  1. 1. Improving Peripheral Vision Through Optical Correction and Stimulus Motion

    Författare :Peter Lewis; Peter Unsbo; Linda Lundström; Jörgen Gustafsson; Michael Crossland; Linnéuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; absolute central scotoma; central visual field loss; eccentric viewing; preferred retinal locus; open-view aberrometer; off-axis refractive errors; eccentric correction; dynamic visual acuity; spatial contrast sensitivity; temporal contrast sensitivity; spatio-temporal contrast sensitivity; Optometry; Optometri; Biomedical Sciences; Biomedicinsk vetenskap;

    Sammanfattning : The loss of central vision subsequent to macular disease is often extremely debilitating. People with central field loss (CFL) must use other peripheral areas of the retina in order to see; areas with inferior resolution capacity, which are also affected by off-axis optical errors.

  3. 2. Peripheral Optics of the Human Eye:Applied Wavefront Analysis

    Författare :Dmitry Romashchenko; Linda Lundström; Peter Unsbo; Geunyoung Yoon; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optik och fotonik; Optics and Photonics;

    Sammanfattning : I denna avhandling används vågfrontsanalys för att studera ögats perifera optik med betoning på dess betydelse för utvecklingen av närsynthet (myopi). Syftet är att hitta egenskaper i den perifera bildkvalitén som skulle kunna användas av ögat för att reglera dess tillväxt. LÄS MER

  4. 3. Autonomic reactivity in muscle pain : clinical and experimental assessment

    Författare :Nebojsa Kalezic; Eugene Lyskov; Stein Knardahl; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; autonomic reactivity; stress; chronic pain; experimental pain; back; shoulder; neck; Physiology; Fysiologi; Physiology;

    Sammanfattning : There are numerous indications of possible involvement of the autonomic nervous system in the genesis of chronic pain. The possibility exists that sympathetic activation is related to motor dysfunction and changes in sensory processing, which have otherwise been implicated in musculoskeletal disorders. LÄS MER

  5. 4. Hand grip strength and postural control among individuals with and without Chronic Obstructive Pulmonary Disease : Epidemiological and motion laboratory studies

    Författare :Viktor Strandkvist; Ulrik Röijezon; Anne Lindberg; Caroline Stridsman; Agneta Larsson; André Nyberg; Luleå tekniska universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysioterapi; Physiotherapy;

    Sammanfattning : BackgroundChronic obstructive pulmonary disease (COPD) is estimated to affect approximately 8%–10% of all adults. The disease is considered to be a heterogenic syndrome with systemic effects, in which comorbidities including cardiovascular diseases, muscle dysfunction and fatigue are common. LÄS MER

  7. 5. Intraocular pressure : clinical aspects and new measurement methods

    Författare :Gauti Jóhannesson; Christina Lindén; Per Hallberg; Anders Eklund; Boel Bengtsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intraocular pressure; glaucoma; tonometry; ISO; LASEK; CCT; curvature; Ophtalmiatrics; Oftalmiatrik; Ophtalmology; oftalmiatrik;

    Sammanfattning : Intraocular pressure (IOP) measurement is a routine procedure and a fundament in glaucoma care. Elevated IOP is the main risk factor for glaucoma, and to date, reduction of IOP is the only possible treatment. In a retrospective clinical material, the prevalence of open angle glaucoma was estimated on the west coast of Iceland. LÄS MER
