Other conditions linked to PVL include: In mild cases, some babies may not have any symptoms. The differentiating features of true glaucoma in adulthood versus pseudoglaucomatous cupping from PVL are described in Table 2. Preventing or delaying premature birth is considered the most important step in decreasing the risk of PVL. This tissue is located near the fluid-filled ventricles in the brain. 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. The disorder is diagnosed with an ultrasound of the head. Periventricular leukomalacia involves death of the white matter surrounding the lateral ventricles in fetuses and infants. The site is secure. We propose that the prolonged hypoxia and ischemia produce a "no reflow" phenomenon causing brain edema (more pronounced in the white matter); this resulted in infarctions of white matter in the periventricular arterial end and border zones. The differentiating features on examination of pre-chiasmal versus post chiasmal and pre-geniculate versus post-geniculate body visual loss are described in Table 1.
