The development of visual function in normal and neurologically abnormal preterm and fullterm infants / Ana MORANTE in Developmental Medicine & Child Neurology, 24-6 (December 1982)
[article]
Titre : The development of visual function in normal and neurologically abnormal preterm and fullterm infants Type de document : Texte imprimé et/ou numérique Auteurs : Ana MORANTE, Auteur ; Victor DUBOWITZ, Auteur ; Lilly M. S. DUBOWITZ, Auteur ; Malcolm I. LEVENE, Auteur Année de publication : 1982 Article en page(s) : p.771-784 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Pattern preference for four different pairs of patterns, and visual acuity based on the ability to distinguish black and white stripes of different widths, were compared in neurologically normal and abnormal preterm infants at 36 and 40 weeks postmenstrual age and in normal and abnormal fullterm infants in the newborn period and again at four and six weeks of age. The study aimed to chart the maturation process of these visual functions in the neonatal period and to assess their predictive value in the neurologically abnormal infant. Part I of the study deals with the normal infant and Part II with the abnormal infant. In Part I, the maturation process for both visual functions in newborn preterm infants of increasing gestational age is compared with longitudinal assessment of postnatal maturation of these functions in preterm infants up to 40 weeks postmenstrual age. Up to 36 weeks postmenstrual age the functions were comparable in the maturing preterm infants and the newborn infants of comparable postmenstrual age, but at 40 weeks the preterm infants did less well than the fullterm newborn infants. In Part II, the abnormal fullterm infants demonstrated a significantly poorer pattern preference at the initial and subsequent examination. Visual acuity was significantly poorer at the initial examination but less marked at follow-up. The abnormal preterm infants showed poorer pattern preference and visual acuity at both 36 and 40 weeks postmenstrual age. Compared with neurologically abnormal infants without intraventricular haemorrhage (IVH), preterm infants with IVH showed no significant difference in pattern preference at 36 and 40 weeks, but a significant deficit in visual acuity.

Titre : Visual function in the preterm and fullterm newborn infant Type de document : Texte imprimé et/ou numérique Auteurs : Lilly M. S. DUBOWITZ, Auteur ; Victor DUBOWITZ, Auteur ; Ana MORANTE, Auteur ; M. VERGHOTE, Auteur Année de publication : 1980 Article en page(s) : p.465-475 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Visual function in the preterm newborn infant has been studied by the visual orientation (tracking) technique of the Brazelton neurobehavioural assessment, and by the pattern preference and fixation techniques of Frantz. Both these methods demonstrated the presence of discriminative visual function by 31 to 32 weeks gestation, which by 34 weeks reaches a maturity comparable to the pattern found in fullterm infants. Sequential studies at weekly intervals of preterm infants, ranging in gestation from 28 to 32 weeks, have shown a similar pattern of development of visual function to that of the newborn infant of equivalent postconceptional age. However, comparative studies of visual orientation and pattern preference in the same infants have not shown a close correlation. The assessment of visual function in the preterm newborn infant is a valuable milestone. Aberrations may reflect a dificit in visual function itself, a more broad-based deficit in neurological function, or possibly a response to a generalised illness.
