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

    University dissertation from Växjö : Linnaeus University Press

    Author : Peter Lewis; Linnéuniversitetet.; [2016]
    Keywords : 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;

    Abstract : 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.

  2. 2. Eccentric correction in central visual field loss

    University dissertation from Växjö : Linnaeus University Press

    Author : Jörgen Gustafsson; Lunds universitet.; Lund University.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Synskador och blindhet; Optik och seende;

    Abstract : It is not often that one is instantaneously able to apply the results of basic research. This work is an example of such an exception. A widely held conviction has been that human peripheral vision could not be improved through optical correction. It w. READ MORE

    Abstract : Popular Abstract in Swedish För människor med centrala skotom är den excentriska synen den enda som finns att tillgå. Också för den som lär sig att använda sin excentriska syn är denna sämre än den centrala synen, och det av två helt olika skäl: att ögonoptiken kan ge stora avbildningsfel excentriskt respektive att näthinnan utanför makula har en lägre funktion.

  4. 4. Optimal Use of Peripheral Vision

    University dissertation from Kalmar, Växjö : Linnaeus University Press

    Author : Karthikeyan Baskaran; Linnéuniversitetet.; [2012]
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 5. Wavefront Aberrations and Peripheral Vision

    University dissertation from Stockholm : KTH

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

    Abstract : 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. READ MORE
