Abstrakt: Objective: To compare the intraocular pressure (IOP) values acquired from the non-contact tonometers and a Goldmann applanation tonometer in glaucoma patients. Materials and Methods: The present study included 300 eyes from 150 participants that attended the glaucoma outpatient clinic. The IOP was measured using both non-contact tonometry (NCT) and Goldmann applanation tonometry (GAT). The differences in IOP readings between the two techniques were evaluated. Results: The mean IOP as measured by NCT was 16.26±6.95 mmHg, when that of measured by GAT was 16.11±8.43 mmHg. The mean difference between the two techniques of measurement was 0.147±3.01 mmHg. The values acquired from NCT were slightly higher than those acquired by GAT in 49% of patients, and this difference was more distinct when the IOP as measured by GAT more than 21 mmHg. Conclusion: There was no statistically significant correlation in the measurement of IOP between non-contact and GAT tonometers. NCT is a proper method for mass screenings of IOP even if the IOP measurement by NCT is slightly higher than by GAT. [ABSTRACT FROM AUTHOR]
