Abstract
Measurements of peripheral visual acuity allow quantitative estimations of retino-cortical neural channels. Analysis of results from high-pass resolution perimetry revealed that about 2/3 of all channels are contained within 30 degrees of visual field eccentricity and that loss of 1/3 raises the average threshold level about 1 decibel. The analytical procedure can be applied to any type of visual field defect.
摘要
周边视敏度的测量可对视网膜 - 皮质神经通道进行定量评估。高通分辨率视野检查结果分析显示，所有通道中约三分之二包含在视野偏心度30度范围内，且三分之一通道的丧失会使平均阈值水平提高约1分贝。该分析程序可应用于任何类型的视野缺损。
