我们研究了40对正常眼压性青光眼和高眼压性青光眼患者的眼部特征，这些患者的视野损害程度、瞳孔大小和视力都非常接近。为了确定正常眼压性青光眼和高眼压性青光眼患者的视野损害是否存在差异，我们研究了患者未受干扰的视野区域的特征。我们计算了正常位置的数目、聚集的正常位置的数目以及正常位置的最大聚类的大小。结果表明，在相同的损伤程度下，正常张力组的个体具有更大的正常敏感区域，因此更多的局部性损伤。患者数据和对照数据的比较表明，当一对中正常张力的成员在任何参数中有更大的值时，配对的差异更大。结果支持眼压低的青光眼患者有更多的局限性损害，而高眼压的青光眼患者有更多的弥漫性损害的假说。
We studied the ocular characteristics of 40 pairs of normal-tension and high-tension glaucoma patients who matched closely for the extent of field damage, pupil size, and visual acuity. To determine if there were differences in visual field damage between patients with normal-tension and high-tension glaucoma, we studied characteristics of the areas of the patients'' visual fields that were undisturbed. We computed the number of normal locations, the number of clustered normal locations and the size of the largest cluster of normal locations. The results showed that for an equivalent extent of damage, the individuals in the normal-tension group had greater areas with normal sensitivity, hence more localized damage. A comparison of the patient data to control data showed that paired differences were larger when the normal-tension member of a pair had a larger value in any of the parameters. The results support the hypothesis that glaucoma patients with lower intraocular pressures have more localized damage and those with higher intraocular pressures have more diffuse damage.
