Definition / general
  • Also called retinopathy of prematurity
  • Previously was leading cause of blindness in US
  • Occurs in premature infants given oxygen therapy; related to level and duration of oxygen, degree of prematurity at birth and status as carrier for defect in Norrie disease gene
  • Immature vessels of premature infants are damaged by high or even physiologic oxygen; rarely occurs in term infants
Pathophysiology
  • Oxygen therapy causes vasoconstriction and obliteration of immature retinal vessels in lateral (temporal) retina which causes ischemia and failure of retina to vascularize
  • Then vasoproliferative phase and angiogenesis
  • Vessels grow into vitreous or leak serum or fluid, 25% have associated scarring which causes retinal detachment
