Haemolacria

Haemolacria or hemolacria is a physical condition that causes a person to produce tears that are partially composed of blood.
Description
Haemolacria can manifest as tears ranging from merely red-tinged to appearing to be entirely made of blood, 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.
Cases
From Lucknow, India, Dwivedi presented a rare condition that appeared to cause her to spontaneously bleed from her eyes and other parts of her body without presenting any visible wounds. Dwivedi was the subject of numerous medical research studies and TV shows including Body Shock and a National Geographic documentary.
In the absence of a medical explanation for her condition, some religious explanations have been posed. It was suggested that she could have had an unknown disease, but more skeptical views hypothesized that the case might be explained by Münchausen syndrome by proxy, where her mother, seemingly the only one to witness her bleeding actually starting, was fabricating the story and somehow inducing the effect on the girl. Sanal Edamaruku observed in 2010 that the pattern seemed to match her menstrual cycle and believed that she was faking the symptoms.

In popular culture
French author Marquis De Sade claimed to have "wept tears of blood" after he thought his novel The 120 Days of Sodom was thought to be lost in July 1789. However, the work was later recovered. It is unclear if De Sade actually suffered haemolacria, or if he was just using it as a figure of speech.
