    This study details an eye movement analysis method for clinical diagnosis. The system uses electro-oculography to record saccades, enabling precise measurement of peak velocity and amplitude for diagnostic insights.

    Area of Science:

    • Ophthalmology
    • Neuroscience
    • Biomedical Engineering

    Background:

    • Saccadic eye movements are crucial indicators in neurological and ophthalmological assessments.
    • Accurate analysis of saccades aids in diagnosing various clinical conditions.

    Purpose of the Study:

    • To present a novel method for analyzing saccadic eye movements.
    • To detail the technical implementation of saccade detection and parameter computation.

    Main Methods:

    • Saccades induced via a microcomputer-controlled TV stimulator.
    • Eye movements recorded using electro-oculography.
    • Analysis algorithm based on eye position velocity profiles to detect saccades and compute peak velocity and amplitude.

    Main Results:
