The medical records of 53 premature infants weighing less than 1,360 g at birth were examined. The retinas of 32 infants remained normal, while mild active retrolental fibroplasia developed in 17 babies, and severe active retrolental fibroplasia developed in four babies. The birth weight, duration of exposure of supplemental oxygen, and the amount of blood they received as transfusions were recorded. There was no significant difference in these values for those babies whose retinas remained normal and for those babies in whom mild retinopathy of prematurity developed. However, the infants in whom severe retrolental fibroplasia developed were significantly smaller in weight at birth and received more supplemental oxygen and transfused blood. There was a close correlation between the amount of blood transfused and days of exposure to supplemental oxygen. In addition, the ratio of transfused blood to days of supplemental oxygen exposure was greater in those infants in whom no retrolental fibroplasia developed and least in those infants in whom severe active retrolental fibroplasia developed.
对53名出生时体重不足1360克的早产儿的病历进行了检查。32名婴儿的视网膜保持正常，17名婴儿出现轻度活动性晶状体后纤维增生，4名婴儿出现重度活动性晶状体后纤维增生。记录了出生体重、吸氧持续时间以及输血的血量。视网膜保持正常的婴儿与出现轻度早产儿视网膜病变的婴儿在这些数值上没有显著差异。然而，出现重度晶状体后纤维增生的婴儿出生时体重明显更小，吸氧和输血更多。输血量与吸氧天数之间存在密切相关性。此外，未出现晶状体后纤维增生的婴儿的输血与吸氧天数之比最大，而出现重度活动性晶状体后纤维增生的婴儿的这一比例最小。
