A tonometry study comparing Tono-Pen with Goldmann applanation tonometry in a general practice setting revealed four cases of ocular hypertension in 132 patients. Two of the 4 patients required further ophthalmological care after referral. None of these patients, but 4 patients with no ocular hypertension, would have been referred for follow-up if referral had been made on the basis of the single reading made by the general practitioner. Tonometry readings are subject to considerable random variation, and the implications for a cut-off policy in general practice is discussed. Associations between ocular hypertension and known risk factors are weak and offer limited help in selecting asymptomatic patients for measurement. Systematic screening should not be a routine. The cut-off point should be kept low to avoid false reassurance of glaucoma patients, possibly as low as 17 mmHg. Multiple measurements may limit the number of referrals if the readings remain low.
一项在普通医疗环境中比较眼压计与Goldmann压平眼压计的眼压测量研究显示，132名患者中有4例高眼压。这4名患者中有2名在转诊后需要进一步的眼科护理。如果根据全科医生的单次读数进行转诊，这些患者中没有一人会被转诊进行随访，但有4名无高眼压的患者会被转诊。眼压测量读数存在相当大的随机变化，并讨论了其对普通医疗中临界值政策的影响。高眼压与已知风险因素之间的关联较弱，在选择无症状患者进行测量方面帮助有限。系统筛查不应成为常规。临界值应保持较低，以避免对青光眼患者的错误保证，可能低至17 mmHg。如果读数仍然较低，多次测量可能会减少转诊人数。
