2. 1. Optics for Low Vision Enabling

   Author : Jörgen Gustafsson; Certec - Rehabiliteringsteknik och Design; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Eccentric viewing; Low vision optics; Low vision rehabilitation; People with low vision; Preferred retinal; locus PRL ; Resolution; Visual acuity; Ophtalmology; Medicinsk teknik; Medical technology; Rehabilitering medicinsk och social ; rehabilitation; revalidation; kinesitherapy; Oftalmologi; Physical medicine; Contrast sensitivity; Detection; Eccentric correction; CFL ; Central visual field loss; Central scotoma; Aberrations; Astigmatism;

   Abstract : For people with central visual field loss, eccentric vision is all that they have to rely on. Even for those who learn how to correctly utilize their eccentric vision, it will never be as good as the central for two entirely different reasons: the off-axis optics of the eye can result in large refractive errors, and the low function of the peripheral retina.

4. 2. Re-establishing reading skills of elderly low vision patients : studies on Swedish low vision clinic clients

   Author : Örjan Bäckman; Karolinska Institutet; Karolinska Institutet; Karolinska Institutet; Karolinska Institutet; []
   Keywords : elderly patients; low vision clinic; reading proficiency; cognitive capacity; low vision reading training; low vision rehabilitation; quality of life;

   Abstract : This thesis is based on the project "Reading skills, reading training and technology for the visually handicapped - Prospects for the 1990s," carried out at the Department of Educational Research of the Stockholm Institute of Education 1988-1993. All data were collected in connection with this project. READ MORE

5. 3. Wavefront Aberrations and Peripheral Vision

   Author : Linda Lundström; Peter Unsbo; Austin Roorda; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optics; Human eye; Aberrations; Peripheral vision; Central visual field loss; Optics; 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

6. 4. Vision Beyond the Fovea: Evaluation and Stimuli Properties

   Author : Abinaya Priya Venkataraman; Linda Lundström; Hema Radhakrishnan; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Peripheral vision; Visual optics; Optical correction; Orientation; Stimulus extent; Moving stimulus; Contrast sensitivity; Visual acuity; Central vision loss; Myopia; Biological Physics; Biologisk fysik;

   Abstract : This research is about evaluating vision in the periphery. Peripheral vision is of fundamental importance in the performance of our everyday activities. The aim of this thesis is to develop methods suitable for the evaluation of peripheral vision and to assess how different visual functions vary across the visual field. READ MORE

7. 5. 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
