早产儿长期暴露在环境中的托儿所光照水平，已被发现会对动物的视网膜造成损害。我们通过比较74名来自标准明亮托儿所环境的早产儿视网膜病变的发生率(中位数光照水平，60英尺蜡烛[FTC])和154名出生体重相近但光照水平降低的婴儿(中位数，25 FTC)，前瞻性地调查了两家重症监护托儿所暴露于光线的影响。早产儿视网膜病变的发生率在暴露于更明亮的托儿所灯光的婴儿组中更高，特别是在出生体重低于1000g的婴儿组(86%对54%，经卡方检验P<0.01)。我们的结论是，医院托儿所普遍存在的高水平环境照明可能是导致早产儿视网膜病变的一个因素，关于当前照明实践的安全标准应该重新评估。
The preterm infant is subjected to prolonged exposure to ambient nursery illumination at levels that have been found to produce retinal damage in animals. We prospectively investigated the effect of exposure to light in two intensive care nurseries by comparing the incidence of retinopathy of prematurity among 74 infants from the standard bright nursery environment (median light level, 60 foot-candles [ftc]) with the incidence among 154 infants of similar birth weight for whom the light levels were reduced (median, 25 ftc). There was a higher incidence of retinopathy of prematurity in the group of infants who had been exposed to the brighter nursery lights, particularly in those with birth weights below 1000 g (86 percent vs. 54 per cent, P less than 0.01 by chi-square test). We conclude that the high level of ambient illumination commonly found in the hospital nursery may be one factor contributing to retinopathy of prematurity and that safety standards with regard to current lighting practices should be reassessed.
