  1. 1. Peripheral Vision Adaptive Optics and Psychophysics

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Robert Rosén; KTH.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is about our peripheral vision. Peripheral vision is poor compared to central vision, due to both neural and optical factors. The optical factors include astigmatism, defocus and higher order aberrations consisting mainly of coma. Neurally, the density of ganglion cells decreases towards the periphery, which limits the sampling density. LÄS MER

  2. 2. Tourism Development in Peripheral Areas Processes of Local Innovation and Change in Northern Sweden

    Detta är en avhandling från Östersund, Sweden : Mid Sweden University

    Författare :Patrick Brouder; Mittuniversitetet.; [2013]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; change; development; evolution; peripheral; Sweden; tourism.;

    Sammanfattning : Tourism has reached almost all regions of the world and has had a notable growth in the peripheral regions of Europe. Attempts at tourism development in rural and peripheral areas have resulted in widely varying outcomes and have often been undertaken as a last resort by communities. LÄS MER

    Sammanfattning : Peripheral neuropathy is a common complication among patients with diabetes mellitus, but whether peripheral neuropathy is present in individuals with impaired glucose tolerance (IGT) is debatable. In order to identify and diagnose peripheral neuropathy correctly, it is important to evaluate diagnostic tools that can be implemented in routine health care to assess both large and small nerve fibre function.

  4. 4. Optimal Use of Peripheral Vision

    Detta är en avhandling från Kalmar, Växjö : Linnaeus University Press

    Författare :Karthikeyan Baskaran; Linnéuniversitetet.; [2012]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; off-axis refractive errors; peripheral aberrations; aberrometers; central visual field loss; preferred retinal locus; eccentric viewing; absolute central scotoma; adaptive optics; eccentric correction.; Optometry; Optometri;

    Sammanfattning : People who lose their central vision have to rely on their peripheral vision for all visual tasks. The ability to resolve fine details in the periphery is reduced due to retinal limitations and the optical aberrations arising from the use of off-axis vision. LÄS MER

  5. 5. Wavefront Aberrations and Peripheral Vision

    Detta är en avhandling från Stockholm : KTH

    Författare :Linda Lundström; KTH.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optics; Human eye; Aberrations; Peripheral vision; Central visual field loss; NATURAL SCIENCES Physics Other physics Optics; NATURVETENSKAP Fysik Övrig fysik Optik;

    Sammanfattning : Failing eyesight causes a dramatic change in life. The aim of this project is to help people with large central visual field loss to better utilize their remaining vision. Central visual field loss means that the person has to rely on peripheral vision since the direct vision is lost, often due to a dysfunctional macula. LÄS MER
