Clinical spectrum of congenital optic nerve hypoplasia: review of 51 patients / Dov MARGALITH in Developmental Medicine & Child Neurology, 26-3 (June 1984)

Public ISBD [article]  inDevelopmental Medicine & Child Neurology > 26-3 (June 1984) . - p.311-322 Titre : Clinical spectrum of congenital optic nerve hypoplasia: review of 51 patients Type de document : Texte imprimé et/ou numérique Auteurs : Dov MARGALITH, Auteur ; James E. JAN, Auteur ; Andrew Q. MCCORMICK, Auteur ; Wah Jun TZE, Auteur ; Jocelyne LAPOINTE, Auteur Année de publication : 1984 Article en page(s) : p.311-322 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Fifty-one patients with congenital optic nerve hypoplasia (CONH) were reviewed. It was found that the risk of having an affected child is higher in an adolescent mother, and that maternal alcohol or drug abuse may be important factors. Frequently the disorder is associated with other neuropsychiatric handicaps, and with neuro-endocrine abnormalities. The findings suggest that CONH probably is not a homogeneous group of disorders; some may be caused by primary failure of differentiation of the retinal ganglion cells, while others may be the product of an acquired transsynaptic degeneration of optic-nerve fibres.

Eye-pressing by visually impaired children / James E. JAN in Developmental Medicine & Child Neurology, 25-6 (December 1983)

Public ISBD [article]  inDevelopmental Medicine & Child Neurology > 25-6 (December 1983) . - p.755-762 Titre : Eye-pressing by visually impaired children Type de document : Texte imprimé et/ou numérique Auteurs : James E. JAN, Auteur ; Eileen SCOTT, Auteur ; Donald E. NEWMAN, Auteur ; Roger D. FREEMAN, Auteur ; Andrew Q. MCCORMICK, Auteur ; William D. ROBERTSON, Auteur Année de publication : 1983 Article en page(s) : p.755-762 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Many children with severely impaired sight exhibit stereotyped mannerisms. Visual self-stimulation, e.g. eye-pressing and light-gazing, normally is restricted to the visually impaired; prolonged eye-pressing is the most common. This behaviour depends on onset of visual impairment, age, degree and quality of residual light, type of ocular abnormality, the presence of additional handicaps, and the activities in which the child is involved. Children with bilateral optic-nerve defects never press their eyes; those with retinal disorders tend to press vigorously. A possible physiological explanation is that self-stimulation occurs when the demand of the brain for meaningful visual information is not adequately met.

Permanent cortical visual impairment in children / Sharon WHITING in Developmental Medicine & Child Neurology, 27-6 (December 1985)

Public ISBD [article]  inDevelopmental Medicine & Child Neurology > 27-6 (December 1985) . - p.730-739 Titre : Permanent cortical visual impairment in children Type de document : Texte imprimé et/ou numérique Auteurs : Sharon WHITING, Auteur ; James E. JAN, Auteur ; Andrew Q. MCCORMICK, Auteur ; Olof FLODMARK, Auteur ; Peter K. H. WONG, Auteur ; Kevin FARRELL, Auteur Année de publication : 1985 Article en page(s) : p.730-739 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : 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 previously recognised, and should be suspected when there is greater delay in visual development in other areas and the degree of visual loss is unexplained by ocular findings. Using traditional criteria for cortical blindness may mean that many children are not diagnosed, which has serious implications for their rehabilitation.
