RT Journal Article SR Electronic T1 Rare case of red tears: ocular vicarious menstruation JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e237294 DO 10.1136/bcr-2020-237294 VO 14 IS 3 A1 Soumitra Ghosh A1 Sudheer Tale A1 Neha Handa A1 Ashish Bhalla YR 2021 UL http://casereports.bmj.com/content/14/3/e237294.abstract AB Bloody tears or haemolacria is a rare clinical entity. It is caused by various ocular and systemic conditions. Haemolacria due to vicarious menstruation is even rarer. In this article, we presented a case of cyclical episodes of bloody tears coinciding with menstrual cycle in a 25-year-old married female patient. Extensive physical, ophthalmological and radiological evaluation failed to reveal other potential causes of her complaint. A diagnosis of ocular vicarious menstruation was made and she was treated with oral contraceptive pills. No such episode recurred during 3 months follow-up period.
