   Sammanfattning : Aims. The aims of this thesis were threefold. Firstly, we wanted to establish the distribution of visual acuity (VA) and the prevalence of amblyopia and other ocular disorders in two population-based samples of 12-13-year-old children, one that had been vision-screened at preschool age and the other that had not.

   Sammanfattning : Aims: Papers I & II: To evaluate the consequences of changes in the criteria for referral to an eye clinic following general pre-school vision screening. According to the former criteria all 4 year old children in the Göteborg area, with visual acuity (VA) ... LÄS MER

4. 3. Ophthalmological follow-up in young adults born premature and screened for retinopathy of prematurity

   Sammanfattning : Prematurely born children have a higher risk of ophthalmological and neurodevelopmental disorders than those born at term. There is a paucity of long-term prospective follow-up studies on the visual function of prematurely born adults. LÄS MER

5. 4. Visual outcome, ocular findings, and visual processing skills after allogeneic stem cell transplantation in children

   Författare :Alba Lucia Törnquist; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Stem cell transplantation (SCT) offers a chance of cure in children with leukaemia and other life-threatening haematological, immunological, and metabolic diseases that do not respond to conventional treatment. Pre and post SCT, these children receive irradiation, and/or chemotherapy and immunosuppressive agents which like the primary disease may adversely affect the eye, the central nervous system as well as the posterior visual pathways and potentially threaten vision.

7. 5. Clinical assessment of visual function with particular emphasis on testing methods for young children

   Författare :Agneta Rydberg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :amblyopia; children; contrast sensitivity; crowding; detection acuity; linear tests; ocular disease; preferential looking; recognition acuity; resolution acuity; single tests; strabismus; visual acuity; visual impairment;

   Sammanfattning : Research during the last decades has emphasised the importance of visual stimulation during the first months of life. It is consequently of great importance to identify children with subnormal vision as early as possible in order to start treatment and habilitation. LÄS MER
