併発白内障の房水組成について

Composition of Aqueous Humour in Complicated Cataract

緒言

　水晶体は主として房水により栄養されており，房水組成の異常は水晶体の代謝障害すなわち白内障発生の直接的原因となりうる。いわゆる併発白内障がこれに相当するものと考えられるが，併発白内障発生機構解明の一つの手段としてブドウ膜炎によると思われる併発白内障，老人性白内障，糖尿病患者の白内障及び正常者の房水，血清組成について比較検討を行なつた。

Electrolytes (Na⁺, K⁺ and Ca²⁺) and glucose in aqueous humour and serum of patients with complicated, senile cataracts and cataracts of diabetics were measured spectrophotome-trically. The results have been discussed, com-paring with those in the control, normal eyes.

In aqueous humour of both groups of patients with complicated and senile cataracts, concen-trations of glucose as well as calcium were found to decrease. On the contrary, glucose concentration increased in the diabetic one.

In electrolyte concentration ratio of aqueous humour and serum, no significant difference was found between patients and the control.
