Doctors in Chile have been left stumped after being presented with a patient who apparently cries tears of blood. Yaritza Oliva, a 20-year-old from the city of Purranque, cries blood red tears several times a day after being afflicted by a mysterious condition earlier this month.

After seeking medical assistance, she was prescribed eye drops to ease the burning pain she said was “indescribable.” Her local hospital ruled out both an eye infection and conjunctivitis, believing that she may be suffering from a rare condition known as haemolacria, although it has yet to be officially diagnosed.

Several case of haemolacria have surfaced in recent years, although very little is known about the condition or its causes. (Source)
