  2. 1. Experimental porcine models of retinal ischemia

    Author : Håkan Morén; Lund Oftalmologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; retinal ischemia; animal model; multifocal electroretinography; intraarterial coiling; retinal vasculature;

    Abstract : Retinal ischaemia resulting from e.g. diabetes, vein thrombosis or arterial occlusion, is one of the major causes of visual impairment and blindness. Although new methods of treatment are being developed, there is still a need for more effective pharmacological forms of treatment. READ MORE

  4. 2. Optical Coherence Tomography for Dermatological Applications

    Author : Jakob Borup Thomsen; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; medical imaging; skin cancer diagnostics; optical imaging; blood flow; treatment monitoring;

    Abstract : Optical coherence tomography (OCT) is a non-invasive optical imaging technique providing approximately 10 micrometer resolution of tissue in vivo. Within ophthalmology, OCT has already proven its value and is routinely used for diagnosing retinal diseases. READ MORE

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

    Author : Simon Winter; Linda Lundström; Stephen Burns; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Clinical Studies on Dark Adaptation: with Particular Reference to Carotid Artery Disease

    Author : Ulf Havelius; Oftalmologi (Malmö); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; polycythemia; photoreceptors; phlebotomy; ocular blood flow; headache; dilation lag; dark adaptometry; dark adaptation; color Doppler imaging; carotid artery stenosis; carotid artery disease; carotid endarterectomy; pupil; pupillometry; retinal blood flow; Ophtalmology; Oftalmologi;

    Abstract : Purpose: To study dark adaptation in patients with symptomatic carotid artery disease or polycythemia before and after treatment. This necessitated determinations of pupillary changes as such may influence the findings. To determine whether changes in the retinal blood flow in light and darkness occur in healthy humans.

  7. 5. Retinal thickness measured with optical coherence tomography in patients with multiple sclerosis

    Author : Ulrika Birkeldh; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The retina offers a unique window to the brain with its unmyelinated axons that converge to the optic nerve. Optical coherence tomography (OCT) is a well-established and non-invasive imaging technique in the ophthalmology field. The retinal layers can be imaged directly, and OCT is often described as an optical biopsy of retinal tissue. READ MORE
