  1. 1. Progression in Glaucoma

    Författare :Hanna Maria Öhnell; Oftalmologi (Malmö); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glaucoma; visual fields; perimetry; diagnosis; progression; Optical Coherence Tomography OCT ; optic disc photography;

    Sammanfattning : The treatment of glaucoma is focused on reducing the intraocular pressure to a level at which progression is impeded. A diagnosis of glaucoma is not considered certain until progression is confirmed, and thus detecting progression is a central aspect in both the diagnosing and the monitoring of glaucoma patients.

  3. 2. Glaucoma Characteristics and Risk Factors - Results from Malmö Eye Survey

    Författare :Kirsti Grødum; Oftalmologi (Malmö); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vascular disease; Ophtalmology; Oftalmologi; myopia; optic disc hemorrhages; mortality; refraction; glaucoma; population screening;

    Sammanfattning : This thesis is based on data from a large glaucoma screening, comprising 32, 918 elderly citizens of Malmö and data from retrospective analysis of glaucoma patients’ charts from the Eye Department of Malmö University Hospital. The definition of glaucoma was based on reproducible visual field defects and/or glaucomatous optic nerve head damage in both groups. LÄS MER

  4. 3. Computerised Three-Dimensional Analysis of Optic Nerve Head Topography in Normal and Glaucomatous Eyes

    Författare :Kjell Gunnar Gundersen; Oftalmologi (Malmö); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ranked segment distribution; minimal rim width; sector analysis; neuroretinal rim; global parameters; localised changes; computerised analysis; raster tomography; Optic nerve head topography; scanning laser tomography; Ophtalmology; Oftalmologi;

    Sammanfattning : Evaluation of the optic nerve head topography is one of the most important methods to diagnose and monitor patients with glaucoma. Until recently, optic nerve head topography has most often been judged by either ophthalmoscopy or from optic disc photographs. LÄS MER

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

    Författare :Lena Jacobson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. Diagnosing and monitoring open-angle glaucoma. Pupillometry and other novel techniques

    Författare :Lada Kalaboukhova; Göteborgs universitet; []
    Nyckelord :open-angle glaucoma; relative afferent pupillary defect; pupillometer; visual field; Frequency Doubling Technology Perimetry; High-pass Resolution Perimetry; Heidelberg Retina Tomography;

    Sammanfattning : Aim:To investigate the ability of a custom-built pupillometer and other novel diagnostic instruments to detect and monitor optic nerve damage in glaucoma.Methods:In the first two studies we investigated pupillary reactions to light in patients with glaucoma and in healthy persons using a custom-built pupillometer.
