  2. 1. Ocular function and morphology in humans and rabbits exposed to vigabatrin medication

    Author : Ulrika Kjellström; Lund Oftalmologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vimentin; PKC-alpha; visual field defects; optical coherence tomography; full-field electroretinography; GABA; vigabatrin;

    Abstract : Vigabatrin is an antiepileptic drug that is known to cause visual field defects and retinal dysfunction measured by full-field electroretinography (ff-ERG). Underlying mechanisms have not yet been elucidated. READ MORE

  4. 2. Diffusion Tensor Imaging and Tractography of the Visual Pathways

    Author : Ylva Lilja; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diffusion tensor imaging; Visual pathways; Tractography; Temporal lobe resection; Pituitary adenomas;

    Abstract : The visual pathways are essential for human vision, stretching from the retinas of the eyes, via the anterior visual pathways and the optic radiations, to the primary visual cortex in the occipital lobe. Injury to these structures will lead to visual impairment – from small deficits to blindness. READ MORE

  5. 3. Improved computerized perimetric threshold strategies

    Author : Boel Bengtsson; Oftalmologi (Malmö); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; probability maps; normal limits; test time; clinical testing; test strategies. glaucoma; test algorithms; false positive answers; Visual field testing; computerized perimetry; Ophtalmology; Oftalmologi;

    Abstract : Perimetric threshold examination is the most important method for diagnosing and monitoring patients with glaucoma. Such examination, however, is time-consuming and often difficult for the elderly patients in whom glaucoma is prevalent. Shorter test strategies have been proposed, but unfortunately also with lower test quality. READ MORE

  6. 4. Visual dysfunction and ocular signs associated with periventricular leukomalacia in children born preterm

    Author : Lena Jacobson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : preterm; retinopathy of prematurity; periventricular leukornalacia; magnetic resonance imaging; delayed visual maturation; visual acuity; crowding; visual field; cognitive visual dysfunction; optic disc; cupping; eye movements; nystagmus; strabismus; reading;

    Abstract : The immature visual system is vulnerable to adverse events in infants born preterm. Both retinopathy of prematurity and periventricular leukomalacia may affect visual function and ocular appearance. READ MORE

  7. 5. The Rarebit fovea test : a new measure of visual function

    Author : Maria Nilsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Rarebit Fovea Test; Rarebit Perimetry; foveal function; fixation; diabetes; cataract; binocular summation;

    Abstract : Visual acuity (VA) measurement by the use of letter charts is the most frequently used method for testing foveal function. However, since a decimal visual acuity of 1. READ MORE
