The aim of this study was to assess the influence of common perinatal risk factors on the disappearance of the anterior vascular capsule of the lens (AVCL). Direct ophthalmologic examinations were performed on 75 neonates (27 to 35 weeks gestational age) in the first 24 hours after birth, using the degree of involution of the AVCL to estimate gestational age in high risk pregnancy. Our results show that the gradual disappearance of the AVCL is not influenced by perinatal risk factors, such as maternal preeclampsia, prenatal administration of steroids, neonatal infection and low birth weight, confirming the clinical value of this test in the assessment of gestational age in high risk babies.
本研究的目的是评估常见围产期危险因素对晶状体前血管膜（AVCL）消失的影响。对75例出生后24小时内的新生儿（胎龄27至35周）进行直接眼科检查，利用AVCL的退化程度来估计高危妊娠中的胎龄。我们的结果表明，AVCL的逐渐消失不受围产期危险因素的影响，如母亲先兆子痫、产前使用类固醇、新生儿感染和低出生体重，这证实了该检查在评估高危婴儿胎龄方面的临床价值。
