Schiötz tonometers are still used widely for routine tonometry and glaucoma screening. Appreciation of the inaccuracy of impression tonometry has led to a general agreement that Schiötz tonometry should be supplemented by applanation tonometry. In a material of paired Schiötz and Goldmann measurements we found that about every fifth individual with an applanation pressure of over 20.5 mmHg would have been missed even if all persons with Schiötz readings lower than 7.0/7.5 were applanated. Further extension of Goldmann tonometry to patients with still higher Schiötz readings was found to be unwarranted. We concluded that the usefulness of Schiötz tonometry for glaucoma screening should be doubted.
