    Area of Science:

    • Ophthalmology
    • Medical Technology

    Background:

    • Glaucoma diagnosis relies on accurate visual field testing.
    • Manual perimetry can be time-consuming and subjective.

    Purpose of the Study:

    • To evaluate the clinical utility of the COMPETER automatic perimeter's new profile testing mode.
    • To compare its performance against manual profile perimetry.

    Main Methods:

    • 110 patients (glaucoma, suspected glaucoma, normal) underwent both manual and COMPETER automatic perimetry.
    • One meridian was tested per patient.

    Main Results:

    • The COMPETER accurately identified all manually detected glaucomatous defects.
    • It detected 2 (4%) additional abnormalities missed by initial manual testing.
  • Specificity was 91%, with 5 (9%) false positives.

    • Conclusions:

    • The COMPETER automatic perimeter is accurate and sensitive for detecting visual field defects.
    • It offers a time-saving and clinically useful alternative to manual perimetry.
