2. 1. Electrophysiology and optical coherence tomography in acquired and hereditary retinal disorders

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

   Abstract : 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.

4. 2. Diabetic retinopathy in type 1 diabetes mellitus. A study on medical risk indicators and treatment outcome

   Author : Monica Lövestam Adrian; Lund Oftalmologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ophtalmology; treatment outcome; risk-indicators; Type 1 diabetes; sight-threatening retinopathy; Oftalmologi;

   Abstract : Diabetic retinopathy is a common complication to diabetes mellitus and is still a major cause of impaired vision in the Western world. The aim of the present study was to identify medical risk factors influencing the development and progression of retinopathy in type 1 diabetic patients, and to investigate the effects of laser treatment on visual acuity and glare.

5. 3. Effect of Drugs on Rabbit Retina

   Author : Anna Cardiakidis Myers; Lund Oftalmologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Drug toxicity; electroretinography; histopathology; intravitreal injection; rifabutin; anti-VEGF; triamcinolone; benzyl alcohol; anti-TNF-alpha; adalimumab;

   Abstract : The adverse effects of drugs in the eye are not easily detected, and the underlying pathogenesis not fully understood. The effects of four different kinds of drugs have been investigated in the rabbit eye, using electroretinography, ocular examination and histochemical methods. READ MORE

6. 4. Myopia control and peripheral vision

   Author : Petros Papadogiannis; Linda Lundström; Peter Unsbo; Nicola Logan; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; myopia; peripheral vision; psychophysics;

   Abstract : The rapid rise in myopia prevalence has caused an urgent need for effectivemyopia control interventions. This thesis investigates the role of theperipheral optics of the human eye in myopia progression. It was initiallybelieved that the axial elongation of the myopic eye is caused only by thedefocus signals presented to the central retina. READ MORE

7. 5. Retinal ganglion cell examination with Optical Coherence Tomography reflects physiological and pathological changes in the eye and the brain

   Author : Abbas Al-Hawasi; Neil Lagali; Yumin Link; Per Fagerholm; Per Söderberg; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Retinal ganglion cell; Retinal nerve fiber layer; Optical Coherence Tomography;

   Abstract : The retinal ganglion cell is situated in the inner retina and its axons, composing the retinal nerve fiber layer (RNFL), leave the eye to form the optic nerve. These cells develop embryologically from the forebrain and later during development re-establish connections with different parts of the brain serving different purposes. READ MORE
