Intraocular pressure tonometry.

I A Abrahamson

    American Family Physician
    |June 1, 1978

    Summary
    This summary is machine-generated.

    Family physicians should measure intraocular pressure to detect chronic open-angle glaucoma early. Tactile tension is insufficient; use the Schiøtz tonometer for accurate readings, with further tests needed if pressure exceeds 21 mm. Hg.

    Area of Science:

    • Ophthalmology
    • Primary Care Medicine

    Background:

    • Early detection of chronic open-angle glaucoma is crucial for preventing vision loss.
    • Routine screening in primary care settings can facilitate early diagnosis.
    • Ocular hypertension is a significant risk factor for glaucoma development.

    Purpose of the Study:

    • To emphasize the importance of intraocular pressure measurement in routine family physician examinations.
    • To highlight the limitations of tactile tension assessment for glaucoma screening.
    • To recommend appropriate tonometry methods for general practice.

    Main Methods:

    • Review of diagnostic methods for glaucoma screening.
    • Focus on the Schiøtz tonometer as a suitable instrument for general use.
    • Emphasis on proper technique for accurate intraocular pressure measurement.

    Main Results:

    • Tactile estimation of intraocular pressure is unreliable for glaucoma diagnosis.
    • The Schiøtz tonometer provides a more objective measurement.
    • Intraocular pressure readings above 21 mm. Hg warrant further investigation.

    Conclusions:

    • Intraocular pressure measurement should be a standard part of family physician examinations.
    • Early detection of glaucoma through tonometry can preserve vision.
    • Accurate technique and appropriate instrumentation are essential for effective glaucoma screening.
