Ocular and/or visual defects were diagnosed by age 2 years in 2.1% of infants born in 1984 in one health district. Infants of low birth weight or infants requiring special care in the neonatal period had a two and a half times greater risk of vision and ocular defects than the remainder of the population. In particular, the rate of squint and neurological disease affecting the visual system was significantly greater in this high risk group than in the low risk group. The degree of visual impairment in the high risk group tended to be more severe than in the low risk group. Overall, however, the majority of children with vision or ocular defects (85%) were in the low risk group.
在某一卫生区,1984年出生的婴儿中,2.1%在2岁时被诊断出有眼部和/或视觉缺陷。低体重婴儿或在新生儿期需要特殊护理的婴儿出现视力和眼部缺陷的风险是其他人群的2.5倍。特别是,这一高风险组中斜视和影响视觉系统的神经疾病发生率明显高于低风险组。高风险组的视力损害程度往往比低风险组更严重。然而,总体而言,大多数有视力或眼部缺陷的儿童(85%)属于低风险组。
