Also found in: Dictionary, Thesaurus.

hyperlacrimation

Overflow of tears due to excessive secretion by the lacrimal gland. It may be caused by drugs (e.g. pilocarpine), strong emotion; or as a reflex from trigeminal stimulation by an inflamed eye; or irritation of the cornea or conjunctiva by a chemical irritant in the air; cold wind; or a foreign body in the eye. The main symptoms are discomfort and blurring of vision and sometimes embarrassment. Management depends on the cause. Syn. hypersecretion. See epiphora.
