  1. 1. Evaluation of the infrared reflection method for saccadic eye movement velocity analysis

    Författare :Frank Träisk; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Infrared reflection; Scleral search coil; Saccade; Main sequence; Eye-tracking.;

    Sammanfattning : Saccades are rapid eye movements that change the orientation of the eyes onto objects of interest. In an every day situation saccadic eye movements are used for e.g. reading, scanning objects and enviromnents. LÄS MER

    Nyckelord :Graves disease; thyroid associated ophthalmopathy; saccade; main sequence; magnetic scleral search coil; infrared reflection; radioiodine; anti-thyroid drugs; smoking;

    Sammanfattning : Thyroid associated ophthalmopathy (TAO) is the orbital manifestation of autoimmune thyroid disease that clinically affects about 30-50 % of patients with Graves disease (GD). The clinical features of TAO are in most patients mild and transient. LÄS MER

  4. 3. Characterisation of nystagmus waveforms in eye-tracker signals

    Författare :William Rosengren; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Eye tracking; Signal processing; Nystagmus;

    Sammanfattning : This thesis deals with the analysis of eye–tracker signals recorded from nystagmus patients. Nystagmus is an eye movement disorder caused by an underlying condition, and patients who suffer from nystagmus express involuntary oscillating eye move- ments. LÄS MER
