Abstract :Purpose:To compare intraocular pressure (IOP) measurements obtained with Goldmann applanation tonometer (GAT), pneumotonometer, and Tono-pen in patients using topical antiglaucomatous medication due to primer open angle glaucoma. Patients and Methods:The medical documents of patients using topical antiglaucomatous medication due to primary open angle glaucoma were retrospectively investigated in this non-randomized case-control study. Only right eyes of 113 patients were included. The IOP measurements obtained with pneumotonometer and Tono-Pen were statistically compared with the IOP measurements obtained with GAT, and the correlations between series were investigated. Results:The mean age was 57.41 11.02 years (41 – 82 years) in 113 patients, 52 males and 61 females (p = 0.638). The mean IOP was 21.04 5.40 mmHg (12 – 46 mmHg) with GAT, 20.19 5.61 mmHg (12 – 48 mmHg) with pneumotonometer and 17.37 4.99 mmHg with tonopen (8 – 44 mmHg). The mean IOP values obtained with both pneumotonometer and tonopen were significantly lower than the mean IOP obtained with GAT (p <0.001 for both). IOP measurements obtained with both pneumotonometer (r = 0.96 and p <0.001) and tonopen (r = 0.83 and p <0.001) were significantly correlated with IOP measurements obtained with GAT. Conclusion:IOP measurements obtained with pneumotonometer and tonopen in patients using topical antiglaucomatous medication due to primer open angle glaucoma is lower and correlated with the measurements obtained with GAT.Keywords : Glaucoma, primary open angle glaucoma, Goldmann applanation tonometer, pneumotonometer, Tono-Pen
