Based on a precise definition of boundaries of the ciliary sulcus, a new anatomical method was used to measure the diameter of the ciliary sulcus in postmortem eyes. In each of 41 globes, 24 different ciliary sulcus diameters were measured and were compared with the axial length, measured by ultrasonography. The mean ciliary sulcus diameter was 11.25 mm (SD = 0.38 mm). By linear regression, the axial length values were significantly correlated with ciliary sulcus diameters. In addition, our data suggest that existence of two groups of eyes differentiated exclusively by the diameter of the ciliary sulcus, independent of the axial length. We propose that the displacement of the pars plicata corporis ciliaris from the peripheral iris to the iris root during the embryonic period may be incomplete in eyes of shorter axial length. The findings of the present study may play a role in cataract surgery in which an intraocular lens is inserted into the ciliary sulcus.
基于对睫状沟边界的精确界定，采用一种新的解剖学方法测量了尸检眼的睫状沟直径。在41只眼球中，每只均测量了24个不同的睫状沟直径，并与通过超声检查测量的眼轴长度进行比较。睫状沟平均直径为11.25毫米（标准差=0.38毫米）。通过线性回归分析，眼轴长度值与睫状沟直径显著相关。此外，我们的数据表明，存在两组仅由睫状沟直径区分的眼睛，与眼轴长度无关。我们提出，在胚胎期，睫状突从周边虹膜向虹膜根部的移位在眼轴较短的眼睛中可能不完全。本研究结果可能在将人工晶状体植入睫状沟的白内障手术中发挥作用。
