ビタミンA欠乏症によると思われるうつ血乳頭の1例

Papilledema by Vitamin A Deficiency in a 5 Years Old Boy

Ⅰ．はじめに

　ビタミンA欠乏に起因する脳圧亢進に就いては，1933年Blackfan以来数例の報告があるのみで，眼科領域に於ける報告は未だない。

　我々はビタミンA欠乏症を来した患者に，脳圧亢進，及びうつ血乳頭を認め，ビタミンAを投与した所，著明な改善を認めたので，茲に報告する。

A case of avitaminosis A in a 5-year-oldmale child is reported. Xerophthalmia, night blindness, slight anemia, albuminuria, intra-cranial hypertension of 500mm as maximal value and papilloedema comprised the chief clinical findings.

Administration of vitamin A resulted in rapid disappearance of symptoms including increased intracranial pressure. The affection by measles by the patient 3 years before is considered to have formed a predisposing factor for the development of avitaminosis A which is in itself an extremely rare condition today
