is rare. Only 1 out of 1 million people are diagnosed with this type of tumor each year. About 55% of epithelial lacrimal gland tumors are benign and 45% are malignant. Malignant epithelial tumors of the lacrimal gland account for 2% of all orbital (eye socket) tumors.
