The authors developed an automated method of pupil perimetry by linking an infrared video pupillometer to a Humphrey Field Analyzer. Software was developed to automatically analyze the pupil responses to focal light stimuli and display the results graphically. All 76 locations of Humphrey program 30-2 could be tested twice within 5.5 minutes and the relative sensitivity of the field was determined by comparing the amplitude of pupil constriction or latency time at each stimulus location. The mean pupil responses within annular areas at 3 degrees, 9 degrees, 15 degrees, 21 degrees, and 27 degrees were shown to be linearly related to log stimulus intensity over a 15 dB range under low level mesopic conditions (3.15 asb bowl background). In normal subjects, the superior temporal quadrant usually had the greatest mean pupillomotor response and the inferior nasal quadrant had the least. Pupil responses in the temporal field were larger than corresponding locations in the nasal field. Patients with visual field defects who underwent testing by pupil perimetry showed pupillary deficits in the same location within the field, providing evidence that pupil perimetry may be a useful, objective means of assessing visual field function.
作者通过将红外视频瞳孔计与汉弗莱视野分析仪相连，开发出一种自动瞳孔视野计方法。开发了软件以自动分析瞳孔对焦点光刺激的反应，并以图形方式显示结果。汉弗莱程序30 - 2的所有76个位置可在5.5分钟内测试两次，通过比较每个刺激位置的瞳孔收缩幅度或潜伏期来确定视野的相对敏感度。在低水平中间视觉条件下（3.15 asb碗状背景），3度、9度、15度、21度和27度环形区域内的平均瞳孔反应在15分贝范围内与对数刺激强度呈线性相关。在正常受试者中，颞上象限通常平均瞳孔运动反应最大，鼻下象限最小。颞侧视野的瞳孔反应大于鼻侧视野的相应位置。接受瞳孔视野计测试的视野缺损患者在视野内相同位置出现瞳孔缺陷，这证明瞳孔视野计可能是评估视野功能的一种有用的客观方法。
