The optic disc topography of 11 eyes of 11 glaucoma-like discs without increased intraocular pressure or visual field loss was compared with that of 11 eyes of 11 relative early stage normal-tension glaucomas. There were no statistically significant differences between the two groups in terms of optic disc parameters measured with a Rodenstock Optic Nerve Head Analyzer Plus, except that the inferior quadrant of the neuroretinal rim area of the normal-tension glaucoma discs was significantly smaller than that of the glaucoma-like discs. Also, in the Humphrey automated visual field, only the superior part of the Total Deviation score of normal-tension glaucoma eyes corresponding to the inferior disc changes was significantly lower than that of glaucoma-like discs. When the data of the two groups were pooled, the inferior quadrant of the neuroretinal rim area significantly correlated with the visual field loss in the group of eyes with a rim area smaller than 0.198 mm2. These results seem to suggest that some of the glaucoma-like discs might be early normal-tension glaucoma.
将11例眼压未升高且无视野缺损的青光眼样视盘的11只眼的视盘地形图，与11例相对早期正常眼压性青光眼的11只眼进行比较。在用Rodenstock视神经乳头分析仪Plus测量的视盘参数方面，两组之间无统计学显著差异，只是正常眼压性青光眼视盘神经视网膜边缘区域的下象限明显小于青光眼样视盘。此外，在Humphrey自动视野检查中，仅正常眼压性青光眼眼与视盘下方改变相对应的总偏差得分的上半部分明显低于青光眼样视盘。当将两组数据合并时，在边缘区域小于0.198平方毫米的眼组中，神经视网膜边缘区域的下象限与视野缺损显著相关。这些结果似乎表明，一些青光眼样视盘可能是早期正常眼压性青光眼。
