1. 1. Comparing retinal function and structure in diabetic maculopathy and retinal detachment with ff-ERG and a combination of mfERG and OCT

   Författare :Kristina Holm; Lund Oftalmologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mfERG; OCT; ff-ERG; diabetes; macular edema; retinal detachment; scleral buckling; retinectomy;

   Sammanfattning : Diabetic maculopathy and retinal detachment, especially involving macula, are potentially sight-threatening conditions. Previous evaluations of retinal function, and treatment of these conditions have been subjective methods depending on the examiner or the collaboration with the examined patient. LÄS MER

3. 2. Photoreceptors in experimental retinal cell transplants

   Författare :Bengt Juliusson; Lund Oftalmologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ophtalmology; immunohistochemistry; mice; rabbits; rats; interphotoreceptor matrix; retinal pigment epithelium; photoreceptors; Retina; transplantation; Oftalmologi;

   Sammanfattning : The main objective of this thesis was to investigate the fate of photoreceptor cells when using different strategies for retinal cell transplantation. Comparing transplantation of fragments of embryonic retina with cell suspensions of the same tissue we found that transplantation of fragments of embryonic retina result in mature transplants with a higher degree of cellular organization than transplantation of cell suspensions of embryonic retina.

4. 3. Experimental Vitreous Substitution

   Författare :Henrik Barth; Lund Oftalmologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Retinal Detachment; Vitreous Body : surgery; Retina cytology metabolism surgery; Retina: Function; Retina: Inflammation; Retinal Detachment; Vitreous Body : surgery; Vitreous substitute; Vitrectomy;

   Sammanfattning : Blindness and visual disability are common following vitreoretinal pathologies such as open globe injury, proliferative diabetic retinopathy, and rhegmatogenous retinal detachment (RRD). These conditions often necessitate surgical intervention using vitrectomy with a tamponading vitreous substitute. LÄS MER

5. 4. On Complications to Cataract Surgery

   Författare :Gunnar Jakobsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cataract surgery; pseudophakia; capsular rupture; retinal detachment; IOL dislocation; glaucoma; vitreous; immune mediators; immunoassay; cytokines;

   Sammanfattning : Cataract surgery, meaning exchange of the opaque lens in the eye with an artificial lens, is nowadays one of the most successful surgical procedures ever known. It is also the most frequent surgery performed in the Western world. In Sweden alone, more than 100,000 cataract operations are performed annually. LÄS MER

7. 5. 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.
