    摘要:

    青光眼是一种以进行性视盘变化和视野损失为特征的眼压相关性疾病。杯盘比在过去40a来都是评价视盘青光眼性改变的标准方法。然而我们却发现是一些小视盘的患者有典型青光眼性视野损失,而一些大视盘的患者却没有视野损失。杯盘比的检查效力和可重复性都低于一些新的检查方法。视盘损伤可能度分级(DDLS)是一种衡量视盘盘沿面积、并且校正了视盘大小等影响因素的新型视盘评价方法。DDLS也许是评价青光眼视盘的更为优化的方法。

    Abstract:

    Glaucoma is a kind of progressive disease characterized by distinctive defects of optic disc cupping and visual field loss associated with or without intraocular pressure elevated.The cup/disc ratio is the standard way to describe the optic disc in the past 40 years.But the fact is that there were cases in which glaucomatous visual field loss was associated with a small cup,and cases in which visual field loss was not present even though the cup was large.The cup/disc ratio is less valid and reproducible than new methods.The Disc Damage Likelihood Scale(DDLS),which is based on the appearance of the neuroretinal rim of the optic disc,corrected for the disc diameter,may be a better system to evaluate the optic disc.
