Persistent hyperplastic primary vitreous (PHPV), also known as persistent fetal vasculature (PFV), is a rare congenital developmental anomaly of the eye that results following failure of the embryological, primary vitreous and hyaloid vasculature to regress.[1] It can be present in three forms: purely anterior (persistent tunica vasculosa lentis and persistent posterior fetal fibrovascular sheath of the lens), purely posterior (falciform retinal septum and ablatio falcicormis congenita) and a combination of both.[1] Most examples of PHPV are unilateral and non-hereditary. When bilateral, PHPV may follow an autosomal recessive or autosomal dominant inheritance pattern.

Symptoms[edit]

The primary vitreous used in formation of the eye during fetal development remains in the eye upon birth and is hazy and scarred.[2] The symptoms are leukocoria, strabismus, nystagmus and blurred vision, blindness.[3]

Causes/association of bilateral PHPV[edit]

  1. Trisomy 13 (Patau syndrome)
  2. Norrie disease
  3. Walker-Warburg syndrome
  4. Autosomal dominant
  5. Autosomal recessive

Diagnosis[edit]

Causes a 'white reflex' in the affected eye (leukocoria), prompting further investigation.

Treatment[edit]

Par plana lensectomy and vitrectomy
