Abstract

Background: Vitreous chamber volume (VCV) in humans can be accurately measured using magnetic resonance imaging (MRI) combined with ITK-SNAP analysis software. This study explores the relationship between VCV and axial length (AL).

Methods: This study included 46 healthy individuals, encompassing a total of 92 eyes. Individuals with a history of eye conditions were excluded from the study. AL measurements were obtained using the Lenstar 900 (Haag-Streit, Switzerland). VCV was assessed through MRI using the Ingenia 3.0T system (Philips Medical Systems, Netherlands), with VCV analysis performed using ITK-SNAP analysis software version 3.8.0. The correlation between AL and VCV was evaluated using Pearson linear correlation coefficient, and a logistic regression model was employed to predict VCV.

Results: The sample consisted of 92 eyes from 46 individuals, including 28 women and 18 men. The average VCV was 6193±1135.9 mm 3 for women and 6324.3±886.7 mm 3 for men. The mean AL for women was 24.70±2.78 mm, while for men it was 24.66±1.70 mm. A significant correlation between AL and VCV was observed ( P <0.001).

Conclusions: VCV can be accurately estimated through AL measurements, offering a clinically relevant method for assessing VCV.

用轴向长度测量玻璃腔体积的估计。

背景：磁共振成像（MRI）结合ITK-SNAP分析软件可以精确测量人体玻璃体腔体积（VCV）。本研究探讨了VCV与轴向长度（AL）的关系。方法：本研究纳入46名健康个体，共92只眼。有眼部病史的个体被排除在研究之外。AL测量使用Lenstar 900 （Haag-Streit, Switzerland）获得。使用Ingenia 3.0T系统（Philips Medical Systems，荷兰）通过MRI评估VCV，使用ITK-SNAP分析软件3.8.0进行VCV分析。采用Pearson线性相关系数评价AL与VCV的相关性，并采用logistic回归模型预测VCV。结果：样本包括来自46个人的92只眼睛，其中包括28名女性和18名男性。女性平均VCV为6193±1135.9 mm3，男性为6324.3±886.7 mm3。女性平均AL为24.70±2.78 mm，男性为24.66±1.70 mm。AL与VCV之间存在显著相关性(p)。结论：通过AL测量可以准确估计VCV，为临床评估VCV提供了一种相关的方法。

期刊介绍： The Journal of Craniofacial Surgery serves as a forum of communication for all those involved in craniofacial surgery, maxillofacial surgery and pediatric plastic surgery. Coverage ranges from practical aspects of craniofacial surgery to the basic science that underlies surgical practice. The journal publishes original articles, scientific reviews, editorials and invited commentary, abstracts and selected articles from international journals, and occasional international bibliographies in craniofacial surgery.
