High-pass resolution perimetry (HRP) enables one to estimate the number of functioning retinal ganglion-cells. We investigated the correlation between HRP and Humphrey Field Analyzer 630 in 35 eyes of 23 primary open-angle glaucoma and 75 eyes of 46 normal-tension glaucoma patients. In a total of 110 eyes, both functional channels and global deviation of HRP were significantly correlated with MD (r = 0.74, p < 0.01: r = -0.71, p < 0.01, respectively). Local deviation of HRP was also significantly correlated with corrected pattern standard deviation (r = 0.77, p < 0.01). These correlations tended to be higher in eyes with more advanced field changes than in those with fewer changes. These results indicate that HRP may be useful for evaluation of glaucomatous visual field abnormalities. The observed discrepancies between the two different methods in early stage glaucoma may be attributable to differences in physiological factors tested in these methods.
高通分辨率视野计（HRP）能够使人估计视网膜神经节细胞的功能数量。我们在23例原发性开角型青光眼患者的35只眼中以及46例正常眼压性青光眼患者的75只眼中研究了HRP与Humphrey视野分析仪630之间的相关性。在总共110只眼中，HRP的功能通道和整体偏差均与平均偏差显著相关（r分别为0.74，p < 0.01；r为 -0.71，p < 0.01）。HRP的局部偏差也与校正模式标准差显著相关（r = 0.77，p < 0.01）。与视野改变较少的眼睛相比，在视野改变较严重的眼睛中这些相关性往往更高。这些结果表明，HRP可能有助于评估青光眼性视野异常。在早期青光眼阶段观察到的两种不同方法之间的差异可能归因于这些方法所检测的生理因素的差异。
