Ophthalmic parameters can be measured with different techniques and devices. Our aim was to measure anterior segment parameters using 2 optical devices and to compare the data to ultrasonic technique.
Axial length (AL) was measured with IOLMaster; anterior chamber depth (ACD) was determined using IOLMaster, Visante® optical coherence tomography (OCT), and Pentacam® HR; and central corneal thickness (CCT) were measured with Pentacam® HR and with ultrasound.
In 45 eyes of 45 patients (age 62.73±15.31), the AL was 23.35±1.49 mm. The CCT was 541.7±39.9 µm with Visante OCT, 549.7±39.2 µm with Pentacam® HR, and 534.3±41.3 µm with ultrasonic device. The ACD was 3.0±0.42 mm with IOLMaster, 3.26±0.95 mm with Visante OCT, and 3.06±0.41 mm with Pentacam® HR. In case of CCT measurements, data obtained with Pentacam HR correlated with the results of ultrasonic measurements (r=0.89; p<0.001) and Visante OCT measurements (r=0.88; p<0.001). Regarding ACD results, a significant correlation was observed between Pentacam HR and IOLMaster (r=0.95; p<0.0001) but they did not significantly correlate to Visante OCT data (r=0.23; p=0.12). Correlation was significant between AL and ACD measured with IOLMaster (r=0.67; p<0.001).
The CCT and ACD data show strong correlation between different devices.
眼科参数可通过不同技术和设备进行测量。我们的目的是使用两种光学设备测量眼前节参数，并将数据与超声技术进行比较。
使用IOLMaster测量眼轴长度（AL）；使用IOLMaster、Visante®光学相干断层扫描（OCT）和Pentacam® HR测定前房深度（ACD）；使用Pentacam® HR和超声测量中央角膜厚度（CCT）。
在45例患者（年龄62.73±15.31岁）的45只眼中，AL为23.35±1.49 mm。使用Visante OCT测量的CCT为541.7±39.9 µm，使用Pentacam® HR测量的为549.7±39.2 µm，使用超声设备测量的为534.3±41.3 µm。使用IOLMaster测量的ACD为3.0±0.42 mm，使用Visante OCT测量的为3.26±0.95 mm，使用Pentacam® HR测量的为3.06±0.41 mm。在CCT测量中，Pentacam HR获得的数据与超声测量结果（r=0.89；p<0.001）和Visante OCT测量结果（r=0.88；p<0.001）相关。关于ACD结果，Pentacam HR与IOLMaster之间观察到显著相关性（r=0.95；p<0.0001），但它们与Visante OCT数据无显著相关性（r=0.23；p=0.12）。IOLMaster测量的AL与ACD之间相关性显著（r=0.67；p<0.001）。
CCT和ACD数据显示不同设备之间有很强的相关性。
