  1. 1. Evaluation of the visual pathway with ERG, mfERG and mfVEP in inherited eye disorders

    Författare :Lotta Gränse; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; multifocal ERG; Full-field ERG; multifocal VEP; Bothnia Dystrophy; Retinitis pigmentosa; Dominant optic atrophy; Leber`s hereditary optic neuropathy; Oftalmologi; Ophtalmology;

    Sammanfattning : This thesis will describe the clinical phenotypes, with emphasis on electrophysiology, in patients with different hereditary eye diseases and to further evaluate and modify the mfVEP technique for clinical use. Bothnia Dystrophy is a tapetoretinal disorder with a mutation in the RLBP1 gene. LÄS MER

  3. 2. Signal identification for visual electrophysiological recordings. A comparison of signal analysis techniques and their application to clinical electrophysiology of vision

    Författare :Thomas Wright; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Visual Electrophysiology; Signal detection; Signal-to-Noise Ratio; multivariate analysis; spatial-temporal partial least-squares;

    Sammanfattning : Aims: The aim of this thesis was to investigate the use of objective methods for the analysis of visual electrophysiological recordings. Specifically can signal identification algorithms identify electrophysiological signals and can they be applied to improve clinical testing and analysis? Methods: Automated signal identification algorithms were applied to multifocal electroretinogram (mfERG) and visual evoked potential (VEP) recordings. LÄS MER

  4. 3. Disorders of the cerebral white matter in children

    Författare :Ragnhildur Kristjánsdóttir; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; leukoencephalopathy - children - neurological impairments - magnetic resonance imaging - ophthalmology - visual evoked potentials - cerebrospinal fluid - sulfatide - glial fibrillary acidic protein - gangliosides - neurofilament - tau protein - monoamine metabolites;

    Sammanfattning : The aims of this thesis were to describe the clinical spectrum in a large group of children characterised as having an abnormal magnetic resonance imaging (MRI) signal from cerebral white matter (WM) and to study the radiological, clinical and ophthalmological features in that subgroup where aetiology was unknown. We also wanted to look at biochemical markers in the cerebrospinal fluid (CSF) to elucidate pathological processes which were responsible for the WM abnormalities. LÄS MER
