  1. 1. A New Model for Assessment of Change in Visual Function in Diabetes

    Författare :Karl-Johan Hellgren; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetic retinopathy; visual function; perimetry;

    Sammanfattning : The purpose of this thesis was to determine whether perimetry using a new model to interpret deterioration or improvement in the visual field can be employed to assess change in visual function over time in diabetes. Diabetic retinopathy has long been considered a microvascular disease, but it is still a matter of debate to what extent diabetes also affects retinal neurons. LÄS MER

  2. 2. Progression in Glaucoma

    Författare :Hanna Maria Öhnell; Oftalmologi (Malmö); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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. 3. Regression Analysis of Censored Data with Applications in Perimetry

    Författare :Anna Lindgren; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; censored covariate; L_1 minimization; right-censoring; Quantile regression;

    Sammanfattning : This thesis treats regression analysis when either the dependent or the independent variable is censored. We deal with quantile regression when the dependent variable is censored. LÄS MER

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

    Författare :Lada Kalaboukhova; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    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.

  5. 5. Improved computerized perimetric threshold strategies

    Författare :Boel Bengtsson; Oftalmologi (Malmö); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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;

    Sammanfattning : 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. LÄS MER
