  2. 1. Glaucoma Characteristics and Risk Factors - Results from Malmö Eye Survey

    Author : Kirsti Grødum; Oftalmologi (Malmö); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vascular disease; Ophtalmology; Oftalmologi; myopia; optic disc hemorrhages; mortality; refraction; glaucoma; population screening;

    Abstract : This thesis is based on data from a large glaucoma screening, comprising 32, 918 elderly citizens of Malmö and data from retrospective analysis of glaucoma patients’ charts from the Eye Department of Malmö University Hospital. The definition of glaucoma was based on reproducible visual field defects and/or glaucomatous optic nerve head damage in both groups. READ MORE

  4. 2. Peripheral Optics of the Human Eye:Applied Wavefront Analysis

    Author : Dmitry Romashchenko; Linda Lundström; Peter Unsbo; Geunyoung Yoon; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optik och fotonik; Optics and Photonics;

    Abstract : 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. 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. Myopia control and peripheral vision

    Author : Petros Papadogiannis; Linda Lundström; Peter Unsbo; Nicola Logan; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; myopia; peripheral vision; psychophysics;

    Abstract : The rapid rise in myopia prevalence has caused an urgent need for effectivemyopia control interventions. This thesis investigates the role of theperipheral optics of the human eye in myopia progression. It was initiallybelieved that the axial elongation of the myopic eye is caused only by thedefocus signals presented to the central retina. READ MORE

  7. 5. Refractive surgery with the ArF excimer laser (photorefractive keratectomy) : surgical technique, wound healing and refractive results

    Author : Heléne Hamberg-Nyström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Photorefractive keratectomy; excimer laser; comparison; centration; contrast sensitivity; night vision; endothelial cell; epithelial thickness; multipassmultizone; multizone; haze; saccades; hyaluronan; myopic regression; reoperation; wound healing.;

    Abstract : Excimer lasers have been adapted to treat refractive errors in the human eye since 1987. By remodeling the corneal surface, myopia and astigmatism can be corrected. The investigations herein were performed during a time period when the surgical technique development was extensive. READ MORE
