目的：根据胎龄提供正常的晶状体和眼眶测量范围。方法：对335例妊娠15~40周的正常妊娠妇女进行评估。晶状体和眼眶测量被添加到正常胎儿的常规生物测量中。结果：胎龄与晶状体直径(R-2=0.89；P<；0.0001)、周长(R-2=0.89；P<；0.0001)、表面积(R-2=0.9；P<；0.0001)呈显著的线性相关。GA与眼眶直径(R-2=0.92P<；0.0001)、周长(R-2=0.92P<；0.0001)和表面积(R-2=0.95P<；0.0001)也呈线性相关。双顶径与晶状体直径(R-2=0.9；P<；0.0001)和眼眶直径(R-2=0.94；P<；0.0001)呈线性增长关系。结论：晶状体和眼眶测量为胎儿生长发育提供了标准化数据。这些数据也可能有助于检测胎儿的眼部异常。(C)2002年国际妇产科联合会。爱思唯尔科学爱尔兰有限公司出版。版权所有。
Objectives: To present normal lens and orbital measurement ranges by gestational age. Methods: Three hundred and thirty-five women with uneventful pregnancies were evaluated from the 15th to the 40th week of gestation. Lens and orbital measurements were added to routine biometric measurements for normal fetuses. Results: A strong linear correlation was observed between gestational age (GA) and lens diameter (R-2 = 0.89; P < 0.0001), circumference (R-2 = 0.89; P < 0.0001), and surface (R-2 = 0.90; P < 0.0001). A linear correlation was also found between GA and orbital diameter (R-2 = 0.92; P < 0.0001), circumference (R-2 = 0.92; P < 0.0001) and surface (R-2 = 0.95; P < 0.0001). A linear growth function was observed between biparietal diameter and both lens diameter (R-2 = 0.90; P < 0.0001) and orbital diameter (R-2 = 0.94; P < 0.0001). Conclusions: Lens and orbital measurements provide normative data for fetal growth and development. These data may be also helpful in detecting fetal ocular anomalies.
