原发性开角型青光眼不同发展阶段盘沿缺失的形态特征及其临床意义

Morphological characteristics of neuroretinal rim loss in the course of primary open angle glaucoma and its clinical significance

目的:探讨青光眼病情发展阶段盘沿缺失的形态特征。方法:对青光眼92眼和正常人124眼进行立体彩色视盘照像,侧重分析盘沿的形态。结果:与视力正常眼比较,青光眼不同病情阶段盘沿缺失有其好发区域。早期青光眼盘沿缺失在视盘颞下极明显,中期青光眼盘沿缺失在颞上极较为明显,极晚期青光眼盘沿仅保留视盘鼻侧区域,并且鼻上区大于鼻下区。结论:青光眼盘沿缺失的形态特征与青光眼性视野缺损的发展及筛板的形态密切相关。

AIM, To study the morphological characteristics of neuroretinal rim loss in the course of glaucoma. METHODS. The morphological characteristics of neuroretinal rim was studied, including the stereo color optic disc photographs of 92 glaucomatous eyes and 124 visually normal eyes. RESULTS, Compared with the visually normal eyes, glaucomatous neuroretinal rim loss occurred with preferable region depeneing on the stage of the disease, in the eye with modest glaucomatous damage, rim loss was most obvious in the inferotemporal disc region, in the eye with moderately progressed glaucomatous changes, rim was decreased much markedly in the superotemporal sector, in very advanced glaucoma, rim remnants usually were present only in the nasal disc region, at that stage, they were significantly larger in the superior nasal region than in the nasal inferior area. CONCLUSION： Patterns of glaucomatous neuroretinal rim loss were correlated with the progression of visual field defects and the morphology of the lamina cribrosa.
