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

    Detta är en avhandling från Department of Ophthalmology, Lund University

    Författare :Kjell Gunnar Gundersen; Lund University.; Lunds universitet.; [1999]
    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

  2. 2. Analysis of Angiographies in Human Healthy Eyes and in Open-angle Glaucoma Retinal Mean Transit Time and Optic Nerve Head Circulation

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Gunilla Bjärnhall; Uppsala universitet.; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE Physiology and pharmacology Ophtalmology; MEDICIN Fysiologi och farmakologi Oftalmologi;

    Sammanfattning : Purpose of the studies was to develop a more robust technique to determine retinal mean transit time in healthy and in glaucoma eyes and to evaluate the circulation of the optic nerve head in glaucoma patients.The retinal mean transit time impulse-response method was evaluated in human healthy eyes and normal values and reproducibility were tested.

  3. 3. Ophthalmologic characteristics andneuropediatric findings. With special emphasis on children adopted from eastern Europe

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Sammanfattning : Aim: To evaluate and relate visual function and ocular features to neuropediatric findings in a population-based group of children adopted from eastern Europe (Papers I-III) and in children with attentiondeficit hyperactivity disorder (AD/HD), with and without treatment with stimulants (Paper IV).Methods: 99 children born 1990 1995 in eastern Europe and adopted to western Sweden during1993 1997 were invited to participate.

  4. 4. Morphometry of the Optic Nerve Head as a Diagnostic Tool for Glaucoma

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Camilla Sandberg Melin; Uppsala universitet.; Uppsala universitet.; [2019]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; optic nerve head; ONH; nerve fibers; glaucoma; optical coherence tomography; OCT; Pigment epithelium central limit-inner limit of the retina minimal distance; PIMD; PIMD-2π; Segmental PIMD-2π; confocal scanning laser tomography; HRT; NRA; variation; variability; variance; loss rate; follow-up.;

    Sammanfattning : Glaucoma is a chronic optic nerve head (ONH) disease. Gradual retinal ganglion cell and nerve fiber loss lead to morphological ONH change and visual field defects. Initial loss is often focal. Rate of progression and life expectancy guide treatment. LÄS MER

  5. 5. On the identification of visual defects in children in general and prematurely born children in particular

    Detta är en avhandling från Göteborg

    Författare :Anna-Lena Hård; Göteborgs universitet.; Gothenburg University.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; preschool vision screening; referral criteria; children; vision; preterm; cerebral visual impairment; visual perception; ocular fundus morphology;

    Sammanfattning : Aims: Papers I & II: To evaluate the consequences of changes in the criteria for referral to an eye clinic following general pre-school vision screening. According to the former criteria all 4 year old children in the Göteborg area, with visual acuity (VA) <0.8 in either eye, were referred. Since 1992, children with slightly reduced vision (0. LÄS MER
