Background. To evaluate differences between Goldmann Applanation Tonometry (GAT) and Dynamic Controur Tonometry (DCT) following trabeculectomy. Methods. Thirty eight glaucomatous eyes with a history of trabeculectomy (Trabeculectomy group, TG), 20 eyes without a history of trabeculectomy but with a history of latanoprost use (Latanoprost group, LG), and 19 nonglaucomatous eyes (Control group, CG) were included. GAT-IOP, DCT-IOP, the difference between them (dIOP), the central corneal thickness (CCT), the axial length (AL), and the depth of the anterior chamber (ACD) were measured. Results. dIOP was significantly higher in TG (5.19 mmHg) than in LG (4.01 mmHg) and CG (1.98 mmHg). Correlations between AL and dIOP were statistically significant in both TG and LG but not in CG whereas correlations between dIOP and other clinical parameters examined were statistically not significant in all groups. Conclusions. The significantly higher dIOP in TG implies that the bio-mechanical properties of the ocular walls are altered following trabeculectomy.
背景。评估小梁切除术后Goldmann压平眼压计（GAT）和动态轮廓眼压计（DCT）之间的差异。方法。纳入38只曾行小梁切除术的青光眼患眼（小梁切除术组，TG）、20只无小梁切除术史但有使用拉坦前列素史的患眼（拉坦前列素组，LG）和19只非青光眼患眼（对照组，CG）。测量GAT眼压、DCT眼压、两者之间的差值（dIOP）、中央角膜厚度（CCT）、眼轴长度（AL）和前房深度（ACD）。结果。TG组的dIOP（5.19 mmHg）显著高于LG组（4.01 mmHg）和CG组（1.98 mmHg）。AL与dIOP之间的相关性在TG组和LG组中具有统计学意义，但在CG组中无统计学意义；而dIOP与其他所检查临床参数之间的相关性在所有组中均无统计学意义。结论。TG组中显著更高的dIOP提示小梁切除术后眼壁的生物力学特性发生了改变。
