    The Competer automatic campimeter detects substantial glaucoma visual field defects but may miss early signs and small central vision issues. Its stimulus distribution needs improvement for comprehensive eye defect detection.

    Area of Science:

    • Ophthalmology
    • Medical Technology

    Background:

    • Visual field testing is crucial for diagnosing and monitoring optic nerve disorders like glaucoma and maculopathies.
    • Automatic campimeters aim to standardize and improve the efficiency of visual field examinations.

    Purpose of the Study:

    • To evaluate the diagnostic performance of the Competer automatic campimeter in detecting glaucomatous and maculopathic visual field defects.
    • To identify the limitations of the Competer in specific visual field testing scenarios.

    Main Methods:

    • The Competer automatic campimeter was utilized to test the visual fields of 98 patients.
    • Data analysis focused on 31 patients with glaucomatous defects and 11 with (para) central defects from maculopathies.

    Main Results:

    Related Experiment Videos

    • The Competer successfully detected substantial glaucomatous visual field defects.
    • However, it may miss early glaucomatous defects and is not suitable for detecting small (para) central defects due to limited stimulus positions.
    • The device exhibits a large dynamic range and effective detection strategy, but stimulus distribution requires enhancement.

    Conclusions:

    • The Competer is effective for identifying significant glaucomatous visual field loss.
    • Its current configuration is suboptimal for detecting early-stage glaucoma and small central visual field abnormalities.
    • Improvements in stimulus positioning are recommended for more comprehensive visual field assessment.
