Jethani J, Jethani M. Flash visual evoked potentials in patients with periventricular leucomalacia in children less than 1 year of age. [11] These cytokines are toxic to the developing brain, and their activity in an effort to respond to specific areas of damaged tissue is believed to cause "bystander damage" to nearby areas that were not affected by the original insult. However, other differential diagnoses include ischemic, infectious, inflammatory, compressive, congenital, and toxic-nutritional etiologies. Association between perinatal hypoxic-ischemia and periventricular leukomalacia in preterm infants: A systematic review and meta-analysis.

The extent of PVL may be further assessed using fMRI with various visual stimuli. Submissions should not have more than 5 authors. Kinney HC. The optic radiations, which may be damaged in the periventricular region, originate from the lateral geniculate nuclei and are topographically organized both anatomically and functionally. Periventricular leukomalacia is caused by insufficient oxygen in the baby (hypoxemia and hypoxia) and/or restricted or decreased blood flow in the brain (ischemia). Acta Paediatr. The features of PVL in childhood are described elsewhere and this article will review the neuro-ophthalmic features of PVL in adult patients who may present later in life with otherwise unexplained findings that may mimic adult strabismus or optic neuropathy .

Semin Perinatol. There is loss of normal periventricular white matter, with associated gliosis and thinning of the corpus callosum. Premyelinating oligodendrocytes, which predominate in periventricular regions during the window of vulnerability to PVL (24 to 34 postconceptional weeks), are the targets of this free radical injury, and suffer cell death.

Liu GT, Volpe NJ, Galetta SL. There are many ways to receive support: The condition involves the death of small areas of brain tissue around fluid-filled areas called ventricles. Made available by U.S. Department of Energy Office of Scientific and Technical Information . The ventricles are fluid-filled chambers in the brain. The first use of the term PVL was by Banker and Larroche in 1962, although the gross . The prognosis of patients with PVL is dependent on the severity and extent of white matter damage.

Delayed motor development of infants affected by PVL has been demonstrated in multiple studies. Post-geniculate body lesions in adults involving the optic radiations or the occipital cortex do not produce loss of visual acuity, an RAPD, or optic atrophy. The percentage of individuals with PVL who develop cerebral . [6] One of the earliest markers of developmental delays can be seen in the leg movements of affected infants, as early as one month of age. Online ISSN:1526-632X, The most widely read and highly cited peer-reviewed neurology journal. Because the vascular supply of the periventricular region of the brain in utero remains immature late into term, PVL may arise from neonatal hypoglycemia, hypoxia, seizure, or infection in the third trimester or perinatally5,6. This delicate brain tissue is called white matter, and white matter is the tissue responsible for the production of myelin, a fatty substance that covers and protects the nerve axons, allowing impulses to . Because white matter injury in the periventricular region can result in a variety of deficits, neurologists must closely monitor infants diagnosed with PVL in order to determine the severity and extent of their conditions. In cases where perinatal hypoxic brain injury has already occurred, use of hypothermia as neuroprotective treatment has been studied16. Table 4: Characteristic features of PVL on CT and on MRI.
