Objective: To evaluate the degree of agreement in relation to the intraocular pressure (IOP) value between the Goldmann tonometer and the iCare tonometer in a cataract surgery campaign.
Methods: Cross-sectional study. IOP was evaluated in people who attended preoperative cataract surgery in a rural hospital in Taco Pozo, province of Chaco, Argentina in August 2023. The degree of concordance between IOP values obtained with both measurement methods was evaluated by means of an Altman Bland analysis, with a paired t-test to indicate the differences between both. Results of the general population and by subpopulations were analyzed in relation to IOP (higher or lower than 21 mmHg).
Results: IOP was evaluated in 385 eyes. IOP values for the general population were (Goldmann first and then iCare) 15.6 ± 4.3 and 17.7 ± 6.0 (p<0.001); in eyes with IOP up to 21 mmHg it was 14.9 ± 2.5 and 16.8 ± 3.9 (p<0.001); in eyes with IOP > 21 mmHg it was 27.4 ± 8.6 and 31.8 ± 11.5 (0.07).
Conclusion: A good level of agreement was found between Goldmann tonometry and the iCare for eyes with IOP > 21 mmHg. The iCare is considered to be a reliable method to detect ocular hypertension in cataract campaigns.
