    Abstract:
    BACKGROUND: Guidelines for glaucoma screening by the primary care physician have not been firmly established. Despite its limitations as a screening test, intraocular pressure measurement by tonometry remains the mainstay of glaucoma monitoring but is not widely used in the primary care setting. The purpose of this study was to compare the effectiveness of noncontact tonometry using the Pulsair instrument with that of conventional tonometry using the Goldmann applanation tonometer as a screening tool for glaucoma. METHODS: Intraocular pressure was measured by non-contact and Goldmann applanation tonometry in both eyes of 50 volunteers who enrolled in a glaucoma screening program at a primary care clinic. RESULTS: Noncontact tonometry correctly identified over 90% of the patients with intraocular pressures greater than 22 mm Hg. CONCLUSIONS: Noncontact tonometry is an easy, practical, and well-tolerated method of intraocular pressure measurement. When combined with direct ophthalmoscopy, noncontact tonometry can easily be used in routine primary care health examinations to detect glaucoma.
