腎不全に合併した角膜カルシウム沈着

Corneal Calcification in Renal Failure

緒言

　腎不全に見られた角膜カルシウム沈着の症例に関して，愚者の協力を得て，従来あまり報告をみなかつた組織学的検索を行ない，Red eyeおよびBand Keratopathyについて，若干考察する機会を得たので，ここに報告する。

A 29-year-old housewife suffering from chro-nic renal failure manifested red eye accompa-nied by photophobia and feeling of grittiness. The ocular complaints wers ascribed to incipient band keratopathy. Biopsy studies were subse-quently conducted and resulted in following find-ings:

1. The red eye was induced by corneal and conjunctival calcification and by secondary con-junctival edema.

2. The calcified masses were located within the Bowman's membrane and in the corneal st-roma just below the Bowman's mambrane.

3. The deposited calcium in the corneo-con-junctival tissue was apparently derived from theconjunctival vessels.
