Haemolacria or hemolacria is a physical condition that causes a person to produce tears that are partially composed of blood.
Haemolacria can manifest as tears ranging from merely red-tinged to appearing to be entirely made of blood,[1] and may also be indicative of a tumor in the lacrimal apparatus.
[2] On rare occasions, a nosebleed may result in bloody tears if the shed blood is forced to flow up and through the nasolacrimal ducts.
On the television series Manifest, Dr. Saanvi Bahl suffered from hemolacria and erratic blood pressure in the season 3 episode Bogey.
Protein analysis of paper letters written by Vlad Dracula has revealed evidence suggesting haemolacria, consistent with stories from the last years of his life.
