7小结
ORA与传统的非接触式眼压计(NCT)测量方法非常相似，但其测量的精确度却显著提高，且不受CCT的影响，并能测量CH，CRF等角膜生物力学特性因子，了解角膜的粘弹性和粘滞性等特点。它们可能提供了比单独CCT更多、更完整的在眼压测量中角膜的信息。其次，ORA对LASIK术后和圆锥角膜等角膜特别薄弱的患者能很好地测量眼压且能了解角膜生物力学特性的改变。此外,ORA也广泛适用于角膜厚度偏离平均值、GAT无法准确测量眼压的病例,ORA的测量原理决定了它能够准确测量（含义是测量的系统误差<0.5mmHg）。总之，ORA允许我们去测量那些以前被大多临床医师忽略的角膜特性，那些寻求角膜参数在眼压测量中影响的新技术最终可能导致青光眼治疗的改变。同时这些新技术使测量的眼压更加接近于真实的眼内压。但目前尚需进一步研究明确的是ORA测量眼压及角膜参数对青光眼治疗的指导作用。此外，ORA在青光眼患者和已经使用药物降低眼压的患者中的应用尚需进一步研究。
