  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. Quantitative assessment of glaucoma by artificial intelligence estimation of the waist of the nerve fiber layer in the optic nerve head

    Författare :Konstancija Kisonaite; Per Söderberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicinsk vetenskap; Medical Science; Ophtalmology; Oftalmiatrik;

    Sammanfattning : Glaucoma is a chronic progressive disease that causes loss of retinal ganglion cells, which impairs the visual field. In optic coherence tomography (OCT) image, the retinal ganglion cell (RGC) axons in the optic nerve head (ONH) can be quantified as the minimal thickness from the ONH Pigmental epithelium Central Limit (OPCL) to the Inner limit of the Retina Closest Point (IRCP).

  4. 3. On visual impairment in Swedish children

    Författare :Jonas Blohmé; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ophtalmology; Sweden; sociology; mortality; outcome; epidemiology; registration; childhood blindness; Visual impairment; children; Oftalmologi;

    Sammanfattning : Knowledge of the epidemiology of visual impairment in children forms one of the cornerstones in paediatric ophthalmology. To gain an overview of the situation in Sweden an epidemiological study was performed. Totally 2373 visually impaired children were found, giving an age-specific prevalence of 10,9/10 000. Childhood blindness (i. LÄS MER

  5. 4. Diffusion Tensor Imaging and Tractography of the Visual Pathways

    Författare :Ylva Lilja; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diffusion tensor imaging; Visual pathways; Tractography; Temporal lobe resection; Pituitary adenomas;

    Sammanfattning : The visual pathways are essential for human vision, stretching from the retinas of the eyes, via the anterior visual pathways and the optic radiations, to the primary visual cortex in the occipital lobe. Injury to these structures will lead to visual impairment – from small deficits to blindness. LÄS MER

  7. 5. Experimental Vitreous Substitution

    Författare :Henrik Barth; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Retinal Detachment; Vitreous Body : surgery; Retina cytology metabolism surgery; Retina: Function; Retina: Inflammation; Retinal Detachment; Vitreous Body : surgery; Vitreous substitute; Vitrectomy;

    Sammanfattning : Blindness and visual disability are common following vitreoretinal pathologies such as open globe injury, proliferative diabetic retinopathy, and rhegmatogenous retinal detachment (RRD). These conditions often necessitate surgical intervention using vitrectomy with a tamponading vitreous substitute. LÄS MER
