对９０例３～１０岁低体重儿和７５例同龄足月正常体重儿进行立体视锐度检查。按年龄分组比较两组立体视异常率，≤６岁的两组间立体视异常率无显著差异（Ｐ＞０．０５）；＞６岁的两组间差异有显著性（Ｐ＜０．０５），低体重儿组的立体视异常率较高。在低体重儿组中，按胎龄分成早产儿及足月小样儿两组比较立体视异常率，两组间差异有显著性（Ｐ＜０．０５），早产儿组较高。提示出生体重及胎龄对立体视的发育有一定的影响，所以应重视对低体重儿、特别是早产低体重儿的眼科随访。
90 cases of 3 to 10-year-old children with low birth weight and 75 cases of full-term normal weight children with stereopsis examination. There was no significant difference in stereological abnormalities between the two groups (P> 0.05). There was a significant difference between two groups> 6 years old (P <0.05 ), Low-weight group of children with higher abnormal stereopsis. In low birth weight infants, gestational age was divided into preterm infants and full-term infants, compared with the two stereotactic anomalous rate, the difference between the two groups was significant (P <0.05), premature infants were higher. Tip birth weight and gestational age stereoscopic stereoscopic development have a certain impact, it should pay attention to low birth weight children, especially those with low birth weight preterm birth eye follow-up.
