To establish normative values for the anterior segment in premature infants in relation to postconceptional age and birth weight.
Anterior segments were measured in 39 premature infants, 25 to 39 weeks' gestational age by use of ultrasound biomicroscopy and a muscle hook with topical anaesthesia.
Anterior chamber depth, trabecular-iris angle, angle opening (trabecular-iris) distances at 250 and 500 microns from the scleral spur, and the thickness of the thickest part of the iris showed linear increases in relation to postconceptional age and birth weight.
Ultrasound biomicroscopy is a powerful tool for obtaining precise images and measurement of the anterior segment in preterm neonates. Normative values were established for anterior segment dimensions in relation to postconceptional age and birth weight.
建立与孕龄和出生体重相关的早产儿眼前节的正常参考值。
对39例孕龄为25至39周的早产儿,在局部麻醉下使用超声生物显微镜和肌肉钩测量眼前节。
前房深度、小梁-虹膜角、距巩膜突250和500微米处的角开放(小梁-虹膜)距离以及虹膜最厚部分的厚度与孕龄和出生体重呈线性增加关系。
超声生物显微镜是获取早产儿眼前节精确图像和测量的有力工具。建立了与孕龄和出生体重相关的眼前节尺寸的正常参考值。
