目得：观察日本不同年龄组在不同照明条件下的近视力和远视力下的瞳孔大小。单位：日本东京牙科大学水道桥医院眼科。使用开放式红外视频瞳孔计，在明视条件下，前瞻性测量受试者注视30 cm或3 m目标时的水平和垂直瞳孔大小（照明500勒克斯）和中间视觉（照明5勒克斯）条件。按年龄对结果进行分析，并对各种多焦点IOL的益处进行了评估。结果：该研究包括140只眼（70例受试者; 14至94岁）。当注视远/近时，明视垂直瞳孔大小的平均+/-标准差从3.77 +/- 0.23/3.50 +/- 0.33 mm（< 20岁）降至2.20 +/- 0.30/1.95 +/- 0.20 mm（80岁以上），60岁后瞳孔大小稳定。视远/视近时的中间视垂直瞳孔大小从6.35 +/- 0.11/6.27 +/- 0.14 mm（< 20岁）降至3.42 +/- 0.30/3.21 +/- 0.28 mm（80岁以上）。瞳孔大小随年龄增长而减小，60岁以后趋于稳定（单因素方差分析，P
PURPOSE: To observe pupil sizes with near and distance vision under different lighting conditions in different Japanese age groups.SETTING: Department of Ophthalmology, Tokyo Dental College Suidobashi Hospital, Tokyo, Japan.METHODS: Using an open view-type infrared video pupillometer, the horizontal and vertical pupil sizes were measured prospectively with subjects gazing at 30 cm or 3 m targets under photopic (illumination 500 lux) and mesopic (illumination 5 lux) conditions. The results were analyzed by age, and the benefits with various multifocal IOLs were evaluated.RESULTS: The study comprised 140 eyes (70 subjects; 14 to 94 years). The mean +/- standard deviations of photopic vertical pupil sizes when gazing far/near decreased from 3.77 +/- 0.23/3.50 +/- 0.33 mm (< 20 years) to 2.20 +/- 0.30/1.95 +/- 0.20 mm (over 80 years), with pupil sizes stabilizing after 60 years. The mesopic vertical pupil sizes when gazing far/near decreased from 6.35 +/- 0.11/6.27 +/- 0.14 mrn (< 20 years) to 3.42 +/- 0.30/3.21 +/- 0.28 mm (over 80 years). The pupil sizes decreased with age until 60 years and stabilized (1-way analysis of variance, P
