Periventricular Leukomalacia in Patients With Pseudo-glaucomatous Cupping.

Periventricular leukomalacia (PVL) is a structural loss of white matter pathways that carry visual information from the lateral geniculate bodies to the visual cortex. It is observed radiologically in patients with a history of prematurity and is associated with visual field (VF) defects and optic disc cupping. Advances in perinatal care have improved survival for premature babies, so many now present as adolescents and adults to comprehensive eye doctors who are unaware of the relationship of cupping, field defects, and prematurity and who may diagnose manifest or suspected normal tension glaucoma. We describe 2 such patients to raise awareness of this entity.
