角膜光密度在临床中的应用

Application of corneal densitometry in clinical practices

角膜光密度是角膜组织的一种生物学性质,与角膜的透明性有关,可以用来描述角膜的透明程度。目前角膜光密度已经应用于角膜疾病的辅助诊断与严重程度评估,还用于角膜手术疗效的评估和术后病情的随访,同时也可用于全身系统性疾病的角膜状态评估。Pentacam角膜光密度测定是一种客观、无创、可重复评估角膜透明性的方法,对角膜以及全身健康程度的监测都有重要的参考价值。本文就角膜光密度在临床中的应用进行综述。

Corneal densitometry is a biological property of corneal tissue,which is related to the transparency of cornea,and can be used to describe the degree of corneal transparency.At present,corneal densitometry has been used in the auxiliary diagnosis and severity evaluation of corneal diseases,as well as in the evaluation of the surgical outcome and the postoperative follow-up,even some systemic diseases affecting the cornea.The measurement of corneal densitometry is an objective,non-invasive and repeatable method to evaluate corneal transparency,which has important reference values for the monitoring of corneal and systemic health.In this article,the application of corneal densitometry in clinical practices was reviewed.
