Periventricular leukomalacia (PVL) is a type of brain injury most common in very premature babies. Clinical research uses human volunteers to help researchers learn more about a disorder and perhaps find better ways to safely detect, treat, or prevent disease. PVL involving the optic radiations is one of the most common causes of visual impairment in patients with a history of prematurity4. Despite the varying grades of PVL and cerebral palsy, affected infants typically begin to exhibit signs of cerebral palsy in a predictable manner.

Children with PVL should receive regular medical screenings to determine appropriate interventions. Although post-geniculate lesions in the fully developed adult brain do not usually produceoptic atrophy (including band atrophy), ophthalmologists caring for adult patients with a history of PVL need to be aware that in utero events cortical events can cause transsynaptic degeneration and secondary optic atrophy, band atrophy, or pseudo-glaucomatous cupping. Microglia, which express toll-like receptors to bacterial products such as lipopolysaccharide, are increased in PVL white matter and may contribute to the injury. Periventricular leukomalacia, also known as white matter injury of prematurity, is a brain injury that occurs prior to 33 weeks of gestation.
