An account is given of asymptomatic diabetes mellitus. To determine the incidence in 200 patients with senile cataract 3 tests are described, namely, a modified standard glucose tolerance test, a provocative steroid glucose tolerance test, and a standard glucose tolerance test. Known diabetics and patients with a fasting blood glucose in excess of 5.5 mmol/l or glycosuria were excluded. Eighty-eight patients had an abnormal modified standard glucose tolerance test. Of these, 41 had an abnormal curve after a provocative steroid glucose tolerance test, and 30 had an abnormal curve after a standard glucose tolerance test. Forty-three of the 71 patients with abnormal curves had no glycosuria, although the blood glucose level exceeded an arbitrary renal threshold of 10 mmol/l. Asymptomatic diabetes was diagnosed in patients of all age groups. It is concluded that glucose intolerance is common in patients with senile cataract who show no glycosuria and have a normal fasting blood sugar on routine examination.
本文介绍了无症状糖尿病。为确定200例老年性白内障患者的发病率，描述了3种检测方法，即改良标准葡萄糖耐量试验、激发性类固醇葡萄糖耐量试验和标准葡萄糖耐量试验。已知糖尿病患者以及空腹血糖超过5.5 mmol/l或有糖尿的患者被排除在外。88例患者改良标准葡萄糖耐量试验异常。其中，41例在激发性类固醇葡萄糖耐量试验后曲线异常，30例在标准葡萄糖耐量试验后曲线异常。71例曲线异常的患者中有43例无糖尿，尽管血糖水平超过了10 mmol/l这一任意设定的肾阈值。各年龄组患者均诊断出无症状糖尿病。结论是，在老年性白内障患者中，葡萄糖耐量异常很常见，这些患者无糖尿且常规检查空腹血糖正常。
