Persistent hyperplastic primary vitreous (PHPV) is a rare developmental disorder of childhood. It is one of the differentials of leukocoria, which should be ruled out. Characteristic presence of persistent hyaloid artery, and absence of contrast enhancement or calcification, differentiates it from other conditions like retinoblastoma or Coat's disease.

Lacrimal gland enlargement and PHPV does not seem to have a direct association, however does explain excessive tears in this patient.
