Term Detail
MP term:excessive tearing
Synonym: epiphora
Synonym: lacrimous eye
MP id: MP:0001349
Definition: an unusually high amount of fluid in the eye, either oversecreted by the lacrimal glands, or due to imperfect drainage by the tear conducting passages, often resulting in overflow of fluid from the eye onto the cheek
Number of paths to term: 1
