  2. 36. Investigations or perimetry and gaze-stability in healthy and deceased retina

    Author : Fredrik Källmark; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Microperimetry; fixation gaze pattern; scanning laser ophthalmoscope; visual field; scotoma; eclipse retinopathy.;

    Abstract : Our visual world is composed of images of colours, textures, edges and contrasts. In addition, these images may be moving or flickering. The goal of visual testing is to quantify these functions. READ MORE

  4. 37. Ophthalmological aspects of prematurity

    Author : Gerd Holmström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Prematmity - retinopathy of prematmity - incidence - cryotherapy refractive enors - visual impairment - strabismus - cerebral lesions - matemalrisk factorsneonatallisk factors;

    Abstract : In a prospective, population-based study of a weIl defined geographical area in Sweden, an ROP incidence of 40.4% was found among 260 prematurely born infants with a birth weight of 1500 grams or less. Cryotherapy was performed in 10.8% of the infants. READ MORE

  5. 38. Structural and functional alterations in the rat retina after long term exposure to two n-hexane metabolites

    Author : Birgitta Bäckström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : n-Hexane; 2; 5-hexanedione; 2; 5-hexanediol; immunohistochemical techniques; neurotoxicity; retinopathy; photoreceptors; light energy; electrophysiology; pupil;

    Abstract : Exposure to the two n-hexane metabolites, 2,5-hexanedione (2,5-HD) and 2,5-hexanediol (2,5-HDol) causes swellings in the distal part of long nerve axons. This phenomenon, centralperipheral distal axonopathy, was studied using an indirect immuno-peroxidase method with monoclonal antibodies to neurofilament protein. READ MORE

  6. 39. Insulin treatment of elderly type 2 diabetic patients

    Author : Jonas Tovi; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Type 2 diabetes; elderly; insulin treatment; costs; ambulatory blood pressure; monitoring; well-being; symptoms; polyneuropathy; IGFBP-1 IGF-I; retinopathy;

    Abstract : In this study, the effect of improved metabolic control through insulin treatment was investigated in elderly patients with type 2 diabetes with secondary failure of oral treatment. Forty, consecutive, elderly patients (mean age 75.3 (5.9) (mean and SD), range 67-86 years) were studied. READ MORE

  7. 40. Visual dysfunction and ocular signs associated with periventricular leukomalacia in children born preterm
