    Sammanfattning : Intraocular pressure (IOP) measurement is a routine procedure and a fundament in glaucoma care. Elevated IOP is the main risk factor for glaucoma, and to date, reduction of IOP is the only possible treatment.In a retrospective clinical material, the prevalence of open angle glaucoma was estimated on the west coast of Iceland.

  3. 2. Pressure sores : risk assessment and prevention

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Margareta Lindgren; Christina Lindholm; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN;

    Sammanfattning : The aims of this thesis were to study the prevalence, incidence, prevention and treatment of pressure sores, to further develop a risk assessment scale, and test the reliability and validity of this scale, to identify risk factors for pressure sore development, and to study skin blood flow in non-blanchable erythema areas as compared to undamaged skin.Criteria used for pressure sore assessment were persistent discoloration i.

  4. 3. Preventing pressure ulcers by assessment of the microcirculation in tissue exposed to pressure

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Sara Bergstrand; Margareta Lindgren; Anna-Christina Ek; Maria Engström; Lars-Göran Lindberg; Fredrik Huss; [2014]

    Sammanfattning : The overall aim of this thesis was to combine optical methods into a system with the ability to simultaneously measure blood flow changes at different tissue depths. The goal of such a system was to reveal vascular mechanisms relevant to pressure ulcer etiology under clinically relevant conditions and in relation to the evaluation of pressure-redistribution support surfaces.

    Sammanfattning : Background: Pressure ulcers are related to reduced quality of life for patients and high costs for health care. Guidelines for pressure ulcer prevention have been available for many years but the problem remains. LÄS MER

  7. 5. Studies on sitting pressure and buttock microcirculation : aiming at developing an alarm in the prevention of pressure ulcers in patients with spinal cord injuries

    Detta är en avhandling från Institutionen för biomedicin och kirurgi

    Sammanfattning : Pressure ulcers in patients with spinal cord injuries are a major problem, the prevalence in this group being reported as high as 20 – 30 percent. Most pressure ulcers develop around the pelvic girdle, and the key-contributing factor in the development of pressure ulcers is ischaemia due to longstanding pressure. LÄS MER
