    This study introduces a novel computer method for analyzing optic disc images. The technique allows for detailed topographic and relief mapping, aiding in the quantitative diagnosis of optic disc pathologies.

    Area of Science:

    • Ophthalmology
    • Medical Imaging
    • Computer Science

    Background:

    • Optic disc analysis is crucial for diagnosing various eye conditions.
    • Traditional methods may lack quantitative precision for certain pathologies.

    Purpose of the Study:

    • To present a novel computer-based method for optic disc image analysis.
    • To enable both qualitative and quantitative assessment of optic disc features.

    Main Methods:

    • Scanning television camera used to digitize black and white optic disc transparencies.
    • Image digitization up to 4,000 x 4,000 pixels with 256 gray levels.
    • Image representation as topographic contour maps or relief images based on light intensity.

    Main Results:
