目的：定量观察人类晶状眼和假性晶状眼睫状肌直径的体内调节变化。单位：皮斯卡塔韦市umdnj -罗伯特·伍德·约翰逊医学院外科/生物工程系，美国新泽西州纽瓦克市umdnj -新泽西医学院眼科和视觉科学研究所。方法：采集年龄22 ~ 91岁的40例48眼、32例有晶状体的1眼和8例单眼人工晶状体植入术患者的双眼图像（美国爱尔康实验室）。在生理调节和休息调节时获取图像，并测量睫状肌环的直径。结果：结果显示睫状肌在一生中保持活跃。其直径的调节变化（平均0.64 mm） (P
PURPOSE: To quantify in vivo accommodative changes in the aging human ciliary muscle diameter in phakic and pseudophakic eyes.SETTING: Department of Surgery/Bioengineering, UMDNJ-Robert Wood Johnson Medical School, Piscataway, and the Institute of Ophthalmology and Visual Science UMDNJ-New Jersey Medical School, Newark, New Jersey, USA.METHODS: Images were acquired from 48 eyes of 40 people between the ages of 22 and 91 years, I eye of 32 phakic volunteers and both eyes of 8 patients who had monocular implantation of a single-piece AcrySof intraocular lens (IOL) (Alcon Laboratories). Images were acquired during physiological accommodation and with accommodation at rest, and the diameter of the ciliary muscle ring was measured.RESULTS: Results show the ciliary muscle remains active throughout life. The accommodative change in its diameter (mean 0.64 mm) (P
