Cerebral Visual Impairment in Children

Development of visual acuity in children with cerebral visual impairment.

OBJECTIVE To study the development of visual acuity in term-born children with cerebral visual impairment and a history of neonatal hypoxic-ischemic encephalopathy. METHODS We studied 19 term-born children, aged 6 months to 6 years, with moderate to severe neonatal hypoxic-ischemic encephalopathy and behaviors indicative of cerebral visual impairment. Longitudinal measures of grating acuity w...

Visual impairment in children.

Visual behaviours of neurologically impaired children with cerebral visual impairment: an ethological study.

BACKGROUND/AIMS Visual functions of neurologically impaired children with permanent cerebral visual impairment (CVI) can be difficult to determine. This study investigated the behavioural profile of CVI children by means of ethological observations in order to gain a better understanding of their visual functions. METHODS Video registrations of nine subjects who were unable to undergo more or...

Understanding cortical visual impairment in children.

This article presents a review of the literature and a case study on a child with cortical visual impairment. The literature review covers the diagnosis, etiology, prevalence, prognosis, and a comparison of the differences between children with cortical visual impairment and those with ocular impairment. The case study presents occupational therapy intervention strategies specific to cortical v...

Visual impairment in very low birthweight children.

AIMS To compare the visual function of a cohort of very low birthweight (VLBW) children in early adolescence with that of their normal birthweight peers; to correlate visual impairment in this group with available perinatal data; and to examine the relation between the visual ability of VLBW children and their cognitive and motor skills. METHODS As part of a long term neurodevelopmental study...
