noun, plural: epiphoras

(1) (mycology) A genus in the Dothideomycetes order

(2) (entomology) A genus in the Sturniidae family

(3) (pathology) An excessive tear production, especially due to an eye irritation


In mycology, Epiphora (or Plectocarpon) is a fungus genus in Dothideomycetes order whereas in entomology, Epiphora is a moth genus in the Sturniidae family. Epiphora moths are native to the sub-Saharan Africa. An example of moth species belonging to this genus is E. rectifascia, a moth found in Camerron, Kenya, Nigeria, Tanzania, Zambia, Uganda, and the Democratic Republic of Congo.

In pathology, epiphora refers to the excessive tear production, especially due to an eye irritation. The tears are produced in excess by the lacrimal glands. This condition also results when the tear outflow tract is obstructed. The latter may be classified based on anatomical part involved, e.g. nasolacrimal duct, ectropion, punctal, and canalicular obstructions. The obstruction may be associated with aging, conjunctivochalasis infection, and rhinitis. Epiphora in infants may be due to a failure of the nasolacrimal duct to open. Trauma such as nasoethmoid fractures, nose or eyelid tissue trauma may also lead to this condition.
