The aim of the study was to compare different methods for pupillometry, namely the Goldmann perimeter (gp), the Colvard pupillometer (cp) and the Procyon Video pupillometer (pvp). For the pvp three different illuminations were available: mesopic high, mesopic low, and scotopic.
The size of the pupil was measured in 100 eyes (50 healthy subjects) with the three different methods. We examined 29 females (58 %) and 21 males (42 %) with an average age of 25.16 years, ranging from 18 to 30 years.
For the Goldmann perimeter, a mean pupil diameter of 4.39 mm +/- 0.62 mm was found under mesopic conditions (1.40 lux). For the Colvard pupillometer for scotopic conditions (0 lux), a mean pupil diameter of 6.80 mm +/- 0.81 mm was found. For pvp the pupil diameter ranged from 7.06 mm +/- 0.71 mm for scotopic (0.04 lux), over 6.24 mm +/- 0.80 mm for mesopic low (0.40 lux) to 4.65 mm +/- 0.73 mm for mesopic high conditions (4.00 lux).
The comparison of the results showed a high correlation between the Goldmann perimeter and the Procyon Video Pupillometer for mesopic high with a minimum difference of 0.25 +/- 0.69 mm. By addition of 2.67 mm to the mesopic measurement of the Goldmann perimeter, the results for the Procyon Video pupillometer at the scotopic level, by addition of 2.4 mm the scotopic measurement of the Colvard pupillometer could be achieved.
本研究的目的是比较不同的瞳孔测量方法，即戈德曼视野计（gp）、科尔瓦德瞳孔计（cp）和普罗西昂视频瞳孔计（pvp）。对于pvp，有三种不同的照明条件：中亮、中暗和暗视。
使用三种不同方法对100只眼睛（50名健康受试者）的瞳孔大小进行了测量。我们检查了29名女性（58%）和21名男性（42%），平均年龄为25.16岁，年龄范围在18至30岁之间。
在中亮条件下（1.40勒克斯），使用戈德曼视野计测得平均瞳孔直径为4.39毫米±0.62毫米。在暗视条件下（0勒克斯），使用科尔瓦德瞳孔计测得平均瞳孔直径为6.80毫米±0.81毫米。对于pvp，暗视（0.04勒克斯）时瞳孔直径为7.06毫米±0.71毫米，中暗（0.40勒克斯）时为6.24毫米±0.80毫米，中亮条件（4.00勒克斯）时为4.65毫米±0.73毫米。
结果比较显示戈德曼视野计与中亮条件下的普罗西昂视频瞳孔计之间具有高度相关性，最小差异为0.25±0.69毫米。将戈德曼视野计中亮测量值加上2.67毫米，可得到普罗西昂视频瞳孔计在暗视水平的测量结果；将科尔瓦德瞳孔计暗视测量值加上2.4毫米，也可得到相应结果。
