1. 1. rd1 Photoreceptor Degeneration: Photoreceptor Rescue and Role of Metalloproteases in Retinal Degeneration

   Författare :Poonam Ahuja Jensen; Allmänmedicin och samhällsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oftalmologi; Ophtalmology; retinal degeneration; Survival factors; metalloproteases;

   Sammanfattning : The thesis is focused on an attempt to delay photoreceptor cell death in the rd1 mouse using Lens Epithelium Derived Growth Factor (LEDGF), Glutathione S-Transferase mu (GST-?? and Glutathione S-Transferase alpha (GST-?? in an organ culture paradigm as well as the role of metalloproteases (MMPs) and their tissue inhibitors in photoreceptor degeneration (TIMPs). The rd1 mouse model displays a retina degeneration which starts around day 10 with rod photoreceptor cell death. LÄS MER

3. 2. Retinopathy of Prematurity in Infants Born Before 27 Weeks of Gestation : A National Population-based Study in Sweden During 2004-2007

   Författare :Dordi Austeng; Gerd E. Holmström; Karin B.M. Källen; Uwe W. Ewald; Olav Haugen; Uppsala universitet; []
   Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Retinopathy of prematurity; extremely preterm; population-based; epidemiology; treatment; natural history; screening; Ophtalmiatrics; Oftalmiatrik; Ophtalmology; Oftalmiatrik; Pediatrics; Pediatrik; Epidemiology; Epidemiologi;

   Sammanfattning : Background: Improved neonatal care has resulted in an increasing population of surviving infants. Neonatal morbidity in preterm infants is, however, high, and retinopathy of prematurity (ROP) is one of the major neonatal morbidities. LÄS MER

4. 3. Studies into The Mechanisms of Neurodegeneration and Neuroprotection in Rd1 Mouse Retina

   Författare :Seifollah Azadi; Lund Oftalmologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; signaling pathway ; Ophtalmology; neurotrophic factors ; Oftalmologi; retina degeneration ;

   Sammanfattning : Retinitis Pigmentosa (RP) is a group of uncured retinal diseases with the world wide incidence of about 1/3500. In spite of the huge efforts in past years, the mechanisms underlying this type of hereditary blindness has not been elucidated and nor any effective treatment available. LÄS MER

5. 4. New methods to evaluate the effect of conventional and modified crosslinking treatment for keratoconus

   Författare :Jeannette Beckman Rehnman; Christina Lindén; Anders Behndig; Per Hallberg; Jesper Hjortdal; Umeå universitet; []
   Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Keratoconus; crosslinking; light scattering; densitometry; keratometry; hysteresis; intraocular pressure; oftalmiatrik; Ophtalmology;

   Sammanfattning : Background: Today corneal crosslinking with ultraviolet-A photoactivation of riboflavin is an established method to halt the progression of keratoconus. In some cases, when the refractive errors are large and the visual acuity is low, conventional corneal crosslinking may not be sufficient. LÄS MER

7. 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
