1. 16. Clinical expressions of juvenile hereditary retinal degenerations and macular dystrophies: Electrophysiological and genetic studies

   Författare :Louise Eksandh; Lund Oftalmologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oftalmologi; Ophtalmology; Rod-monochromacy; Stargardt disease; Juvenile X-linked retinoschisis; Spielmeyer-Vogt disease; Best disease; multifocal-ERG; EOG; full-field ERG; Phenotype; genotype;

   Sammanfattning : Hereditary retinal degenerations are the most frequent reason for severe visual handicap among young people in Scandinavia today. In the six papers included in this thesis the phenotypic expressions, with emphasis on the electrophysiological findings, of five different juvenile hereditary retinal degenerations are described.

3. 17. Experimental vitreoretinal surgery in the rabbit eye - electrophysiology and morphology

   Författare :Karin Gjörloff; Lund Oftalmologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oftalmologi; Ophtalmology; retinectomy; GFAP; PKC; rabbit; vitrectomy; focal laser photocoagulation; full-field electroretinography; multifocal electroretinography;

   Sammanfattning : The field of vitreoretinal surgery has expanded greatly over the last decades. A continuous refinement of surgical methods and instruments has increased the number of treatable retinal disorders. Vitrectomy, retinectomy and laser treatment are all part of the modern surgical arsenal. LÄS MER

4. 18. Electrophysiology and optical coherence tomography in acquired and hereditary retinal disorders

   Författare :Patrik Schatz; Lund Oftalmologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Retinal degeneration; multifocal ERG; Oftalmologi; Ophtalmology; OCT;

   Sammanfattning : In this thesis, retinal function in general, as well as central retinal function and structure are described in selected forms of acquired and hereditary retinal disorders, in order to improve our understanding of underlying pathogenic mechanisms. This comparison has been made possible during the last years, through the relatively recent development of multifocal ERG (mfERG) and optical coherence tomography (OCT) for the analysis of central retinal function and structure, respectively.

5. 19. Tracing local hyaluronan after ocular anterior segment trauma

   Författare :Anna Makar; Lund Oftalmologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oftalmologi; Ophtalmology; COX-2 inhibitors; radiolabeling; trauma response; aqueous humor; hyaluronan; iris;

   Sammanfattning : Hyaluronan has been found in the eye in varying amounts and at different sites. It is involved in physiological and pathological processes, though many aspects of its bio-logi-cal functions are still unclear. We have studied the role of iris tissue in hyal-uro-nan production in the anterior segment of the eye, and its changes after trauma. LÄS MER

7. 20. Retinal Transplants: Growth Differentiation Integration Organization and Survival

   Författare :Rajesh Kumar Sharma; Lund Oftalmologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; retinal degeneration; Retinal transplants; retinal development; treatment; connections; proliferation; survival; Ophtalmology; Oftalmologi;

   Sammanfattning : The goal of the study was to get a better understanding of factors controlling the growth, differen-tia-tion, integration, organization and survival of retinal transplants, with the long-term view of eventually developing retinal transplantation into a clinically useful procedure for treating degenerative retinal disorders such as retinitis pigmentosa. Embryonic day 15 rabbit retinas were transplanted into adult rabbit eyes and were allowed to survive for various times. LÄS MER
