The disease that causes green crusts in the eyes

Lagañas appear thanks to the segregation of mucous glands of the conjunctiva, goblet cells and Meibomian glands of the eyelids are also aspects that contribute to their appearance. These can form during the night and decrease the production of watery tears, making the secretion thicker.

These can also form during the day while the person’s eyes are open, eliminating this mucous secretion with blinking. When they present an abnormal color, excessive discharge, accompanied by pain and other symptoms, it may be an infection or eye disease.

How are lagañas produced?

The eyes are covered by a 3-layer tear film:

  • Mucous membrane: It directly covers the cornea.
  • Aqueous: Helps spread tears.
  • Fat: Made from the meibum, which is secreted by about 50 glands around the edge of the upper eyelid and another 25 that line the edge of the lower eyelid.
