    Författare :Allison Mackey; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The aims of this thesis were to assess the status of childhood hearing screening programmes, primarily in Europe, and to evaluate their performance against the parameters that make up a childhood hearing screening programme, such as test method, protocol, location, screening professional, and age of the infant at screening.

    Sammanfattning : The main causes for monocular visual loss in childhood are amblyopia and injury, and in the case of poor vision in both eyes refractive errors, the principle cause being myopia. Reliable visual acuity testing, reaching children at as young an age as possible, is essential in detecting these conditions and monitoring their treatment. LÄS MER

  4. 18. Assessment of visual contrast function and effects of citicoline treatment in children with visual impairment

    Författare :Aamir Siddiqui; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Purpose: The present studies address the questions if visual dysfunction in severely visually impaired children can be measured with contrast tests high or low, how it relates to their visual abilities assessed with behavioural methods and if visual function in these children can be improved by neuro-pharmacological treatment. Methods: Twenty children aged 6-16 years from the Al-Maktoom school for visually impaired children in Islamabad, Pakistan were included in the first study and 22 children aged 6-14 years in the second study.
