Resumo: | The reproducibility of measurements of intraocular pressure (IOP) at the same points of the 24-hour daily tension curve (DTC) with three replications was evaluated. Thirtythree untreated subjects with glaucoma and suspected glaucoma were studied. All participants underwent three 24-hour DTCs. Briefly, participants were hospitalized and IOP measurements obtained at 9:00 AM, noon, 3:00 PM, 6:00 PM, 9:00 PM, midnight and 6:00 AM using a Goldmann applanation tonometer. The 6:00 AM measurement was also obtained at bedside with a handheld Perkins tonometer prior to Goldmann tonometry. A second 24-hour DTC was performed 1 to 3 weeks after the first, and a third and final curve was obtained 1 to 3 weeks after the second. Reproducibility of measurements at each time point of the 24-hour DTC was assessed by means of the intraclass correlation coefficient (ICC) and Bland-Altman plots. A 3-mmHg difference in IOP was defined as the limit of agreement for Bland- Altman plots. ICCs ranged from 0.736 to 0.917 at different time points, with the majority exceeding 0.800. The percentage of points within the 3-mmHg limit of agreement on Bland-Altman plots ranged from 72.7% to 97.0%, exceeding 80% in most cases. In conclusion, in patients with glaucoma or suspected glaucoma, IOP measurements obtained at each time point of the 24-hour DTC showed good or excellent reproducibility across the three curves performed |
