What is "haemolacria"

n. (context pathology English) The shedding of tears containing blood

Haemolacria is a physical condition that causes a person to produce tears that are partially composed of blood. It can manifest as tears that are anything from merely red-tinged to appearing to be entirely made of blood.

Haemolacria is a symptom of a number of diseases, and may also be indicative of a tumor in the lacrimal apparatus. It is most often provoked by local factors such as bacterial conjunctivitis, environmental damage or injuries.

Acute haemolacria can occur in fertile women and seems to be induced by hormones, similarly to what happens in endometriosis.
