摘　　要：目的分析iCare回弹式眼压计在测量角膜不同位置、不同角度时对眼压的影响。方法应用iCare回弹眼压计测量108名志愿者右眼眼压，探针垂直于角膜面测量角膜中央区域、距角膜缘2mm的鼻侧及颞侧区域眼压，探针倾斜10～20。测量角膜中央区域眼压。测量结果使用配对t检验及Pearson相关分析，比较不同位置、不同角度测量眼压结果的相关性。结果探针垂直测量角膜中央、距角膜缘2mm的鼻侧及颞侧区域（沿0—180°子午线）眼压分别为（16．38894-5．30532），（16．37044-5．47994），（16．4352±5．71974）mmHg，角膜中央眼压和水平子午线的鼻侧（r2=0．910，P〈0．05）、颞侧（r^2=0．878，P〈0．05）眼压有很好的相关性。探针倾斜10—20。角膜中央的眼压为（16．4722±5．33978）himHg，眼压结果均与探针垂直于角膜中央眼压具有很好的相关性（r^2=0．853，P〈0．05）。结论iCare回弹式眼压计既可以通过角膜中央区域又可通过角膜周边区域获得可靠的眼压，而且无论探针是垂直与倾斜。Objective To analyze the effect of iCare rebound tnnometer in different position, different angle measuring on intraocular pressure. Methods Intraocular pressure was measured using the iCare rebound tonometer on the right eyes of 108 subjects in various conditions as follows： first, in an upright position toward the center of the cornea with the probe perpendicular to the corneal plane ; then, at 2 mm from the limbus in the nasal and temporal regions with the probe perpendicular to the corneal plane or along the visual axis; and lastly, with the angled probe touching the central cornea at angles of 10-20°. Paired t-test was used to assess the agreement between the three methods. Pearson＇s correlation coefficient was used for correlation analysis. Results When the probe was vertical, angle measure central corneal limbal 2 mm nasal and temporal region （0-180° along Meridian）, IOP respectively was （ 16. 388 9 ± 5. 305 32）, （ 16.370 4 ± 5. 479 94）, （ 16.435 2 ±5. 719 74）mm Hg, and good correlation was found between intraocular pressure and central cornea intraocular pressure and horizontal meridian nasal （r2 = 0. 910, P 〈 0.05 ）, temporal （r2 = 0. 878, P 〈 0. 05 ）. Probe tilt of 10 - 20~, central cornea intraocular pressure IOP results was （ 16.472 2 ± 5. 339 78） mm Hg, and relevance was found between IOP results and central cornea intraocular pressure with vertical probe （ r2 = 0. 853, P 〈 0. 05 ）. Conclusions iCare tonometer is reliable measurement of intraocular pressure not only through the central region of the cornea but also through corneal peripheral region, no matter whether the probe is vertical or inclined.
