1. 11. Anti-VEGF treatment of patients with diabetic macular edema : Studies of visual acuity, macular edema and patient-reported outcomes

   Författare :Therese Granström; Janeth Leksell; Henrietta Forsman; Elisabet Granstam; Högskolan Dalarna; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hälsa och välfärd; Health and Welfare;

   Sammanfattning : The aim of this thesis was to describe and evaluate visual acuity, macular edema and patientreported outcomes (PRO) following anti-VEGF treatment of diabetic macular edema (DME) patients in a real-world setting. Using a longitudinal study design, a cohort of DME patients was followed from baseline to 1 year after treatment start. LÄS MER

3. 12. Aspects on Function in Age-Related Macular Degeneration

   Sammanfattning : Age-related macular degeneration (AMD) is one of the leading causes of severe visual loss among persons ≥ 60 years. AMD can be categorized in one of three stages: early, intermediate, or late. In early AMD visual symptoms are inconspicuous whereas, in the late stage, severe loss of vision is common. Late AMD has dry and wet forms. LÄS MER

4. 13. Manipulation of Ocular Aberrations in Myopes

   Författare :Baskar Theagarayan; Jörgen Gustafsson; Frank Schaeffel; Linnéuniversitetet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Myopia; Spherical aberration; Accommodation; Contact lens; Visual acuity; Peripheral aberrations; Optometry; Optometri; Optometry; Optometri;

   Sammanfattning : Myopia is a major cause of vision loss throughout the world. High myopia is associated with severe eye diseases like maculopathy, retinal detachment and glaucoma. The prevalence of myopia is increasing, and varies by country and by ethnic group. In some Asian populations the prevalence is 70%-80%. LÄS MER

5. 14. A New Model for Assessment of Change in Visual Function in Diabetes

   Författare :Karl-Johan Hellgren; Malmö Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetic retinopathy; visual function; perimetry;

   Sammanfattning : The purpose of this thesis was to determine whether perimetry using a new model to interpret deterioration or improvement in the visual field can be employed to assess change in visual function over time in diabetes. Diabetic retinopathy has long been considered a microvascular disease, but it is still a matter of debate to what extent diabetes also affects retinal neurons. LÄS MER

7. 15. 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. LÄS MER
