In a recent study, it was reported that incidental lighting within the newborn intensive care unit setting may play a role in the development of retinopathy of prematurity. Consequently, the routine clinical management in the intensive care nursery at Yale-New Haven Hospital was modified to include shielding each premature infant's isolette, thereby decreasing the intensity of the nursery lights on an infant's eyes from a median light level of 55 foot-candles to 15 foot-candles. The effect of this reduction of light level on the incidence of retinopathy of prematurity in 161 premature infants was prospectively investigated. This group was then compared with a historic control group of 129 premature infants with similar characteristics who had been exposed to standard nursery lighting. There was no difference in the incidence and severity of retinopathy of prematurity between the two groups.
在最近的一项研究中，有报告称新生儿重症监护病房环境中的偶然光线可能在早产儿视网膜病变的发展中起作用。因此，耶鲁-纽黑文医院重症监护室的常规临床管理进行了修改，包括为每个早产婴儿的保温箱遮光，从而将保育室灯光照射在婴儿眼睛上的强度从中位数55英尺烛光降低到15英尺烛光。前瞻性地研究了这种光线水平降低对161名早产儿早产儿视网膜病变发病率的影响。然后将该组与129名具有相似特征且暴露于标准保育室照明的早产儿历史对照组进行比较。两组之间早产儿视网膜病变的发病率和严重程度没有差异。
