The accuracy of contact tonometry may be compromised in cases with disorders affecting central corneal bio-mechanical properties. This study examined the reliability of rebound tonometry (RT) on the area of corneo-scleral limbus, instead of the conventional central corneal area, and the correlation of findings with ocular biometric parameters.
This is a prospective cross-sectional study performed at the Department of Ophthalmology of the University Hospital of Heraklion, in Crete, Greece. Consecutive cataract surgery candidates without concomitant ocular pathology, apart from cataract, were included. RT was performed on the central cornea (central RT, CRT) as well as on the limbus and scleral spur area (limbal RT, LRT). Findings were correlated with Goldmann applanation tonometry (GAT) as well as axial length (AL), central corneal thickness (CCT), and corneal curvature (CC) measurements.
LRT readings were significantly correlated with central CRT as well as with GAT readings, whereas respective correlations with other parameters examined were not statistically significant.
LRT may be used as an alternative tool in clinical practice to determine intraocular pressure when conventional devices and techniques might be inadequate or unreliable.
在影响中央角膜生物力学特性的疾病病例中，接触式眼压测量法的准确性可能会受到影响。本研究考察了回弹眼压测量法（RT）在角膜缘区域而非传统中央角膜区域的可靠性，以及测量结果与眼部生物测量参数的相关性。
这是一项在希腊克里特岛伊拉克利翁大学医院眼科进行的前瞻性横断面研究。纳入了除白内障外无其他眼部病变的连续白内障手术候选者。在中央角膜（中央RT，CRT）以及角膜缘和巩膜突区域（角膜缘RT，LRT）进行RT测量。测量结果与Goldmann压平眼压测量法（GAT）以及眼轴长度（AL）、中央角膜厚度（CCT）和角膜曲率（CC）测量值进行相关性分析。
LRT测量值与中央CRT以及GAT测量值显著相关，而与所检查的其他参数的相应相关性无统计学意义。
当传统设备和技术可能不足或不可靠时，LRT可作为临床实践中测定眼压的替代工具。
