Abstract

Purpos: To investigate the spatial placements of the horizontal and vertical ciliary sulcus through ultrasound biomicroscopy (UBM) analysis.

Setting: EYE & ENT Hospital of Fudan University, Shanghai, China.

Design: Prospective observational clinical study.

Methods: This study comprised 82 eyes of preoperative ICL candidates with myopic implantable collamer lens (ICL). UBM was used to measure the ciliary sulcus to sulcus (STS), central distance from endothelium to STS (ASL) crystalline lens to STS (STSL), the angle to angle distance (ATA) and ACD to crystalline lens (ACD-L) in both the horizontal and vertical orientations. Mean keratometry (Km), axial lengths (AL), and horizontal white-to-white distance (WTW) were also recorded.

Results: The mean ASL was 3.574 ± 0.183 and 3.725 ± 0.198 mm, while the mean STSL was 0.488 ± 0.175 and 0.629 ± 0.161 mm in the horizontal and vertical orientations, respectively (P < .001). The vertical STSL (vSTSL) exceeded the horizontal STSL (hSTSL) by a mean difference of 0.141±0.128 mm, and similarly, the vASL exceeded the hASL by a mean difference of 0.151±0.137 mm. Both the hSTSL and vSTSL showed a negative correlation with ACD (P < .001). The difference in STSL (vSTSL-hSTSL) was positively correlated with vSTSL, vASL, and the difference in STS (all P < .05) and negatively correlated with hSTSL and hASL (both P < .05).

Conclusions: The ciliary sulcus is typically located more posteriorly in the vertical orientation than in the horizontal orientation.

超声生物显微镜直接测量近视眼睫状沟水平和垂直位置。

目的：通过超声生物显微镜（UBM）分析水平和垂直睫状沟的空间位置。单位：上海复旦大学附属眼科医院。设计：前瞻性观察性临床研究。方法：本研究纳入82眼近视人工晶状体植入术患者。用UBM测量睫状体睫状体沟到睫状体沟（STS）、内皮细胞到睫状体沟（ASL）的中心距离、晶状体到睫状体沟（STSL）的角度距离（ATA）和睫状体到晶状体的角度距离（ACD- l）。平均角膜度数（Km）、轴向长度（AL）和水平白到白距离（WTW）也被记录下来。结果：水平、垂直方向平均ASL分别为3.574±0.183、3.725±0.198 mm， STSL分别为0.488±0.175、0.629±0.161 mm （P < 0.001）。垂直STSL （vSTSL）与水平STSL （hSTSL）的平均差值为0.141±0.128 mm， vASL与hASL的平均差值为0.151±0.137 mm。hSTSL、vSTSL与ACD呈负相关（P < 0.001）。STSL差异（vSTSL-hSTSL）与vSTSL、vASL、STS差异呈正相关（均P < 0.05），与hSTSL、hASL呈负相关（均P < 0.05）。结论：睫状沟在垂直方向上的位置比在水平方向上的位置更后。
