高眼压、视野缺损和视乳头凹陷及萎缩构成了青光眼的三联征,特别是在单纯型青光眼中。但是在此三联征中,病理性视乳头凹陷和萎缩的形态学改变,多少年来一直被认为,只有当病程进展到中、后期时,才能显现出来。因而青光眼的早期病理性改变,只有依靠细微的视野检查才能发现。近些年来,相继有不少眼科学者对早期青光眼的视乳头凹陷进行了研究,从Armaly(1967)研究杯盘比开始,到Tomlinson(研究杯盘面积比)、Holm等
High intraocular pressure, visual field defects and optic disc depression and atrophy constitute the triad of glaucoma, especially in simple glaucoma. However, in this triad, pathological optic disc depression and atrophy of the morphological changes, for many years has been considered, only when the course of disease to the middle and late to be revealed. Therefore, the early pathological changes of glaucoma, only rely on subtle visual field examination can be found. In recent years, many ophthalmologists have studied the papillae of early glaucoma. From Armaly’s (1967) study on cup-to-plate ratio to Tomlinson’s study on cup-to-cup area ratio, Holm et al.
