  1. 1. The Rarebit fovea test : a new measure of visual function

    Författare :Maria Nilsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Rarebit Fovea Test; Rarebit Perimetry; foveal function; fixation; diabetes; cataract; binocular summation;

    Sammanfattning : Visual acuity (VA) measurement by the use of letter charts is the most frequently used method for testing foveal function. However, since a decimal visual acuity of 1. LÄS MER

  3. 2. A Study of Some Temporal Properties of the Human Visual Evoked Potential, and Their Relation to Binocular Function

    Författare :Björn Johansson; Peter Jakobsson; Anders Sjöström; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; VEP Visual Evoked Potential ; contrast sensitivity; binocularity; latency; Fourier analysis; strabismus; amblyopia; Ophtalmology; Oftalmologi;

    Sammanfattning : As disturbed binocular functions in small children may lead to severe amblyopia it is of interest to detect it as early as possible. Most tests for binocular functions, however, demand active cooperation and may be unreliable in children up to 4-5 years of age. LÄS MER

  4. 3. Effects of eye and neck muscle proprioception on ocular motor control in normal and strabismic subjects

    Författare :Ying Han; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :strabismus; binocular function; proprioception; eye position; muscle vibration; eye muscle; neck muscle; hand pointing; accommodative vergence movement; dynamics;

    Sammanfattning : Abundant proprioceptive information originates in eye and neck muscles but their role in normal visual function is unknown. Under experimental conditions, proprioceptive activation induces illusory visual movement, whereas clinical evidence indicates that proprioceptive dysfunction causes disturbances in spatial orientation.

  5. 4. Investigations of binocularity and reading performance in healthy subjects and patients with mild traumatic brain injury

    Författare :Jan Johansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: It is known that problems with binocular vision can cause issues for reading, less well known is to what extent binocular vision improves reading performance. A key aim for this project was to estimate the contribution of binocularity in reading in healthy subjects, and in patients with mild traumatic brain injury (MTBI). LÄS MER

  7. 5. Amblyopia in children : therapy and follow-up

    Författare :Pia Agervi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Amblyopia, the leading cause of unilateral visual impairment in children, is caused by inadequate stimulation of the visual system during the sensitive periods of visual development in childhood. Cataract, anisometropia and strabismus are well-known causes of amblyopia. LÄS MER
