Background: Intraocular pressure measurement (tonometry) has prime importance because it is the most significant risk factor for the development and progression of glaucoma, and due to the presence of numerous types of tonometers, it is important to compare between different tonometers readings [in this study Goldmann and Tono-pen (AccuPen)] Objectives: This study aims to evaluate the sensitivity, specificity and accuracy of theAccuPen tonometer in our clinical practice by comparing the measurement of intraocular pressure using this method with that using the Goldmann applanation tonometer (gold standard). Subjects and methods: A comparative study was done during the period from December 2014 to April 2015, during which the intraocular pressure for the (110) eyes of (55) Iraqi citizens (all of them attendants of the outpatient department of Ibn-Al Haitham-teaching hospital) was measured using both the Goldmann applanation tonometer and the AccuPen handheld electronic applanation tonometer. Results: The average difference between the readings of AccuPen and Goldmann tonometer’s (AccuPen minus Goldmann's readings) was 3.0 mmHg. Regarding the validity of the AccuPen test, this study found the sensitivity to be 100% and the accuracy to be 88% in comparison with the gold standard Goldmann tonometer. Conclusions: AccuPen is a good screening method for the detection of increased IOP with high sensitivity and accuracy in comparison with gold standard method (Goldmann tonometer).
