In the period 1980-1987 ocular examinations were performed on 185 infants with a very low birthweight (less than 1500 g) at the age of nine months corrected for the duration of pregnancy. The mean gestational age of the infants was 30 weeks, while the mean birthweight was 1160 g. The mean spherical refraction was 0.9 D (S.D. 1.3 D), the mean astigmatism was C-0.6 D (S.D. 1.0 D), while convergent strabismus was found in 10% of the patients. The purpose of the investigation was to see if there was a relation between spherical equivalent of refraction, astigmatism and strabismus on the one hand and 11 perinatal parameters and cerebral palsy diagnosed at the age of nine months on the other hand. Statistical analysis was performed with the Student t-test. No significant correlation between the findings of ocular examination and the perinatal parameters could be detected.
在1980年至1987年期间，对185名极低出生体重（低于1500克）的婴儿进行了眼部检查，检查时间为矫正胎龄9个月时。婴儿的平均胎龄为30周，平均出生体重为1160克。平均球镜屈光度为0.9 D（标准差1.3 D），平均散光为C-0.6 D（标准差1.0 D），10%的患者存在内斜视。该研究的目的是观察一方面屈光等效球镜、散光和斜视与另一方面11个围产期参数及9个月时诊断的脑瘫之间是否存在关联。采用学生t检验进行统计分析。未检测到眼部检查结果与围产期参数之间存在显著相关性。
