  1. 6. Electrophysiology and optical coherence tomography in acquired and hereditary retinal disorders

    Författare :Patrik Schatz; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Retinal degeneration; multifocal ERG; Oftalmologi; Ophtalmology; OCT;

    Sammanfattning : In this thesis, retinal function in general, as well as central retinal function and structure are described in selected forms of acquired and hereditary retinal disorders, in order to improve our understanding of underlying pathogenic mechanisms. This comparison has been made possible during the last years, through the relatively recent development of multifocal ERG (mfERG) and optical coherence tomography (OCT) for the analysis of central retinal function and structure, respectively.

  3. 7. Retinal pigment epithelial cells, oxidative stress and lipofuscin : relation to age-related macular degeneration

    Författare :Staffan Sundelin; Stefan Seregard; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : In developed countries, age-related macular degeneration (AMD) is the most common cause of loss of central vision in people over the age of 65. The retinal pigment epithelium (RPE) appears to be the site of early pathological changes in AMD. LÄS MER

  4. 8. Intracellular mechanisms in rd1 mouse retinal degeneration

    Författare :Leif Johnson; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ophtalmology; Neuroprotection; Photoreceptor; Retinitis Pigmentosa; Oftalmologi;

    Sammanfattning : Retinitis pigmentosa (RP) is an inherited disorder and the leading cause of visual impairment in the working age population. It is caused by a number of different genetic mutations, all of which cause the rod photoreceptors to degenerate. As the rods become few in numbers, the cones will also begin to die, resulting in total blindness. LÄS MER

  5. 9. Models of Retinal Development and Disease

    Författare :Minas Hellsand; Finn Hallböök; Emma Andersson; Department of Cell and Molecular Biology Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Developmental neurobiology; retinal organoids; retinoblastoma; MYCN; Stargardt disease; Bardet-Biedl syndrome; model systems;

    Sammanfattning : For a model of a human disease to be valid and useful, it is important that key genotypic and phenotypic traits are shared between model system and human. The work in this thesis has been focused on generating new and characterizing spontaneous models of three genetic disorders affecting the retina: retinoblastoma, a childhood cancer with its origin in the fetal retina, Stargardt disease, a juvenile form of macular degeneration, and Bardet-Biedl syndrome, a pleiotropic ciliopathy featuring retinal degeneration.

  7. 10. Bothnia dystrophy, a clinical, genetical and electrophysiological study

    Författare :Marie Burstedt; Ola Sandgren; Ola Textorius; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ophtalmology; retinal pigment epithelium; retinitis pigmentosa; neural retina; electroretinogram; cellular retinaldehyde-binding protein; dark adaptometry; retinal degeneration; Oftalmiatrik; Ophtalmology; Oftalmologi; Ophtalmology; oftalmiatrik;

    Sammanfattning : A high frequency of retinitis pigmentosa (RP) is found in Northern Sweden. In an inventory of autosomal recessive RP patients in Västerbotten County, a great number of cases with a unique phenotype was noticed, denoted Bothnia Dystrophy (BD). LÄS MER
