This study investigated the agreement between a new rebound tonometer, IC200, and IcarePRO and Goldmann applanation tonometry (GAT). This was a prospective cross-sectional study. We measured the intraocular pressure (IOP) in 145 eyes of 145 glaucoma patients in the sitting position using GAT, IcarePRO, and IC200. IcarePRO and IC200 measurements were also obtained in the supine position. IC200 measurement was performed using two modes: single six (IC200-single) and automatic (IC200-continuous) six-measurements mode. All tonometers provided high reproducibility in both positions (all intraclass correlation coefficients > 0.90), although it was highest with GAT, followed by IC200-continuous and IC200-single and then IcarePRO. In the sitting position, the mean (± SD) IOPs of GAT, IcarePRO, IC200-single, and IC200-continuous were 14.5 ± 2.9 mmHg, 13.3 ± 3.2 mmHg, 11.6 ± 3.2 mmHg, and 11.5 ± 3.2 mmHg, respectively. IOPs measured with IcarePRO or IC200 were significantly lower than those with GAT, particularly in patients with low IOP. IOPs measured with all tonometers were significantly elevated in the supine position as compared with the sitting position, but this difference was significantly greater with IC200-single and IC200-continuous compared with IcarePRO. IOP elevation was significant in eyes without bleb versus those with bleb, but this finding was not observed when IOP was measured with IcarePRO. The IOPs of the single and continuous modes of IC200 were interchangeable in both positions. GAT, IcarePRO, and IC200 had sufficiently high reproducibility, but measurements with IcarePRO may not be accurate in the supine position. Elevation of IOP in the supine position, especially in eyes with bleb, was more sensitively captured with IC200 than with IcarePRO. Japan Clinical Trials Register, No. UMIN000039982 .

与 IcarePRO 和 Goldmann 压平眼压计相比，iCare IC200 回弹眼压计在青光眼患者中的评估

本研究调查了新型回弹眼压计 IC200 与 IcarePRO 和 Goldmann 压平眼压计 (GAT) 之间的一致性。这是一项前瞻性横断面研究。我们使用 GAT、IcarePRO 和 IC200 测量了 145 名青光眼患者坐位时的 145 只眼的眼内压 (IOP)。IcarePRO 和 IC200 测量值也在仰卧位获得。IC200 测量使用两种模式进行：单六（IC200-single）和自动（IC200-连续）六测量模式。所有眼压计在两个位置都提供了高重现性（所有组内相关系数 > 0.90），尽管 GAT 最高，其次是 IC200-连续和 IC200-单次，然后是 IcarePRO。在坐姿下，GAT、IcarePRO、IC200-single 和 IC200-continuous 的平均 (± SD) IOP 为 14.5 ± 2.9 mmHg，13。分别为 3 ± 3.2 mmHg、11.6 ± 3.2 mmHg 和 11.5 ± 3.2 mmHg。使用 IcarePRO 或 IC200 测量的 IOP 显着低于使用 GAT 测量的 IOP，尤其是在低 IOP 患者中。与坐姿相比，仰卧位使用所有眼压计测量的 IOP 显着升高，但与 IcarePRO 相比，IC200-single 和 IC200-continuous 的这种差异显着更大。与有水泡的眼睛相比，没有水泡的眼睛的 IOP 升高显着，但是当使用 IcarePRO 测量 IOP 时没有观察到这一发现。IC200 的单模式和连续模式的 IOP 可在两个位置互换。GAT、IcarePRO 和 IC200 具有足够高的重现性，但使用 IcarePRO 进行的测量在仰卧位可能不准确。仰卧位眼压升高，特别是在有水泡的眼睛中，用 IC200 比用 IcarePRO 更灵敏地捕获。日本临床试验注册，编号 UMIN000039982。
