缺少維生素甲最易发生夜盲、干眼病,进而引起角膜軟化,为我国主要的致盲原因之一。本病多发生于小孩,直接影响我国的新生力量,故眼科或他科医生均应对本病有系統的認識,才能做好防治工作。为此笔者綜述有关文献并报告分析本科自1955年3月至1957年3月兩年內所見50例,以供参考。一、历史据埃及古書記載:公元前1600年已有人用肝治疗夜盲。公元前1500年中国已用猪肝、蜜糖、龟壳等治疗夜盲。1863年Bitot氏首先描写因营养不良而引起球結膜上白色斑点。1913年Osborne和Mendel兩氏用去奶油的牛乳飼动物,可发生干眼病并命名为干燥病“Xerosis”。Mc Collum以后提出干眼病“Xerophthalmia”
Lack of vitamin A is most prone to night blindness, dry eye, and then cause corneal softening, as one of the main causes of blindness in our country. The disease occurs in children, a direct impact on China’s emerging forces, so ophthalmology or other doctors should have a systematic understanding of the disease in order to do a good job in prevention and treatment.

In 1500 BC China had used pig liver, honey, turtle shells and other treatment of night blindness. In 1863 Bitot first described the white conjunctiva caused by malnutrition. In 1913, Osborne and Mendel used dry butter to feed their dairy animals, which developed dry eye and named it “Xerosis.” Mc Collum later proposed dry eye “Xerophthalmia”
