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.

BACKGROUND፡ The aim of this study was to determine whether Central Corneal Thickness (CCT) is associated with intraocular pressure measurement (IOP) with a Non-contact tonometer and the Goldmann applanation tonometer in glaucoma patients.MATERIALS AND METHODS: The study involved two hundred and thirty-two eyes of clinically diagnosed glaucoma patients receiving care at a referral facility. IOP measurements were obtained using both the Non-Contact Tonometer (NCT) and Goldmann Applanation Tonometer (GAT). The association between age, ethnicity, and CCT, as well as CCT on the measures of NCT and GAT, were analyzed.RESULTS: There were 64(55.2%) males and 52 (44.8%) females and their ages ranged from 18 to 85 years (mean age = 47.72; SD ±15.75 years). There was a weak positive correlation between the CCT and NCT findings in the right eye (r = 0.19, n = 116, p < 0.05) and in the left eye (r = 0.25, n = 116, p < 0.05). However, there was no correlation between CCT and GAT measurements. Age had a significant correlation with CCT while gender and ethnicity had no significant correlation.CONCLUSION: The study found a significant association between CCT and NCT. However, there was no significant association between CCT and GAT. CCT had an association with age but independent of gender and ethnicity since there was no significant relationship between these variables.
