PURPOSE
To identify differences in corneal hysteresis (CH) between primary open-angle glaucoma (POAG), pseudoexfoliative glaucoma patients (PXSG) and a healthy control group.
METHODS
In this retrospective study, CH was measured with the Ocular Response Analyzer. 90 subjects were evaluated, 30 subjects in each group. One eye per subject was analyzed.
RESULTS
In normal eyes, POAG and PXSG, CH was 9.8±1.6, 9.0±1.9 and 8.0±1.5 mm Hg, respectively. CH was significantly lower in PXSG patients than in POAG (p=0.042) and normal patients (p=0.0001), but no significance was found between the POAG and the normal group (p=0.23).
CONCLUSION
CH differs in the different groups and might be considered in glaucoma evaluation. Further studies with larger sample sizes are needed.
目的
确定原发性开角型青光眼（POAG）、剥脱性青光眼患者（PXSG）与健康对照组之间角膜滞后（CH）的差异。
方法
在这项回顾性研究中，使用眼反应分析仪测量CH。评估了90名受试者，每组30名。分析了每位受试者的一只眼睛。
结果
正常眼、POAG和PXSG的CH分别为9.8±1.6、9.0±1.9和8.0±1.5 mmHg。PXSG患者的CH显著低于POAG患者（p = 0.042）和正常患者（p = 0.0001），但POAG组与正常组之间无显著差异（p = 0.23）。
结论
不同组之间CH存在差异，在青光眼评估中可能需要考虑这一点。需要进行更大样本量的进一步研究。
