1. 1. Transverse Chromatic Aberration and Vision: Quantification and Impact across the Visual Field

   Författare :Simon Winter; Linda Lundström; Stephen Burns; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transverse chromatic aberration; lateral chromatic aberration; visual optics; peripheral vision; central vision; dispersion; ophthalmic optics and devices; optical effects on vision; retinal imaging; myopia; human eye; Fysik; Physics;

   Sammanfattning : The eye is our window to the world. Human vision has therefore been extensively studied over the years. However, in-depth studies are often either limited to our central visual field, or, when extended to the periphery, only correct optical errors related to a narrow spectrum of light. LÄS MER

3. 2. Fetal Alcohol Spectrum Disorders in Children and Young Adults with an emphasis on ophthalmology

   Författare :Emelie Gyllencreutz; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fetal Alcohol Syndrome; Optic Nerve; Optical Coherence Tomography; Strabismus; Vision; Visual Perception; Quality of Life;

   Sammanfattning : Introduction: Fetal alcohol spectrum disorders (FASD) are a group of disorders caused by prenatal alcohol exposure (PAE). The most severe and most studied FASD condition is fetal alcohol syndrome. Other conditions include partial fetal alcohol syndrome and alcohol-related neurodevelopmental disorder. LÄS MER

4. 3. 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.

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

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

   Sammanfattning : 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. LÄS MER

7. 5. 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
