Permanent Cortical Visual Impairment in Children

Abstract: SUMMARY Fifty patients with permanent cortical visual impairment were evaluated. They had a characteristic behaviour profile, usually with residual sight but poor visual attention. 30 of the 50 also had damage to the anterior visual pathway. Visual evoked potential mapping was shown to have a clear advantage over visual evoked responses, and using that in conjunction with CT and clinical data enabled several subgroups of cortical visual impairment to be identified. The diagnosis probably is more common than pr… Show more

“…Over the last decade the term cerebral visual impairment (CVI) has come to indicate the clinical picture of the infant and child who present with visual impairment due to a cerebral pathology, generally in the retrogeniculate visual pathway (Fooley 1985, Whiting 1985, Jan 1987. The difference between CVI in children and cortical blindness in adults has been clearly defined (Good 1994).…”

“…Furthermore, because the degree of vision loss resulting from a cortical insult is highly variable, rarely complete, and often shows a degree of recovery, many investigators prefer the term CVI to cortical blindness to avoid the dismal prognostic implications suggested by the term blindness. 296,613 We have advocated the term subcortical visual loss for the focal white matter lesions confined to the optic radiations in premature infants (periventricular leukomalacia). 76 Despite the apparent selective white matter involvement on neuroimaging, however, these patients often have a more global brain injury, with many symptoms referable to higher cortical dysfunction.…”

“…613 The most common organisms include Haemophilus influenzae, pneumococci, and streptococci. The CVI occurs within a week of the onset of meningitis in about half the cases, and within 1 month of the onset in almost all cases.…”

“…Thus, residual function may simply reflect the still functioning portions of the visual cortex. 33 However, most investigators who have studied these children seem to believe that some unique mechanism involving 'plasticity' of the infant brain is an essential factor in the apparent visual 'recovery' that is described so frequently in these children. 5,28,34 This is in sharp contrast to the situation in adults where the consensus is that visual loss associated with damage to the visual cortex is permanent and irrepairable.…”
