This is the overproduction of tears, principally caused by emotional or reflex stimulation of the lacrimal gland. Chronic lacrimation may deplete the lacrimal gland to such an extent that tear formation appears normal or reduced.

Major causes:

  • corneal foreign body, abrasion or inflammation
  • entropion

Less frequently:

  • crocodile tears
  • psychic stimulation - crying
  • cholinergic or anticholinesterase drugs
  • dacryoadenitis
  • lacrimal gland tumours
