Abstract

Background: Glaucoma is a leading cause of irreversible blindness worldwide. Intraocular Pressure (IOP) is an important factor for glaucoma patients’ evaluation, diagnostic and management .The standard IOP measurement is Goldmann Applanation Tonometry (GAT). However, there are some limitations in some patients who need of skilled examiner, children, uncooperative patient and patients who are allergic to anesthetic eye drops or fluorescein staining. Non-contact air-puff tonometer (NCT) has been developed for IOP measurement to solve these problems. So the accuracy of NCT compare to standard GAT was studied.


Objectives: To compare intraocular pressure (IOP) measured by non-contact air-puff  tonometer and Goldmann applanation tonometer in patients with glaucoma.


Methods: An observational cross-sectional comparative study was done from 1 October to 31 December 2021 in Krabi hospital. There are 92 patients, 174 eyes from both glaucoma and glaucoma suspect groups. The IOP were measured by NCT and GAT in glaucoma outpatient clinic. The differences in IOP readings between the two techniques were evaluated.


Results: The mean IOP values of overall participants measured by NCT and GAT were 17.17 ± 5.17 and 18.72 ± 6.39 mmHg (p-value = 0.000) respectively. In the group with IOP less than 21 mmHg, the mean IOP values measured by NCT and GAT were 14.80 ± 3.13 and 15.89 ± 2.87 mmHg (p-value <0.001) and in the group with IOP greater than or equal to 21, the mean IOP values were 22.79 ± 4.72 and 25.43 ± 7.39 mmHg (p-value = 0.000) respectively


Conclusion: The mean IOP values measured by NCT was significantly lower than IOP measured by GAT in both IOP less than 21 mmHg group and IOP greater than or equal to 21 mmHg group. The examiner should consider additional IOP measurements by GAT for more accurate and reliable clinical decision-making
