据美国加里弗尼亚大学洛杉矶校的D.费路浦斯博士推算,在美国仅1979年因未成熟儿网膜病而失明的有546人。日本因此而失明者一年间推算为80人。美国是日本的七倍。以相同体重的婴儿做比较,则美国比日本均衡且失明率低。尽管如此,但失明者多,这是因为极小未成熟儿多。在日本一年中有164万婴儿出生,其中不足1kg的有400人,1～1.5kg的4,500人左右。而美国出生340万人中,不足1kg的17,000人,1～1.5kg的20,000人。
According to Dr. D. Ferruppius of the University of California, Los Angeles, California, there are 546 people in the United States who were blind in only immature retinal disease in 1979. Therefore, blind people in Japan are estimated to be 80 in one year. The United States is seven times Japan. When compared with infants of the same weight, the United States is more balanced than Japan with a low rate of blindness. In spite of this, there are many blind people because of immature children. In Japan, 1.64 million babies were born in a year, of which 400 were less than 1 kg and 4,500 were from 1 to 1.5 kg. In the United States, about 3.4 million people were born, less than 1kg of 17,000 people, 1 ~ 1.5kg of 20,000 people.
