1. Optimal Use of Peripheral Vision
Sammanfattning : 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. LÄS MER
2. Prevalence of refractive errors and incidence of myopia in Swedish schoolchildren
Sammanfattning : PurposeThe aim of this thesis was to investigate the prevalence, incidence, and risk factors for myopia development in a cohort of Swedish schoolchildren. The specific goals were: - to recruit a cohort of children aged 8 to 16 years and to follow the cohort over a period of 24 months with regular study visits; - to investigate the predictive value of relative peripheral error and other optical parameters for the prevalence and incidence of myopia; - to determine and investigate the predictive value of genetic and environmental factors, and structural characteristics of the eye to the incidence of myopia.

3. Improving Peripheral Vision Through Optical Correction and Stimulus Motion
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.

4. Studying prevalence using capture-recapture methods : visual impairment in Portugal
Sammanfattning : Visual impairment (VI) due to eye diseases remains a significant healthproblem worldwide and, also, in Europe. There are an estimated 15 million peoplesuffering from moderate or severe visual impairment in Western Europe. LÄS MER
5. Manipulation of Ocular Aberrations in Myopes
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
