Grating acuity and visual fields were assessed in 66 children who had had perinatal asphyxia (ASPH). Also tested were 41 healthy preterm children (H-PT). Subjects were tested at birth to one month, and four, nine, 12, 17, 24, 30 and 36 months corrected age. The mean acuity scores of the ASPH group were lower than those of the H-PT group at most test ages, and significantly so at 30 and 36 months. The mean visual field size of the infants in the ASPH group was significantly smaller than that of the H-PT group at nine, 12, 30 and 36 months. No significant effects were found for preterm vs term birth, gestational age at birth, degree of asphyxia and presence of strabismus. However, central nervous system abnormalities (intraventricular haemorrhage and periventricular leukomalacia) were related to deficits in acuity and visual field size.
对66名有围产期窒息（ASPH）的儿童进行了光栅视力和视野评估。还测试了41名健康的早产儿童（H-PT）。在出生至1个月、矫正年龄4个月、9个月、12个月、17个月、24个月、30个月和36个月时对受试者进行测试。在大多数测试年龄，ASPH组的平均视力得分低于H-PT组，在30个月和36个月时差异显著。在9个月、12个月、30个月和36个月时，ASPH组婴儿的平均视野大小显著小于H-PT组。未发现早产与足月产、出生时的胎龄、窒息程度和斜视的存在有显著影响。然而，中枢神经系统异常（脑室内出血和脑室周围白质软化）与视力和视野大小的缺陷有关。
