The disappearance of the anterior vascular capsule of the lens (tunica vasculosa lentis) in the preterm infant has been established to be useful in accurately estimating gestational age between the twenty-seventh and thirty-fourth weeks in infants appropriate or small for gestational age. Six infants have been studied with abnormalities of the anterior vascular capsule of the lens in which congenital TORCH infection has been documented (1 toxoplasmosis, 2 rubella, 2 cytomegalovirus, and 1 herpes simplex virus). Since the anterior vascular capsule generally atrophies symmetrically and completely after the thirty-fourth week of gestation, the findings of marked asymmetry and/or persistence and hypertrophy of the anterior vascular capsule of the lens warrants initiation of TORCH studies in the newborn infant.
早产儿晶状体前血管膜（晶状体血管膜）的消失已被证实有助于准确估计孕27至34周适于胎龄或小于胎龄婴儿的胎龄。对6例晶状体前血管膜异常的婴儿进行了研究，这些婴儿均有先天性TORCH感染的记录（1例弓形虫病、2例风疹、2例巨细胞病毒感染和1例单纯疱疹病毒感染）。由于妊娠34周后晶状体前血管膜通常会对称且完全萎缩，因此晶状体前血管膜明显不对称和/或持续存在及肥大的表现提示应对新生儿进行TORCH检查。
