“…As reported previously [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ], the IOPs measured using the three devices were correlated with each other, and all were affected by the CCT ( Table 2 ). A significant positive association between the CCT and IOP NCT-GAT and IOP RBT-GAT ( Table 2 ) suggested a larger effect of the CCT on the IOPs obtained with NCT or RBT than with GAT, as reported previously [ 6 , 15 ].…”

“…Subject age and the detected difference between GAT and RBT readings in previous and current studies are summarized in Table 4 . Including the current study, some studies have reported minus IOP RBT-GAT values [ 10 , 12 , 13 , 14 ], while others have reported plus IOP RBT-GAT values [ 4 , 5 , 6 , 7 , 8 , 11 , 15 , 16 ]; this discrepancy is not fully explained by the difference in the CCT. Scatterplots of the subjects’ ages and IOP RBT-GAT from previous studies ( Table 4 and Figure 1 ) clearly suggest the roles of age and IOP RBT-GAT .…”

“…Previously, many studies have reported excellent correlations between IOP readings and GAT and NCT or RBT IOPs, although the IOP values themselves varied among the tonometers [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ]. Most previous studies have assessed the CCT as a surrogate for explaining the measurement difference among tonometers [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ]; however, other parameters that possibly affect IOP differences among tonometers have not been studied extensively.…”

This study aimed to compare intraocular pressures (IOP) using different tonometers, Goldmann applanation (IOPGAT), non-contact (IOPNCT), and rebound (IOPRBT), and to assess the effects of aging and central corneal thickness (CCT) on the measurements. The IOPGAT, IOPNCT, IOPRBT, mean patient age (65.1 ± 16.2 years), and CCT (521.7 ± 39.2 µm) were collected retrospectively from 1054 eyes. The differences among IOPs were compared by the paired t-test. Possible correlations between devices, age, and CCT were assessed by linear regression analyses. The effects of age and CCT on the IOP reading were assessed by mixed-effects regression models. The IOPGAT values were 2.4 and 1.4 mmHg higher than IOPNCT and IOPRBT, respectively; the IOPNCT was 1.0 mmHg lower than IOPRBT (p < 0.0001 for all comparisons). The IOPs measured by each tonometer were highly correlated with each other (r = 0.81–0.90, t = 45.2–65.5). The linear regression analyses showed that age was negatively correlated with IOPNCT (r = −0.12, t = −4.0) and IOPRBT (r = −0.14, t = −4.5) but not IOPGAT (r = 0.00, t = −0.2); the CCT was positively correlated with IOPGAT (r = 0.13, t = 4.3), IOPNCT (r = 0.29, t = 9.8), and IOPRBT (r = 0.22, t = 7.2). The mixed-effect regression models showed significant negative correlations between age and IOPNCT (t = −2.6) and IOPRBT (t = −3.4), no correlation between age and IOPGAT (t = 0.2), and a significant positive correlation between CCT and the tonometers (t = 3.4–7.3). No differences between IOPGAT and IOPRBT were seen at the age of 38.8 years. CCT affects IOPs from all tonometers; age affects IOPNCT and IOPRBT in different degrees. IOPRBT tended to be higher than IOPGAT in young subjects, but this stabilized in middle age and became higher in older subjects.

Background: Intraocular pressure (IOP) is an eye parameter of fundamental importance for the diagnosis of several eye conditions, including glaucoma, ocular hypertension, uveitis and trauma. This study aimed to evaluate the difference between IOP measurements taken by a Goldmann Applanation Tonometer and those taken by -care Tonometer. Methods: this cross sectional study comprised 180 eyes from 90 subjects males and females with age ranged between 16:62 years old. All patients in this study underwent Full history and full ophthalmic examination and assessment of visual acuity: Uncorrected visual acuity (U.C.V.A.), best corrected visual acuity (B.C.V.A.), Refraction using NIDEK Auto-Refractometer-Keratometer, anterior segment examination by slit-lamp biomicroscopy, Intraocular pressure (IOP) measurement using Goldman Applanation Tonometer (Haag -Streit At 900˚ Swiss Made) and Handheld non-contact icare IC100 , fundus examination (including posterior vitreous, disc and macular examination). Results: There were highly significant differences between IOP measurements taken by I care and IOP measurements taken by Goldmann Applanation Tonometer (p <0.001); the mean of IOP measured by I care (15.73±3.58) was significantly lower than the mean IOP measured by Goldmann (17.35±1.99), Conclusion: the I-care tonometer almost constantly produces IOP measurements lower than those of the gold standard Goldmann Applanation Tonometry.
