The Advanced Glaucoma Intervention Study (AGIS) : 7 (2000) The relationship between control of intraocular pressure and visual field deterioration. In high IOP values, measurements with the iCare tonometer do not correlate well with GAT. The iCare tonometer is a mobile alternative to GAT in a low to moderate IOP range, but our findings show a greater deviation than previously reported. The measurement with the iCare tonometer was well tolerated 100% of the patients denied any discomfort. In the higher IOP range (23вЂ“60В mmHg), however, the deviation was almost twice as large. The distribution of the differences in IOP was similar, from 7вЂ“22В mmHg. Overall, the 95% confidence interval of the differences between the two devices was в€’8.67 to 10.25В mmHg and in 62.7%, the iCare measurement was within в“В mmHg of the GAT measurements. To establish the agreement between the two devices, a Bland-Altman analysis was performed. All patients were asked about discomfort during the iCare measurement. The measurements were taken by two independent observers in a masked fashion. The study included 75 eyes of 75 patients. Furthermore, the comfort level of the iCare measurement was evaluated. The aim of this study was to compare the intraocular pressure (IOP) results measured by the iCare rebound tonometer with those obtained by the Goldmann applanation tonometer (GAT) over a wide range of IOP values.
