Answer

This is caused by the obstruction of drainage of the mucous layer of the tear film with collection of debris and denuded epithelial cells from the surface of the eye.

Frequently, it may be associated with conjunctivitis. This is attributed to the toxic nature of the debris to the surface of the eye or because of exotoxins produced by staphylococcal organisms, which normally reside on the external surface of the eye and are not cleared by the normal tear outflow.
