  2. 1. Optimal Use of Peripheral Vision

    Author : Karthikeyan Baskaran; Jörgen Gustafsson; Peter Unsbo; Staffan Carius; Michael Crossland; Linnéuniversitetet; []
    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

  4. 2. Improving Peripheral Vision Through Optical Correction and Stimulus Motion

    Author : Peter Lewis; Peter Unsbo; Linda Lundström; Jörgen Gustafsson; Michael Crossland; Linnéuniversitetet; []
    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.

  5. 3. Age-related maculopathy and macular degeneration : New diagnostic and therapeutic procedures

    Author : Christina Frennesson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Age-related maculopathy (ARM) may progress into age-related macular degeneration (AMD), which is often disastrous to near vision and reading. Currently used treatment is generally not successful in a long-term perspective. Therefore, searching for an early detection of functional disturbances as well as for prophylactic treatment appears important. READ MORE
