  2. 11. Studies into The Mechanisms of Neurodegeneration and Neuroprotection in Rd1 Mouse Retina

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

    Abstract : 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. READ MORE

  4. 12. Experimental Vitreous Substitution

    Author : Henrik Barth; Lund Oftalmologi; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 13. Optimal Use of Peripheral Vision

    Author : Karthikeyan Baskaran; Jörgen Gustafsson; Peter Unsbo; Staffan Carius; Michael Crossland; Linnéuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; off-axis refractive errors; peripheral aberrations; aberrometers; central visual field loss; preferred retinal locus; eccentric viewing; absolute central scotoma; adaptive optics; eccentric correction.; Optometry; Optometri;

    Abstract : People who lose their central vision have to rely on their peripheral vision for all visual tasks. The ability to resolve fine details in the periphery is reduced due to retinal limitations and the optical aberrations arising from the use of off-axis vision. READ MORE

  6. 14. New methods to evaluate the effect of conventional and modified crosslinking treatment for keratoconus

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

    Abstract : 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. READ MORE

  7. 15. Improved computerized perimetric threshold strategies

    Author : Boel Bengtsson; Oftalmologi (Malmö); []
    Keywords : 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;

    Abstract : 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. READ MORE
